what is wrong here ?

Question about the task

Rule of the triangle

Java Syntax, Level 4, Lesson 4

Under discussion

not sure why last condition failed .... any help please?

Use the keyboard to enter three numbers a, b, and c (the lengths of the sides of the proposed triangle).
Determine whether a triangle with these sides can exist.
Display the result as follows:
"The triangle is possible." - if a triangle with these sides could exist.
"The triangle is not possible." - if a triangle with these sides cannot exist.

Hint:
A triangle can exist only if the sum of two of its sides is greater than the third side.
You need to compare each side with the sum of the other two.
If even one side is larger or equal to the sum of the other two sides, then no such triangle exists.

Requirements:

The program should read three numbers from the keyboard.
The program should display text on the screen according to the task conditions.
If a triangle with the specified sides could exist, you need to display: "The triangle is possible."
If a triangle with the specified sides cannot exist, you need to display: "The triangle is not possible."

package com.codegym.task.task04.task0415; /* Rule of the triangle */ import java.io.*; import java.util.Scanner; public class Solution { public static void main(String[] args) throws Exception { //write your code here Scanner scan = new Scanner(System.in); int a = scan.nextInt(); int b = scan.nextInt(); int c = scan.nextInt(); if ((a + b) >c ){ if ((a + c ) > b){ if ((c + b) > a){ } }System.out.println("The triangle is possible."); }else{ System.out.println("The triangle is not possible."); } }}

if sum of any two sides is greater than 3rd side you should write if statement like this :

if ((a + b) >c ||  (a + c ) > b || (c + b) > a){ possible}
else { not possible}

Thank you that helps but instead OR should be AND ...
