Question

For JAVA- Write an application that reads three nonzero values entered by the user and determines and prints whether they could represent the sides of a triangle.

Answer 1

import java.util.Scanner;

public class ValidateTriangle {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.println("Please enter the sides of the triangle, separate by a space.");
        int s1 = in.nextInt();    // read first length
        int s2 = in.nextInt();    // read second length
        int s3 = in.nextInt();    // read third length

        if(s1+s2 > s3 && s2+s3 > s1 && s1+s3 > s2) {   // if triangle is valid
            System.out.println("Yes, this is a valid triangle.");
        } else {    // if triangle is not valid
            System.out.println("This is not a valid triangle.");   // report that to user
        }
    }
}
