• Always use variables instead of hardcoded values.
• Add comments.
• Format the program properly e.g. indentation, brackets line up, etc. similar to the book examples.
• Instance variables should be declared as private

Problem Description: Circle Class Note: - Create two separate java files, one for the Circle class and the other containing main method. - All fraction values should be formatted to two decimal places. 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. area. Returns the area of the circle, which is calculated as area = PI * radius * radius . . diameter. Returns the diameter of the circle, which is calculated as diameter = radius * 2 . circumference. 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
