1. Define a class Circle, which is-a Shape and contains following unique data/methods:

Data: radius (double);

Two constructors:

public Circle(double radius)

public Circle (double radius, String color, boolean filled)

Getter and Setter methods for radius

Methods to calculate area and perimeter

getArea()

getPerimeter()

toString() that returns "(Filled/Unfilled) circle with color = ?, radius = ?, area = ?, perimeter = ?". (You should override the Shape's toString() method; call getArea() and getPerimeter() methods to get area and perimeter )

2. Define a driver class (with main method) called TestCircle to test the class Circle. You are asked to create two circle objects: one is with radius 1.0; the other one is a red filled circle with radius 3.0. Print out both circles information.

3. Define another class Rectangle, which is-a Shape and contains following unique data/methods:

Data: length (double), width (double);

Two constructors:

public Rectangle(double length, double width)

public Rectangle(double length, double width, String color, boolean filled)

Getter and Setter methods for length and width

Methods to calculate area and perimeter

getArea()

getPerimeter()

toString() that returns "(Filled/Unfilled) Rectangle with color = ?, length = ?, width = ?, area = ?, perimeter = ?". (You should override the Shape's toString() method; call getArea() and getPerimeter() methods to get area and perimeter )

4. Define a driver class (with main method) called TestRectangle to test the class Rectangle. You are asked to create two rectangle objects: one is with width 1.0 and length 1.0; the other one is a blue unfilled rectangle with width 3.0 and length 5.0. Print out both rectangles information.
