Do bracers of armor stack with magic armor enhancements and special abilities? Equals() method is defined in Object class in Java and used for checking equality of two objects defined by business logic. In Many-to-one the many side will keep reference of the one side. 6. Connect and share knowledge within a single location that is structured and easy to search. Why do some airports shuffle connecting passengers through security again. Descendants classes, like String, can define what it means for two strings to be == by overriding the .Equals method. Although array and pointer are different things, following properties of array make them look similar. Java cannot do that. Difference Between dispose() and finalize() in C#, Difference Between throw and throws in Java, Difference Between Error and Exception in Java, Difference Between Static and Final in Java, Difference Between Checked and Unchecked Exception in Java, Difference Between while and do-while Loop, Difference Between Guided and Unguided Media, Difference Between Preemptive and Non-Preemptive Scheduling in OS, Difference Between View and Materialized View, Difference Between Server-side Scripting and Client-side Scripting, Difference Between Assembler and Interpreter, Difference Between Actual and Formal Parameters, Difference Between Cache Memory and Register. This means that ArrayList internally contains an array of values and a counter variable to know the current size at any point. The first pointer, head, points to the first element and is updated whenever a new element is inserted at the beginning. The values returned by this method become meaningful only when the difference between two such values, obtained within the same instance of a Java virtual machine, is computed. To fetch an element, the list needs to be traversed from the beginning (or the end, whichever is closer) and follow each of the nodes' connections until the wanted element is found. For example, say if the weapon was actually a class instead of a String? Both definitions work in C also, but the second definition with void is considered technically better as it clearly specifies that main can only be called without any parameter. The Java String class (and no class in Java) has a way to override == to make it behave the way it should behave. Improved By : In other contexts there is a difference between ++i and i++, but not for loops. The keyword final is an access modifier, finally is a block and finalize is a method. int and void are its return type. Here we need the DAO class for the service class. Difference between Java and C language; What is the difference between 'except Exception as e' and 'except Exception, e' in Python? 8. The finally block executes after the try/catch block and before the code following try/catch block. ArrayList and LinkedList are two different implementations of the List interface. I sometimes find the testing with the mocking hard to understand and design for a class. Difference Between Method Overloading and Method Overriding in Java; Difference between Primary key and Unique key; integer, float, and void are fundamental data types. Small methods that are declared final can be made inline by the compiler which will reduce the overhead of function calling and increase performance enhancements. If I disassemble this class using javap.exe I get this: If I change the loop so it uses i++ and disassemble again I get this: When I compare the two, TextPad tells me that the two are identical. What's the difference between @Component, @Repository & @Service annotations in Spring? boolean variable will be initialized with a false, byte, short, char, int and long will be initialized with zero, and float and double variables will be initialized with 0.0 value in Java. If an element needs to be inserted at the beginning, the method can be called with an index of 0. Note: The difference between primitive and reference type makes it necessary to rely on boxing to convert primitives in Object instances and vise versa. We make use of First and third party cookies to improve our user experience. We will also get same behaviour using @Spy annotation. In a common coding convention, final variables are declared in UPPERCASE. 6. WebBoth i++ and ++i are short-hand for i = i + 1.. Difference between StringBuilder and StringBuffer, Difference between "wait()" vs "sleep()" in Java. This is because the entire array is stored in one unique place in memory. Article Contributed By : CoderSaty @CoderSaty. What is the difference between equals() and == in Java? Not the answer you're looking for? Class variables also known as static variables are declared with the static keyword in a class, but Java cannot do that. . The values returned by this method become meaningful only when the difference between two such values, obtained within the same instance of a Java virtual machine, is computed. In this article, lets check out how to convert int to String in Java.. Finds the minimum / maximum number from the list and sort it in ascending / descending order. Also, you should know that some people like to call final non-static variables. Statement(s) is executed once the condition is checked. If elements are going to be fetched often, it makes little sense to use LinkedList since fetching is slower compared to ArrayList. To represent floating point numbers, we use float, double and long double.Whats the difference? However, fetching any other element is O(N) because we can't just access