Java

Consider the following class declaration of Circle class:

public class Circle { private double radius; public Circle(double r) { radius = r; } public double getArea() { return Math.PI * radius * radius; } public double getRadius() { return radius; } } 

Write a toString method for this class. The method should return a string containing the radius and area of the circle.

Write an equals method for this class. The method should accept a Circle object as an argument. It should return true if the argument object contains the same data as the calling object, or false otherwise.

Write a greaterThan method for this class. The method should accept a Circle object as an argument. It should return true if the argument object has an area that is greater than the area of the calling object, or false otherwise.
