In the Utils class provided to you in this exercise, please fill in the details for a method called swapArray(). You can either upload a file or use the Edit tab to submit your work. The VPL tester will pass an arbitrary array of type integer to your method, along with the value of the locations in the array of two values that need to be swapped (exchanged). For instance, in the illustration below, the method swapArray is told to swap the values in positions 0 and 2 of an array made up of {10, 20, 30, 40, 50}. The three input parameters to the method are the array, as well as the two array indices (i and j) that control which elements to swap.
Your task is to write the contents of the method that can execute this swap.
In F3, students will be tasked with taking input from a file to create an *Array* of FeetInches (2 parameters). When all the FeetInches have been stored, any FeetInches at least 1 foot will be converted and added to an *ArrayList* of Circles (one parameter). Students will then complete the compareTo method found in the Circle class, sort the ArrayList of Circles, and then output the radius' of the new circle.
The first integer in the file input will tell us how many FeetInches objects will be made using the fileInput, and the numbers after are the data for those Objects. Use this first integer in your for Loops.
A template with main, Circle, and FeetInches class, as well as the file input, is attached below. Please follow along with comments and reach out if you have any questions.
package f3_template;
public class Circle implements Comparable <Circle>{//attribute private int radius; //constructorspublic Circle(){radius=0;}public Circle(int r){radius=r;}//accessorspublic…

- Test the Baby class below by writing a client program which uses an array to storeinformation about 4 babies. That is, each of the four elements of the arraymust store a Baby object.If you have an array for baby names and another array for baby ages,then you have missed the point of the exercise and therefore not metthe requirement of this exercise.A Baby class object stores the required information about a Baby. Soeach Baby object will have its own relevant information, and thus eachobject must be stored in one element of the array.The client program should:a. Enter details for each baby (name and age) and thus populate theBaby arrayb. Output the details of each baby from the array (name and age)c. Calculate and display the average age of all babies in the arrayd.

But you should be able to try your templated class out with types string, MyString, double, FeetInches, Fraction, etc. I would encourage you to try these out. Also, create a programmer-defined exception class named "DuplicateMemberError" and add an if statement to each of the two mutators to throw this exception if the precondition has not been met. The precondition is given as a comment in the header file. Notice that you can test your exception handling by entering the same number twice when prompted for two numbers. Put your class in a namespace named "cs_pairs" Finally, to show that your class will work with different types, and also to show that you know how to code a client that uses the templated class, modify the given client file so that it uses your class using int as the type parameter, and then, in…arrow_forwardConvert the OrderedPair class, which is provided below, into a templated class.

Instead of having them return True/False, modify each one to throw an exception ifinvalid data is passed.Modify these methods in the following way:• add_hours()o If the number of hours being added is less than 0, throw an exception• add_sales()o If the amount of sales being added is less than 0, throw an exception• set_employee_number()o The employee number must be an integer.

Inside the class is a static, two-dimensional arrayof strings named ELEMENTS that contains information about every element in theperiodic table, so: ELEMENTS[0] is { "1", "Hydrogen", "H", "1.007" }; ELEMENTS[1] is { "2", "Helium", "He", "4.002" } and so on ... Add a static method to this class that uses the array to build a datastructure of elements such that it is fast and easy to find an element usingonly its symbol.

Therefore, instead of saying: chessBoard[row][column] for an array of objects, overload the function call operator to allow the alternate form: chessBoard(row, column) A sample output of your program should look like follows: The value of each array element is the product of the row and column values.

- Suppose that the bag class is efficiently implemented with a fixed array with a capacity of 4000, as in Chapter 3 of the class text. We execute these statements: bag b; b.insert(5); b.insert(4); b.insert(6); b.erase_one(5); Group of answer choices b.used is 2, b.data[0] is 4, b.data[1] is 6 b.used is 2, b.data[0] is 6, b.data[1] is 4 b.used is 3, b.data[0] is 4, b.data[1] is 6 b.used is 3, b.data[0] is 6, b.data[1] is 4arrow_forwardImplement the buildDistributionArray function to take an array of scores, built by parseScores, as an argument. A grade distribution array of length 5 is returned. Loop through the scores array and tally up the number of A, B, C, D, and F scores using the standard scoring system (90 and above = A, 80‐89 = B, 70‐79 = C, etc.). Store these totals in a distribution array where the number of As is the first number, number of Bs is the second number, etc. Ex: ["45","78","98","83","86","99","59"] → [2, 2, 1, 0, 2] buildDistributionArray returns [0, 0, 0, 0, 0] when the scoresArray argument is empty.arrow_forwardFind all the indexes whose labels equal 2 using np.where and the label array y.

This class includessome interesting methods for working with Arrays and ArrayLists.For example, the ArrayAndArrayList class has a “findMax” method which finds and returns themax number in a given array. For a defined array: int[] array = {1, 3, 5, 7, 9}, callingfindMax(array) will return 9.There are 4 methods that need to be implemented in the ArrayAndArrayList class:● howMany(int[] array, int element) - Counts the number of occurrences of the givenelement in the given array.● findMax(int[] array) - Finds the max number in the given array.● maxArray(int[] array) - Keeps track of every occurrence of the max number in the givenarray.● swapZero(int[] array) - Puts all of the zeros in the given array, at the end of the givenarray.Each method has been defined for you, but without the code.