them via an index. Output: from m1 Inside static block Value of a : 20 from main Non-Static Variable. Public vs Package Access Modifiers in Java. WebI just looked at the code once more and it seems the website is wrong (Try calculating yourself). Find centralized, trusted content and collaborate around the technologies you use most. My C code for 2d array creation and printing doesn't return any value. If an element is added, the size is increased. This link has a good tutorial for Mockito framework, A "mocking framework", which Mockito is based on, is a framework that gives you the ability to create Mock objects ( in old terms these objects could be called shunts, as they work as shunts for dependend functionality ) WebNullPointerExceptions are exceptions that occur when you try to use a reference that points to no location in memory (null) as though it were referencing an object.Calling a method on a null reference or trying to access a field of a null reference will trigger a NullPointerException.These are the most common, but other ways are listed on the public static void exit(int status) Terminates the currently running Java Virtual Machine. The main difference between Sentinel and Counter Controlled Loop in C is that in a Sentinel Controlled Loop, exactly how many times loop body will be executed is not known and in a Counter Controlled Loop, how many times loop body will be executed is known.. An ArrayList is a resizable array that grows as additional elements are added. Character is used for characters. Inserting an element at the end is fairly simple, especially for a structure like an ArrayList. If you omit the date, i.e. void compute_area(double r) Public vs Protected vs Package vs Private Access Modifier in Java. Integration tests use the real dependencies. Vote for difficulty. The difference between One-to-many, Many-to-one and Many-to-Many is: One-to-many vs Many-to-one is a matter of perspective. Why do we use perturbative series if they don't converge? The Java String class (and no class in Java) has a way to override == to make it behave the way it should Although array and pointer are different things, following properties of array make them look similar. Difference between an Integer and int in Java with Examples. void compute_area(double r) Public vs Protected vs Package vs Private Access Modifier in Java. Thus, generally, if you retrieve a lot of elements from within the list, an ArrayList is preferred. ; Illustration: Given arr[] = {1, 15, 10}, n = 3, k = 6. The algorithm maintains two subarrays in a given array. Note2: A type parameter describes a type having an optional lower or upper bound and can be referenced by name within its context (in contrast to the wild card type). The entire list structure thus consists of mutually connected nodes. Lists are therefore ordered collections (unlike sets) which also allow duplicates. The subarray is already sorted. For ArrayList, insertion is O(1) only if added at the end. Mathematica cannot find square roots of some matrices? Japanese girlfriend visiting me in Canada - questions at border control? rev2022.12.11.43106. Dual EU/US Citizen entered EU on US Passport. If an element is removed, the size is decreased. MockitoAnnotations.initMocks(this) call, resets testing object and re-initializes mocks, so remember to have this at your @Before / @BeforeMethod annotation. So the difference between those two times is 12 hours, 0 minutes and 50 seconds and never 23 hours, 34 minutes and 12 seconds. Do you have a mini-example of your requirement? WebThe first difference between primitive and reference types is that the former can never be null if no value is assigned they take their default value e.g. Once again, this is because of the head and tail pointers which can be used to insert an element at any of these two positions instantaneously. From simple plot types to ridge plots, surface plots and spectrograms - understand your data and learn to draw conclusions from it. We can see this operation is performed in constant time, or O(1). This makes the addition of elements to an ArrayList a relatively inefficient operation. Some of the examples of errors are system crash error and out of memory error. Hence, the function calling can be resolved at compile time. For me, mocking is to isolate the fixture to be tested in order to unit-test. Are defenders behind an arrow slit attackable. The basic difference between the type int and long is of their width where int is 32 bit, and long is 64 bits. @InjectMocks creates an instance of the class and injects the mocks that are created with the @Mock (or @Spy) annotations into this instance. ; Illustration: Given arr[] = {1, 15, 10}, n = 3, k = 6. Difference between const int*, const int * const, and int const * Unidirectional vs Bidirectional will not affect the mapping but will make difference on how you can access your data. In Java, all the variables must be declared before use. : Method overriding is used to provide the specific implementation of the method that is already provided by its super class. Inserts the value in the presorted array to sort the set of values in the array. Enjoy unlimited access on 5500+ Hand Picked Quality Video Courses. In the ArrayList implementation, this is done with a simple for loop going from 0 to size-1 and checking if the element at the current index matches the given value: This is quite literally a linear search, which isn't very efficient, but really the only way you can search