Triangle Validity Check

Check if three sides can form a valid triangle using triangle inequality.

Java

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter side a: ");
        int a = sc.nextInt();
        System.out.print("Enter side b: ");
        int b = sc.nextInt();
        System.out.print("Enter side c: ");
        int c = sc.nextInt();

        if (a + b > c && a + c > b && b + c > a) {
            System.out.println("Triangle is Valid");
        } else {
            System.out.println("Triangle is Not Valid");
        }

        sc.close();
    }
}

Output

Enter side a: 3
Enter side b: 4
Enter side c: 5
Triangle is Valid

We use the triangle inequality theorem: sum of any two sides must be greater than the third side.
