1. Design an abstract class named Polygon that contains: a. A private String data field named color (default "white") b. A private boolean data field named filled (default false) c. The accessor and mutator methods for color and filled. d. The following an abstract method: public abstract double getArea(); public abstract double getSides(); e. Create a subclass Triangle, Rectangle that extends the Polygon class and implement the following: f. Create a private double data field named base, height. g. A constructor that initializes the base and height fields. h. The accessor and mutator methods for base and height. i. Implement the getArea() method to return the area of Triangle. j. Implement the getSides() method to return the side of Triangle. k. Create a Triangle and Rectangle objects and show the state of each object Programs Set-2 1. Write a program in Java that performs following tasks: a. Creates a class called Person having attributes personName,personID. b.