for an element in a shuffled collection (if we ignore metaheuristic algorithms and approximations). Can we keep alcoholic beverages indefinitely? Difference between Java and JavaScript. They have their differences which are important to understand to utilize them properly. Mockito is an open source testing framework for Java released under the MIT License, it is a "mocking framework", that lets you write beautiful tests with clean and simple API. Check out our hands-on, practical guide to learning Git, with best-practices, industry-accepted standards, and included cheat sheet. If you are not running on Java 8, then there are two ways to calculate the difference between two dates in Java in days, either by using standard JDK classes e.g. Descendants classes, like String, can define what it means for two strings to be == by overriding the .Equals method. Though, a good thing about ArrayLists is that you can get to that element really easily. Difference between int main() and void main() and main() Like any other function, main is also a function but with a special characteristic that the program execution always starts from the main. ArrayList contains a single array for data storage. C in Depth: The Complete C Programming Guide for Beginners. Fastest way to determine if an integer's square root is an integer. @InjectMocks annotation allows to inject into the underlying object the different (and relevant) mocks created by @Mock. Removing an element from a LinkedList works by unlinking the previous and subsequent pointers from the element we'd like to remove. If an element is removed, the size is decreased. School Guide: Roadmap For School Students, Data Structures & Algorithms- Self Paced Course, Difference Between for loop and Enhanced for loop in Java, Difference between Open-Loop Control System and Closed-Loop Control System, Difference between while and do-while loop in C, C++, Java, Difference between for and while loop in C, C++, Java, Difference between Nested Loop Join and Hash Join, Difference between Nested Loop join and Sort Merge Join. No spam ever. In every iteration of the selection sort, the minimum element (considering In addition to changing the value of i, they also return the value of i, either before adding one (i++) or after adding one (++i).In a loop the third component is a piece of code that is executed after each iteration. If you are not running on Java 8, then there are two ways to calculate the difference between two dates in Java in days, either by using standard JDK classes e.g. WebThe values returned by this method become meaningful only when the difference between two such values, obtained within the same instance of a Java virtual machine, is computed. Dependency injection frameworks like Spring allow you to inject your proxy objects without modifying any code, the mock object expects a certain method to be called and it will return an expected result. Each variable has a type, such as int, double or Object, and a scope. Similarly, in Spring framework all the @Autowired beans can be mocked by @Mock in jUnits and injected into your bean through @InjectMocks. You just extend the length by one, and insert the element at the end: However, inserting at a given position is a bit trickier. What this says is that from the point of view of the generated byte code there's no difference in a loop. What is the main difference between int.Parse() and Convert.ToInt32 in C#? How many transistors at minimum do you need to build a general-purpose computer? Why does the following print when I use the increment operator? What is the difference? This method performs cleanup activities for the object before it is being destroyed. Vote for difficulty. How do I create a Java string from the contents of a file? Many people have given a great explanation here about @Mock vs @InjectMocks. So, we mock it and inject it in the service class instance. Exceptions and errors both are subclasses of Throwable class. Why is processing a sorted array faster than processing an unsorted array? Public vs Protected in C++ with Examples. Similarities and Difference between Java and C++. When a method returns to the caller from inside the try/catch block via an uncaught exception or an explicit return statement, the finally block gets executed just before the method returns to the caller. There's no need for additional traversal logic. @WesternGun I don't understand how your understanding of mocking is different from the part you quoted. Difference between void main and int main in C/C++. Compare the current element (key) to its predecessor. The fifth element, for example, points both to the fourth element and the sixth element. Here the main difference between 'while' loop and 'do while' loop is that 'while' loop check condition before iteration of the loop, whereas 'do-while' loop checks the condition after the execution of the statements inside the loop. Connect and share knowledge within a single location that is structured and easy to search. It might be that statement(s) gets executed zero times. All rights reserved. How do I arrange multiple quotations (each with multiple lines) vertically (with a line through the center) so that they're side-by-side? Initialization may be outside or in condition box. To represent floating point numbers, we use float, double and long double.Whats the difference? WebIf you are not running on Java 8, then there are two ways to calculate the difference between two dates in Java in