LAB circle and Circle Driver

Create a java class Circle as described below:

radius: a double
PI: a final double initialized with the value 3.14159
The class should have the following methods:

calculateArea - Returns the area of the circle, which is calculated as:
area = PI * radius * radius
calculateDiameter - Returns the diameter of the circle, which is calculated as:
diameter = radius * 2
calculateCircumference - Returns the circumference of the circle, which is calculated as:
circumference = 2 * PI * radius
setRadius - A mutator (setter) method for the radius field
getRadius - An accessor (getter) method for the radius field

Create test data and calculate the expected result.

Write a program name CircleDriver 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.
