Circle Class Write a Circle class that has the following fields:

• radius : a double

• PI : a final double initialized with the value 3.14159

The class should have the following methods:

• Constructor . Accepts the radius of the circle as an argument.

• Constructor . A no-arg constructor that sets the radius field to 0.0.

• setRadius . A mutator method for the radius field.

• getRadius . An accessor method for the radius field.

• getArea . Returns the area of the circle, which is calculated as area = PI * radius * radius

• getDiameter . Returns the diameter of the circle, which is calculated as diameter = radius * 2

• getCircumference . Returns the circumference of the circle, which is calculated as circumference = 2 * PI * radius

Write a program that demonstrates the Circle class by asking the user for the circle’s radius, creating a Circle object, and then reporting the circle’s area, diameter, and circumference.
