Create a new project for this program called TestOldMaid and add a class with a main() method.
In the project:
Copy your Deck and Card class from the earlier project into it.
Create a subclass of Deck called OldMaidDeck. It is special because one of the Queens is missing so it only has 51 cards. Create a constructor method that calls the super class constructor, then removes a queen. Override the toString method so it returns the name of the deck and the number of cards in it.
Write the test main() method. Create an OldMaidDeck object and deal all the cards to six players. It is ok if not everyone has an equal number of cards. Use arrays or ArrayLists for the players hands.
Show the hands of all 6 players.
Refer to the web to find out more about the Old Maid card game: https://bicyclecards.com/how-to-play/old-maid/
Fully document all classes with your name, date and description. And each data member and method is documented. Each block that does something is also documented.

Write a new method for the atom class called ision that will return true or false, depending upon whether the atom is an ion. An atom is an ion if it is charged (i.e., if the number of electrons ≠ the number of protons).

- Can you implement the Student class using the concepts of encapsulation? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. You are given a Student class in the editor. Your task is to add two fields: ● String name ● String rollNumber and provide getter/setters for these fields: ● getName ● setName ● getRollNumber ● setRollNumber Implement this class according to the rules of encapsulation. Input # Checking all fields and getters/setters Output # Expecting perfectly defined fields and getter/setters. There is no need to add constructors in this class.arrow_forwardTake a look at the header of the method below, and then implement a sample call to it in your code.empty public ShowValue ()arrow_forwardPlease help me create a cave class for a Hunt the Wumpus game (in java). You can read the rules in it's entirety of the Hunt the Wumpus game online to get a better idea of the specifications. It's an actual game. INFORMATION: The object of this game is to find and kill the Wumpus within a minimum number of moves, before you get exhausted or run out of arrows. There is only one way to win: you must discover which room the Wumpus is hiding in and kill it by shooting an arrow into that room from an adjacent room. The Cave The Wumpus lives in a cave of 30 rooms. The rooms are hexagonal. Each room has up to 3 tunnels, allowing access to 1, 2 or 3 (out of 6) adjacent rooms. The attached diagram shows the layout of rooms in the cave. The map wraps around such that rooms on the edges (white cells) have neighbors from the opposite edge (blue cells). E.g., the neighbors of room 1 are rooms 25, 26, 2, 7, 6, and 30, and you could choose to connect room 1 to any of these rooms. Observe how…arrow_forward
- Please use Java to help me with the assignment below. The assignment: A microwave control panel has four buttons: one for increasing the time by 30 seconds, one for switching between power levels 1 and 2, a reset button, and a start button. Implement a class that simulates the microwave, with a method for each button. The method for the start button should print a message “Cooking for ... seconds at level ...”.arrow_forwardThis is for pygame Ball Class: The Ball class inherits from Drawable and it will draw a circle at its current location. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable Classarrow_forwardAdd a method called multiplesOfFive to the Exercise class. The method must have a void return type and take a single int parameter called limit. In the body of the method, write a while loop that prints out all multiples of 5 between 10 and limit (inclusive) on a single line. For instance, if the value of limit were 15 then the method will print: 10 15 You can use the printEvenNumbers method that is already in the Exercise class as an example to help you work out how to complete this method. In the main method of the Main class, add a call on the Exercise object to your multiplesOfFive method that prints the multiples of 5 between 10 and 25. Add a method called sum to the Exercise class. The method must have a void return type and take no parameters. In the body of the method, write a while loop to sum the values 1 to 10 and print the sum once the loop has finished. In the main method of the Main class, add a call on the Exercise object to your sum method. Check that it prints: 55 Add…arrow_forward
- Exercise 1 - Number Guessing Game Make a new Java Project called Lab2. Within it, add a new class with the main method called NumberGuessGame. Inside the main method, implement a number guessing game, which will work by generating a pseudorandom number in the range of 0 to 100 (inclusive, so both 0 and 100 should be possible), then asking the user to enter a number that will be their guess. If the two match, display an appropriate message. Otherwise, display either "greater" or "lesser", depending on whether the pseudorandom number is greater than or less than the number entered.arrow_forwardWrite a class for a Chicken that also implements your interface. The Chicken’s type will be “chicken” and the sound will vary. About 50% of the time, the chicken will say “bawk!” and other times it will say “cluck!”.arrow_forwardcheck the Coin class and cointester program below. Write a new method .flipCoins(), that flips two (2) coins: the current coin and the coin passed as a parameter. The method returns the integer addition of the flipSides of both coins. Example, as if used in the CointTester program class:Coin bobCoin = new Coin(); // create Coin object [using Coin() constructor]Coin aliceCoin = new Coin(6); // create Coin object with 6 sidesint combinedFlip = 0; // combined flip value of two coinscombinedFlip = bobCoin.flipCoins(aliceCoin); // flip both coins, returned combinedSystem.out.println ("Flip of two coins: " + combinedFlip); Coin class: import java.util.Random; blic class Coin{private int numSides = 2; private int flipSide = 0;private static int coinCounter = 0; private int uniqueID; /** default constructor for Coin class*/public Coin (){coinCounter++;uniqueID = coinCounter; }/** constructor that sets the sides for Coin class* @param numSides the number of sides of the coin*/public Coin…arrow_forward
- Write a program that simulates the Magic 8 Ball game. The class should have a method that returns an answer at random. Test your class by outputting the answer several times.arrow_forwardWrite a method that takes two string parameters, and tells whether the first is a substring of the second. You can't use framework methods that do this for you, such as indexOf(). In other words, you have to write the loops yourself. But, you can use the primitive methods such as charAt(). Also analyze the program's performance and state the big-O complexity of your method. Provide a screenshot of the code working.arrow_forwardThis is for pygame Text Class The Text class inherits from Drawable and it will be used to display the player’s score. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable Classarrow_forward
