write program in java Design an abstract class GeometricObject. GeometricObject must ensure that its children must implement calcArea() method. Design RectangleYourRegNo and CircleYourName Classes as children of GeometricObject class with overridden toString() method to return “Rectangle with w Width and h Height is drawn” OR “Circle with r Radius is drawn”. The attributes of Rectangle are length, width. The attribute of Circle is radius Hint: Area of circle=πr2 , Area of rectangle= width*length
Let’s build a Player Portfolio System that has an abstract class. Create a new Player Abstract class. Implement getName method in this abstract class. Define other methods as abstract. Here is an example: abstract class PlayerA {private String name;public String getNameA(){return name;}public PlayerA(String name) {this.name = name;}abstract public int getStatsA();abstract public String getSportA();} Create NFL Player and NBA Player concrete classes that will extend Player abstract class. Create a main method to implement your classes
Let’s build a Player Portfolio System that has abstract classes. Inheritance using Abstract: Create a new Player Abstract class. Implement getName method in this abstract class. Define other methods as abstract. Here is an example: Abstract class PlayerA {private String name;public String getNameA(){return name;}public PlayerA(String name) {this.name = name;}abstract public int getStatsA();abstract public String getSportA();} Create NFL Player and NBA Player concrete classes that will extend Player abstract class. Think of meh=thods for these two classes and implement them Develop appropriate unit tests.

Given the following class. (JAVA) public class FamilyMember { public String drink( ) {return “cup”;} public String eat( ) {return “fork”;} } Write a Baby class that is derived from the FamilyMember class. The Baby class has an instance variable for the age, a default constructor, and a constructor that accepts an integer. Include any other necessary methods. If a baby is older than 3 years, print that “it eats with its fork”; otherwise, “it eats with its hands”.

Write a class named Person with data attributes for a person’s name, address, and telephone number. Next, write a class named Customer that is a subclass of the Person class. The Customer class should have a data attribute for a customer number and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Demonstratean instance of the Customer class in a simple program.
