- class Student { public : int * grades ; Student ( int n ) { // dynamically allocate an array of grades of size n } ~Student ( ) { // delete the array of grades } };JAVA LANGUAGE Create an ArrayList, Name it YourRegNoandName that can hold Integers, and fill each slot with a different random value from 1-50. Display those values on the screen, and then prompt the user for an integer to search through the ArrayList, and if the item is present, say “FOUND”. It is not necessary to display anything if the value was not found. If the item is in the ArrayList multiple times, it's okay if the program prints the message more than once. ALSO SCREENSHOT THE OUTPUTfunction myChoice(items) {if (!this.value && !this.items) {this.items = items[0];} else if (!this.value || (params.length > 0 && params[0] == "rechoose")) {let index = Math.floor(Math.random() * (this.items.length - 0)) + 0;this.value = this.items[index];return this.value;}return this.value;} var a = myChoice([1, "a", 3, false]);console.log(myChoice(3, 12));console.log(myChoice(51, -2));console.log(myChoice("happy", false));console.log(myChoice([1, 2, 3]));console.log(myChoice("rechoose"));console.log(myChoice(a, a)); these are directions and examples myChoice( items ) This function accepts a list of items as input and creates a function that returns a randomly-chosen item. After choosing a random item, that same item will be always be returned, regardless of the functions input, with one exception. If the first input is the string 'rechoose', then a new random item will be chosen and therafter returned. this is KEYYYY!! Examples var a = myChoice( [1, "a", 3, false]…

- Rename the show method to people Override the show method in student and in the other class you created (this will be the polymorphic method) In main program, create an array of 3 objects of class people Instantiate each array position with a different object (people, student, other) With a loop, display all the objects in the array.Computer Science Question , Create a GUI for the code below import java.util.ArrayList; import java.util.List; public class Budget { private String name; private double balance; private List<Expense> expenses; public Budget(String name, double balance) { this.name = name; this.balance = balance; this.expenses = new ArrayList<>(); } public void addExpense(Expense expense) { if (expense.getAmount() <= this.balance) { this.expenses.add(expense); this.balance -= expense.getAmount(); } else { System.out.println("Error: not enough funds to add expense"); } } public double getBalance() { return this.balance; } public List<Expense> getExpenses() { return this.expenses; } } Step 2/2 Expense.java: public class Expense { private String name; private double amount; public Expense(String name, double amount) { this.name = name; this.amount = amount; } public double getAmount() { return this.amount; } public String toString() { return this.name + ": "…For any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces).

- Define a class called Book. This class should store attributes such as the title, ISBN number, author, edition, publisher, and year of publication. Provide get/set methods in this class to access these attributes. Define a class called Bookshelf, which contains the main method. This class should create a few book objects with distinct names and store them in an ArrayList. This class should then list the names of all books in the ArrayList. Enhance the program by providing a sort function, which will sort the books in ascending order of their year of publication. Create a few more Bookobjects with the same names but with different edition numbers, ISBNs, and years of publication. Add these new Book objects to the ArrayList, and display the book list sorted by book name; for duplicate books of the same name, sort the list by year of publication. (Hint: You will need to define a comparator class that takes two Book objects as parameters of the compareTo This method should do a two-step…Create a program that will track student names and their grades and perform some simple statistics. In a main class create an ArrayList or array that will hold Student names. Create a second (parallel) ArrayList or array that will hold student scores, represented as integers from 0-100. Prompt the user to enter some students (for your purposes, enter information for at least three). Then present a menu for the user. The menu will contain the following options: Find student with the highest grade (print out the name of the student) Find grade average (return the grade average back to the calling method) print information of all students exit program Create methods in your main class for these options. Keep the your ArrayList or array inside your main method and pass it to the other methods; it should not be a global variable. Validate the grade; the user should not enter anything below 0 or above 100.Random walk. A Java programmer begins walking aimlessly. At each time step, she takes one step in a random direction (either north, east, south, or west), each with probability 25%. She stops once she is at Manhattan distance r from the starting point. How many steps will the random walker take? This process is known as a two-dimensional random walk.
