Question

(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. Enter three sizes, separated by spaces(decimals values are acceptable): 4.5·5.5·3.5 A triangle could measure 4.50, 5.50, by 3.50.

Answer 1

import java.util.Scanner;

public class TriangleCheck {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double a, b, c;

        System.out.println("Enter three sizes, separated by spaces(decimals values are acceptable): ");
        a = scanner.nextDouble();
        b = scanner.nextDouble();
        c = scanner.nextDouble();

        if (a + b <= c || a + c <= b || b + c <= a){
            System.out.printf("A triangle could NOT measure %.2f, %.2f, by %.2f.",a,b,c);
        }
        else{
            System.out.printf("A triangle could measure %.2f, %.2f, by %.2f.",a,b,c);
        }
        System.out.println();
    }
