Step by step
Solved in 3 steps with 5 images
- Create a project to play a bunch of games. Add a class that has main() in it. Create an abstract class called Game. Define one instance variable for the name of the game. Define a constructor that takes the name of the game as a parameter and sets it. Define an abstract method called playGame. It takes no arguments and returns void. Create a child class of Game called BoardGame. Rather than implementing playGame, declare BoardGame abstract. Create a child class of BoardGame called Chess or Battleship or Monopoly or whatever board game you want. Implement the playGame with only a message that says the name of the game and that it is being played. Create a child class of Game called CardGame. Rather than implementing playGame, declare CardGame abstract. Create a child class of CardGame for War. Implement the playGame method by with a message that says the game of war is being played. Create a child class of Game called VideoGame. Rather than implementing playGame,…1. Design a new Triangle class that extends the abstract GeometricObject class. Draw the UML diagram for the classes Triangle and GeometricObject then implement the Triangle class. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides, and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.using java programmingCreate abstract class Pet , which is the abstract superclass of all animals. Declare a integer attribute called legs, which records the number of legs for this animal. Define a constructor that initializes the legs attribute. Declare an abstract method eat. Declare a concrete method walk that prints out something about how the animals walks (include the number of legs). Create the Dog class. The Dog class extends the Pet class. This class must include a String attribute to store the name and food of the pet Define a default constructor that calls the superclass constructor to specify that all dogs have 4 legs and name. override the eat and walk method. Create the Cat class that extends Pet. This class must include a String attribute to store the name of the pet, and a string to save food . Define a constructor that takes one String parameter that specifies the cat's name and food. This constructor must also call the superclass constructor to specify that all cats have four legs.…
- In Java: Implementing a Superclass Employee Part 1: Implement a superclass Employee that has the following fields and methods. Fields: string firstName string lastName int employeeID double salary Methods: constructor method - initialize salary field to zero. setters and getters for firstName, lastName, and employeeID employee Summary method - prints all account attributes Part 2: Implement a Manager class that inherits from the Employee class. Fields: string department a Methods: employeeSummary method - prints all superclass and subclass attributes Ensure that your program has the two required classes and a test class.Create abstract class Pet , which is the abstract superclass of all animals.

- Create a class student and then create an object of this class and work with it. Idfirst namelast namegradesdate of birthfield of studyenrolled coursesenrolled semester using constructors, setters-getters in JAVA programmingID must be generatedJava programing ShipsStudy the UML diagram carefully. The green spots signify public. The red squares signify private. Superclass Ship is abstract because it contains the abstract method purpose. This class also implements the Comparable interface to compare ships by tonnage. Ship also has a public static integer named numShips that is incremented in the constructor to serve as a counter for the number of ships.After coding these classes, write a program named TestShips that uses them as follows:⦁ Create an array of declared type Ship that contains at least six ships (two of each concrete subclass). You can make up all of the values for the data members of each ship.⦁ The Strings returned by purpose() can be determined by viewing the Possible Output below.⦁ Process the array in an enhanced for loop to display for each ship:⦁ The actual type using the getClass() method inherited from class Object.⦁ The output of the toString() method.⦁ The value returned by the purpose()…This assignment requires one project with two classes.

Implement a MovieTest class to test the class Movie you just created.• Create two Movie objects: one using the no-args constructor and one from theconstructor with all fields.• Print the contents of both objects. Please submit a screenshot. Hint: toString()method.Test time left: 01:48:45 Q3. Write a Java program to implement the concept of run time polymorphism through method overriding with the following scenario. There are three music companies Tips, Zee and T series. These companies use a super class Music, where there is a constructor for initializing music and play() method to play music. Create subclasses Tips, Zee and Tseries that overrides a play() method in the super class and add some new functionality to it. You can use print statement in the body of the constructor and method of the class.T/F1. Interface classes cannot be extended but classes that implement interfaces can be extended.
