Question

JAVA

Write code which takes two inputs from the user, a number of sides followed by a side length, then creates a regular polygon with that number of sides and side length.

Sample run:

Type the number of sides:

8

Type a side length:

7.5

regular octagon with side length 7.5

Hint: Make sure you use the right data types when taking user input.

Answer 1

import java.util.Scanner;

public class CreatePolygon {
        public static void main(String[] args) {
                Scanner sc = new Scanner(System.in);
                System.out.println("Type the number of sides:");
                int sides = sc.nextInt();
                System.out.println("Type a side length:");
                double length = sc.nextDouble();
                switch (sides) {
                case 5:System.out.println("regular octagon with side length "+length);break;
                case 6:System.out.println("regular hexagon with side length "+length);break;
                case 7:System.out.println("regular heptagon with side length "+length);break;
                case 8:System.out.println("regular octagon with side length "+length);break;
                case 9:System.out.println("regular nonagon with side length "+length);break;
                case 10:System.out.println("regular decagon with side length "+length);break;
                case 12:System.out.println("regular dedecagon with side length "+length);break;
                        
                }
        }
}
