Java
Write array methods that carry out the following tasks for an array of integers by creating and
completing the “WorkingWithArrays” class below. Add documentation comments for each method.
Provide a test program called ‘Lab5_yourID.java” that tests methods of WorkingWithArrays class.
In your test program, use random class to generate array values.
public class WorkingWithArrays
{
private int[ ] values; //declare instant variables
//constructor
public WorkingWithArrays (int[ ] initialValues) {values = initialValues;}
public void MoveOddElements( ) { … }
public boolean containDuplicate( ) {…}
}
• Method MoveOddElements: moves all odd elements values to the front (if any exist), otherwise
preserve the order of the elements.
• Method containDuplicate: returns true if the array contains duplicate elements (not necessary to
be adjacent).

Sometimes we need to implement bigger values. Create a class BigNumber that uses a 40-element array of digits to store integers as large as 40 digits each. Provide methods Input, ToString, Addand Subtract. For comparing BigNumber objects, provide the following methods: IsEqualTo,IsNotEqualTo, IsGreaterThan, IsLessThan, IsGreaterThanOrEqualTo and IsLessThanOrEqualTo. Each ofthese is a method that returns true if the relationship holds between the two BigNumber objects andreturns false if the relationship does not hold. Provide method IsZero. In the Input method, use thestring method ToCharArray to convert the input string into an array of characters, then iterate throughthese characters to create your BigNumber.

It starts off with 52 cards, but as cards are dealt from the deck. the number of cards becomes smaller. The class has one private instance variable that stores the Cards that are currently in the Deck: private Card] carde; Important Note: The first Card in the array will be considered the card that Is at the top of the deck. Whon cards aro removed from the deck they will be removed from the front of the array. You must implement the flollowing methods for the Deck class: • public Dock) This constructor initializes the Deck with 52 card objacts, representing the 52 cards that are in a standard deck. The cards must be ordered as in the diagram below: Important: The FIRST card in your array should be the Ace of Spades, and the LAST card should be the King of Diamonds. Note that in the picture below, the Ace of Spades is at the TOP of the deck, which is to the left.

Write classes in an inheritance hierarchy Implement a polymorphic method Create an ArrayList object Use ArrayList methods For this, please design and write a Java program to keep track of various menu items. Your program will store, display and modify salads, sandwiches and frozen yogurts. Present the user with the following menu options: Actions: 1) Add a salad2) Add a sandwich3) Add a frozen yogurt4) Display an item5) Display all items6) Add a topping to an item9) QuitIf the user does not enter one of these options, then display:Sorry, <NUMBER> is not a valid option.Where <NUMBER> is the user's input. All menu items have the following: Name (String) Price (double) Topping (StringBuilder or StringBuffer of comma separated values) In addition to everything that a menu item has, a main dish (salad or sandwich) also has: Side (String) A salad also has: Dressing (String) A sandwich also has: Bread type…arrow_forwardJava programming help please. Main and other class of code is below. Thank you so so much. i have to Write a program that does the following: You have an array of integers with positive and negative values. using one ourArray object (will post code of "ourArrary" below) , and in two loops maximum, How can you reorganize the content of the array so that all negative numbers are on one side and the positive numbers are on the other side. [-3, 2, -4, 5, -6, -8,-9, 7, 13] The output should be [-3, -4, -6, -8, -9, 2, 5, 7, 13] Our array code: public class ourArray<T> implements iQueue{ private T[] Ar; private int size = 0; private int increment = 100; //default constructor @SuppressWarnings("unchecked") public ourArray () { Ar = (T[]) new Object[100]; size = 0; } //constructor that accepts the size @SuppressWarnings("unchecked") public ourArray (int n) { Ar = (T[]) new Object[n]; size = 0; } //constructor that specifies the initial capacity and the increment…arrow_forward