days, either by using standard JDK classes e.g. This one seems to be a long term solution. Note2: A type parameter describes a type having an optional lower or upper bound and can be referenced by name within its context (in contrast to the wild card type). Can they be used in tandem on the same object? This custom data structure is a Node. This is the reason why, there is no difference between i++ and ++i in the for loop which has been used. The idea for this is given below: The idea is to increase the first i towers by k and decrease the rest tower by k after sorting the heights, then calculate the maximum height difference. Difference Between java.sql.Time, java.sql.Timestamp and java.sql.Date in Java. java.util.Date and java.util.Calendar or by using the joda-time library. Errors mostly occur at runtime that's they belong to an unchecked type. The selection sort algorithm sorts an array by repeatedly finding the minimum element (considering ascending order) from the unsorted part and putting it at the beginning. Japanese girlfriend visiting me in Canada - questions at border control? It is less efficient than the Insertion sort. Lists are some of the most commonly used data structures. Java cannot do that. In this example the instance would be ClassB. LinkedList's implementation allows us to add elements at any given index, fairly easily. suppose we have a car. Java final java A).finalabstractfinal Method Overloading Method Overriding; 1) Method overloading is used to increase the readability of the program. Difference Between java.sql.Time, java.sql.Timestamp and java.sql.Date in Java. In this article, we'll go through both of these implementations, observe their inner workings and discuss their performance. The remaining subarray is unsorted. Learn how to calculate the difference between dates in Java, using native approach, as well as external libraries. The selection sort algorithm sorts an array by repeatedly finding the minimum element (considering ascending order) from the unsorted part and putting it at the beginning. What is the difference between 'except Exception as e' and 'except Exception, e' in Python? I'll add more to the loop example and try again to see. This means that no matter the size of the array, any requested element will be returned instantaneously, without the need to traverse the list. I would not say that "By using mock objects in your tests you are essentially going from normal unit testing to integrational testing". NullPointerExceptions are exceptions that occur when you try to use a reference that points to no location in memory (null) as though it were referencing an object.Calling a method on a null reference or trying to access a field of a null reference will trigger a NullPointerException.These are the most common, but other ways are listed on the NullPointerException javadoc page. Public vs Protected in C++ with Examples. We do not currently allow content pasted from ChatGPT on Stack Overflow; read our policy here. what if someManager had 3 different constructors, how would it know which one to use ? The first difference between primitive and reference types is that the former can never be null if no value is assigned they take their default value e.g. Exchange operator with position and momentum. Both definitions work in C also, but the second definition with void is considered technically better as it clearly specifies that main can only be called without any parameter. WebKey Differences Between int and long. I don't understand how ++i and i++ works in a for-loop. Condition is checked after the statement(s) is executed. The types int and long when counted in bytes instead of bits the type int is 4 bytes and the type long is just twice if type int i.e. The first element points to the second one, The finally block is used to clean up the resources utilised by try and catch block. This makes the addition of elements to a LinkedList a highly efficient operation. float has 7 decimal digits of precision.double is a 64-bit IEEE 754 double precision Floating Point : 2) Method overloading is performed within class. No. Which implementation should be used depends on the exact use cases. The difference between One-to-many, Many-to-one and Many-to-Many is: One-to-many vs Many-to-one is a matter of perspective. Algorithm:To sort an array of size n in ascending order: Below is the image to illustrate the Insertion Sort: The selection sort algorithm sorts an array by repeatedly finding the minimum element (considering ascending order) from the unsorted part and putting it at the beginning. Overridden methods call, are resolved dynamically, but when a method is declared as final, it can not be overridden. The selection sort algorithm sorts an array by repeatedly finding the minimum element (considering ascending order) from the unsorted part and putting it at the beginning. The remaining subarray is unsorted. Alternatively, if we specify an index, both linkLast() and linkBefore() get called: No matter how big the list is, only two pointers need changing. In this section, we'll briefly compare the two implementations from the performance perspective: We can see that fetching elements from a list is always O(1) for ArrayList. The @InjectMocks annotation tries to instantiate the testing object instance and injects fields annotated with @Mock or @Spy into private fields of the testing object. It mainly occurs in the code written by the developers. What's the difference between --i and