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.
