N JAVA Write a class Store which includes the attributes: store name, city. Write another class encapsulating an Art Gallery, which inherits from Store. An Art Gallery has the following additional attributes: how many paintings are sold every year and the number of artists submitting artwork. Code the constructor, accessors, mutators, toString and equals method of the super class Store. Code the constructor, accessors and mutators for the subclass Art Gallery. In the Art Gallery class, also code a method returning the average number of paintings per artist.

‏java programming Robot Class : a robot has a name , located at a point with integer coordinates , faces north , east , south , or west and keeps a record of all its movements positions . The class has the following methods : A default constructor that initializes robot's name to " Unknown ” , location to ( 0,0 ) , direction to North , and travelled distance to 0 , and simulated movements to null . A constructor that given robot's name , starting location , and facing direction , Accessor methods to access all the instance variables and the simulated movements of the robot Mutator methods that change the instance variables to given values and they made the change for only suitable values . tumLeft and turn Right methods that change the direction of the robot but not the location move method that moves the robot by one unit in the direction it is facing . get Travelled Distance method that retums how many units has the robot moved .

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

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.
