class Point with instance variables as: xCoordinate(int) and yCoordinate(int). Write public instance methods (getters & setters) for each instance variable. Now, write a class Circle with private instance variables as radius and Pi (value is 3.14). Write public setter, getter for radius, Area method for calculating Area, Draw method for radius.

Formula for calculating area=pi*r^2
Formula for calculating radius=Math.sqrt(xCordinate^2+yCordinate^2)

Extend a Circle class from Point class such as Class Circle extends Point
Write a Default constructor in Circle class that sets radius, xCoordinate&yCoordinate to some default value e.g. -1;
Write a Parameterized constructor in Circle class which takes xCoordinate, yCoordinate and radius as a parameter. E.g.

Circle (int xCoordinate, int yCoordinate, double radius) {

this.xCoordinate= xCoordinate;

this.yCoordinate= yCoordinate;

this.radius=radius;

}

Now write a ColoredCirlce class with private instance variable as color (String) and public setter & getters. Extend the ColoredCirclefrom Circle and do the following operations.
