Question

Write a java code for a concrete class called Circle based on the following specification:

The class should have one member variable called radius of type double
The class should have appropriate constructor.
The class should have an equals method. Define two Circle objects to be equal if they have the same radius (Circle one is less than Circle two if the radius of Circle one is less than the radius of Circle two. The two Circles are equal if they have the same radius. Circle one is larger than Circle two if its radius is larger).
The class should have a method called findArea (area = pr2).
The class should have a method called findCircumference (circumference = 2pr).
The class should have a toString method. This method should construct a String containing the radius, area, and perimeter of the circle. For example Radius: 1 Area: 3.14159 Circumference: 6.28318.
The class should implement the Comparable interface. Circle one is less than Circle two if the radius of Circle one is less than the radius of Circle two. The two Circles are equal if they have the same radius. Circle one is larger than Circle two if its radius is larger. If circle One.compareTo circle Two <> 0
