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.

OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

7. 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.
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.
