Write a class Circle.java from which we can instantiate a circle by giving

its radius and use it as is shown in the following program.

1 import java.util.Scanner;

2 public class Circles {

3 public static void main(String[] args) {

4 Scanner input = new Scanner(System.in);

5 System.out.print("Enter radius: ");

6 double radius = input.nextDouble();

7 input.close();

8 Circle myCircle = new Circle(radius);

9 double area = myCircle.getArea();

10 double perimeter = myCircle.getCircumference();

11 System.out.printf("Area: %.2f, Perimeter: %.2fn", area,

perimeter);

12 }