i--? If a property is string, my contract is: assign any chars up to ~2bil length.If a property is DateTime, my contract is: assign any numbers within the limits of DateTime, which I can look up.If the creator adds constraints to the setters, those constraints are not We do not currently allow content pasted from ChatGPT on Stack Overflow; read our policy here. Difference Between C++ and Java; What is the difference between throw e and throw new Exception(e) in catch block in java? C in Depth: The Complete C Programming Guide for Beginners. Difference between Compile-time and Run-time Polymorphism in Java; Difference between List and Array in Python; integer, float, and void are fundamental data types. Is it possible to hide or delete the new Toolbar in 13.1? The difference is subtle. In all other cases (adding at the beginning or in the middle), complexity is O(N), because the right-hand portion of the array needs to be copied and shifted. Public vs Protected Access Modifier in Java. How do I break out of nested loops in Java? finalize() method executes just before the destruction of the object. Article Contributed By : CoderSaty @CoderSaty. These variable are created when the block in entered or the function is called and destroyed after exiting from the block or when the call returns from the function. In your test class, the tested class should be annotated with @InjectMocks. Each node contains its element and two pointers: a link to the previous node and the link to the next node. Values from the unsorted part are picked and placed at the correct position in the sorted part. Short answer: for native types nothing. Many existing instances. Pointers, arrays, structures, and unions are derived data types. 9. (1) Final variable becomes constant, and it can't be reassigned. So the difference between those two times is 12 hours, 0 minutes and 50 seconds and never 23 hours, 34 minutes and 12 seconds. Generally, inserting elements performs equally between both an ArrayList and a LinkedList, unless you're mainly working with the first and last elements. Array after sorting => arr[] = {1, 10, 15}. Can we change the order of public static void main() to static public void main() in Java? That's because Mockito will check the Type Signature of Game class, which is Player and List
. In every iteration of the selection sort, the minimum element (considering ascending order) from the unsorted subarray is picked and moved to the sorted subarray. In C++, there is no difference, both are same. So far, we've discussed how ArrayList and LinkedList work under the hood. "Finally" block executes just after the execution of"try-catch" block. Array after sorting => arr[] = {1, 10, 15}. Would like to stay longer than 90 days. To represent floating point numbers, we use float, double and long double.Whats the difference? Vote for difficulty. However, this example helps a lot to provide the overview. Unfortunately, Java's old Date and Calendar API is buggy and not intuitive, so many of us by default use Joda for all date Since it's an interface, it simply provides a list of methods that need to be overridden in the actual implementation class. Why does the USA not have a constitutional court? Ready to optimize your JavaScript with Rust? This method is invoked by the garbage collector before it destroys the object completely. Absolute +1 for this answer! Difference between Compile-time and Run-time Polymorphism in Java; Difference between List and Array in Python; integer, float, and void are fundamental data types. stackoverflow.com/search?q=i%2B%2B+%2B%2Bi. boolean variable will be initialized with a false, byte, short, char, int and long will be initialized with zero, and float and double variables will be initialized with 0.0 value in Java. Is there a difference between x++ and ++x in java? @InjectMocks annotation can be used to inject mock fields into a test object automatically. Why is processing a sorted array faster than processing an unsorted array? This is a sample code on how @Mock and @InjectMocks works. How could my characters be tricked into thinking they are on Mars? Difference between Sentinel and Counter Controlled Loop in C is given below: suppose we have a car. The Java String class (and no class in Java) has a way to override == to make it behave the way it should behave. Java final java A).finalabstractfinal Difference between system level exception and Application level exception. Article Contributed By : Code_r Difference between Go and Java. Final is a keyword applicable to classes, variables and methods. Public vs Package Access Modifiers in Java. Output: from m1 Inside static block Value of a : 20 from main Non-Static Variable. float has 7 decimal digits of precision.double is a 64-bit IEEE 754 double precision Floating Point Final is a "Keyword" and "access modifier" in Java. Note: The difference between primitive and reference type makes it necessary to rely on boxing to convert primitives in Object instances and vise versa. Initially maxHeight = arr[n 1] = 15 Compiler Error: incompatible types when assigning to type 'int[2]' from type 'int *' See the previous post on this topic for more differences. Difference between Java and C language; What is the difference between 'except Exception as e' and 'except The difference between One-to-many, Many-to-one and Many-to-Many is: One-to-many vs Many-to-one is a matter of perspective. class Car { bool HasGPS; bool IsCityCar; bool IsSportsCar; int Cylenders; int Seats; public: void Car(bool hasGPs=false,bool IsCityCar=false,bool IsSportsCar=false, int Cylender=2, int Seats=4); }; C in Depth: The Complete C Programming Guide for Beginners. Difference between StringBuilder and StringBuffer. You can convert a string variable to a numeric value and a numeric value into a string variable. LinkedLists have O(1) complexity for removing from the beginning or end, and O(N) in other cases. An object may be holding some non-java resources such as file handle; then it must be freed before it is destroyed. Does this work for transitive dependencies or only direct members? (MPLS) 7. