In java language on netbeans design a console application that will print the game sales for a particular game in 2021. Use an abstract class named Games that contains variables to store the game name, game genre and the total sales. Create a constructor that accepts the game name, game genre and the total game sales as parameters. In this class also create get methods for the variables. The Games class must implement an iGames interface that contains the following: public interface iGames { public void printSales(); public String getGame(); public String getGameGenre(); public int getGameSales(); } Create a subclass called Game Sales that extends the Games class. The Games Sales class must contain a constructor to accept the game name, game genre and total game sales as parameters. Then, write code for the Print Sales method, which prints the game sales report for 2021. Finally, write a Use Games class to instantiate the Games Sales class.
Garbage collector works in following condition: 1.Employee john = new Employee()john=null; 2.Employee c1 =new Employee()Employee c2 = new Employee()c1=c2; 3.new Employee(); //anonymous object Please create a class /classes in java which contains examples related to above 3 conditons.
Design/code/test a Java program containing an abstract the class absWelcome. This class should contain: 1. A public abstract void method (you name it) that is empty 2. A public regular method (you name it) that prints "Welcome to " Next, create a subclass clsHello that extends absWelcome. This class should contain: • A public regular method (you name it) that prints "Java Programming" Finally, inside the Main class create an object (you name it) from the clsHello class. Use this new object reference to: 1. Output "Welcome to " from the abstract class 2. Output "Java Programming" from the subclass Your output should resemble that shown below >sh -c javac -classpath -type f-name '*.java') java -classpath :targe Welcome to Java Programming
When a method in a subclass overrides a method in superclass, it is still possible to call the overridden method using super keyword. If you write super.func() to call the function func(), it will call the method that was defined in the superclass. You are given a partially completed code in the editor. Modify the code so that the code prints the following text: Hello I am a motorcycle, I am a cycle with an engine. My ancestor is a cycle who is a vehicle with pedals. import java.util.*;import java.io.*; class BiCycle{String define_me(){return "a vehicle with pedals.";}} class MotorCycle extends BiCycle{String define_me(){return "a cycle with an engine.";}MotorCycle(){System.out.println("Hello I am a motorcycle, I am "+ define_me()); //////code hereString temp=define_me(); //Fix this line and code here/////code ends here System.out.println("My ancestor is a cycle who is "+ temp );}}class Solution{public static void main(String []args){MotorCycle M=new MotorCycle();}}

public class Cat { private int age; public Cat (int a) { age = а; } public int getAge() { return a; } } Which of the following best explains why the getAge method will NOT work as intended? The instance variable age should be returned instead of a, which is local to the constructor. The variable age is not declared inside the getAge method. The getAge method should be declared as private. The getAge method should have at least one parameter.
When a class implements an interface with default methods and overrides them, the class inherits the default methods’ implementations. An interface’s designer can now evolve an interface by adding new default and static methods without breaking existing code that implements the interface. State whether the statement is true or false. If false, explain why.
