JAVA

Write a Circle class that has the following fields:

radius:

a double PI:

a double initialized with the value 3.14159

The class should have the following methods:

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

setRadius. A method that stores a value in a field getRadius.

A method to get a value from a class's field getArea.

Returns the area of the circle, which is calculated as area = PI x radius x radius getDiameter.

Returns the diameter of the circle, which is calculated as diameter = radius x 2 getCircumference.

Returns the circumference of the circle, which is calculated as circumference = 2 x PI x 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.

Sample Run:

Enter Radius: 15

Area of the Circle: 706.85775

Diameter of the Circle: 30.0

Circumference of the Circle: 94.2477