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Is it illegal to use resources in a University lab to prove a concept could work (to ultimately use to create a startup). The keyword final is an access modifier, finally is a block and finalize is a method. Read our Privacy Policy. Both i++ and ++i are short-hand for i = i + 1.. for loop: for loop provides a concise way of writing the loop structure. Lists are data structures used for sequential element storage. If your loop-end expression was more complicated, it might very well make a difference. Listed below are different ways to convert int to string in Java: How we convert int to String in Java: using Integer.toString(int) How we convert int to String in Java: using String.valueOf(int) How we convert int to String in Java: using String.format() Difference Between Virtual Private Network (VPN) and Proxy. Thank you! 8. In Java, List is an interface under the java.util package. In other words, a mock object is used to imitate the real object your code is dependend on, you create a proxy object with the mocking framework. The algorithm maintains two subarrays in a given array. Privacy. differences in year, month and day, you'll get the start time 7:45:55 and the end time 19:46:45 (or 7:46:45 PM). In below example @InjectMocks has used to inject the mock dataMap into the dataLibrary . A good example is "A State has Cities". Difference between Sentinel and Counter Controlled Loop in C, Difference between for loop in C and Python, Difference between forEach() and map() loop in JavaScript. The implementation of the same method looks like: First, a check is made to make sure the index isn't 0 or above the size of the LinkedList. Easy Normal Medium Hard Expert. LinkedList does this a tad differently. The keyword final is applicable to the classes, variables and methods of the classes finally is a block associated with the try catch block that is used to handle exceptions, finalize is a method that operates only on objects. Difference between Java and JavaScript. Initially maxHeight = arr[n 1] = 15 ArrayList and LinkedList are two different implementations of these methods. Pointers, arrays, structures, and unions are derived data types. A good example is "A State has Cities". Both i++ and ++i are short-hand for i = i + 1.. Mockito will inject it for you. Thus, removal of elements is generally the same, unless you mainly work with the initial and last elements. Finally, in the case of a linked list, we can assume the existence of two pointers which continuously monitor the first and the last elements of the list. C++ Server Side Programming Programming. Difference between Java and C language; What is the difference between 'except Exception as e' and 'except Exception, e' in Python? Finding an element of a list, be it an ArrayList or a LinkedList should be fairly similar. (MPLS) 7. Ready to optimize your JavaScript with Rust? So I was thinking of using. 10.

The variable once declared as final becomes constant and cant be reassigned again, a method declared as final cant be overridden, and class once declared as final can never be inherited. Whereas, @InjectMocks is for injecting mock fields into the tested object automatically. WebThe values returned by this method become meaningful only when the difference between two such values, obtained within the same instance of a Java virtual machine, is computed. Not the answer you're looking for? java.util.Date and java.util.Calendar or by using the joda-time library. The first difference between primitive and reference types is that the former can never be null if no value is assigned they take their default value e.g. A-143, 9th Floor, Sovereign Corporate Tower, We use cookies to ensure you have the best browsing experience on our website. Probably too late to this thread but just in case someone sees this: What if the class I am doing an @Mock on itself has some dependencies that need to be injected? Both of them increase the variable i by one. This is because there's no way to know a priori where any particular element is stored, unless the array is sorted and evenly distributed. The insertion sort is Adaptive, i.e., efficient for data sets that are already substantially sorted: the time complexity is, Selection sort is an in-place comparison sorting algorithm. Difference between comparing String using == and .equals() method in Java. Notice that you don't even have to create a new Game object. JLS14.14.1, The basic for Statement, makes it clear that the ForUpdate expression(s) are evaluated and the value(s) are discarded. 8. LinkedList doesn't have an array but a double-ended queue of mutually-connected elements instead. No. After that, the previous element is linked to the next in line. Note you must use @RunWith(MockitoJUnitRunner.class) or Mockito.initMocks(this) to initialize these mocks and inject them (JUnit 4).
