Error when verifying

Question about the task

Under discussion

When I press verifiy it just says UNKNOWN-ERROR. Help

package en.codegym.task.pro.task03.task0306;

import java.util.Scanner;

/*
Triangle
*/

public class Solution {
    private static final String TRIANGLE_EXISTS = "It's a triangle";
    private static final String TRIANGLE_DOES_NOT_EXIST = "It's not a triangle";

    public static void main(String[] args) {
       Scanner scanner = new Scanner(System.in);
       int num1 = scanner.nextInt();
       int num2 = scanner.nextInt();
       int num3 = scanner.nextInt();

       if (num1 >= num2 + num3 || num2 >= num1+num3 || num3 >= num1+num2 ){
           System.out.println(TRIANGLE_DOES_NOT_EXIST);
       }
       else {
            System.out.println(TRIANGLE_EXISTS);
       }
    }
}

Let's write a program that will calculate the possibility of the existence of a triangle based on the lengths of sides.
To do this, you need to:

Enter three numbers from the keyboard — the lengths of the sides of the assumed triangle.
Use the lengths of the sides to determine whether a triangle is possible.

Depending on the result, display "It's a triangle" or "It's not a triangle".

To make this determination, you need to compare each side with the sum of the other two sides.
That is, you will need to perform three comparisons:

If each comparison indicates that the side is less than the sum of the other two sides, then a triangle with these sides does exist.
If even one comparison indicates that the side is greater than or equal to the sum of the other two sides, then a triangle with these sides does not exist.

Requirements:

The program should read three number from the keyboard.
The program should display text on the screen in accordance with the task conditions.
If a triangle with the entered sides is possible, then you need to display "It's a triangle".
If a triangle with the entered sides is not possible, then you need to display "It's not a triangle".

package en.codegym.task.pro.task03.task0306; import java.util.Scanner; /* Triangle */ public class Solution { private static final String TRIANGLE_EXISTS = "It's a triangle"; private static final String TRIANGLE_DOES_NOT_EXIST = "It's not a triangle"; public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int num1 = scanner.nextInt(); int num2 = scanner.nextInt(); int num3 = scanner.nextInt(); if (num1 >= num2 + num3 || num2 >= num1+num3 || num3 >= num1+num2 ){ System.out.println(TRIANGLE_DOES_NOT_EXIST); } else { System.out.println(TRIANGLE_EXISTS); } } }

I guess the error is in the 13th line of your code public static void main (String args [] ){} this is how it should be your placement of square brackets is wrong

you need to put each of the sum in paranthesis(). separate each of the three expressions with paranthesis()

I had that too. I think it's a bug.
