triangle isnt possible not getting executed

Question about the task

Under discussion

i have added the code when triangle is possible and added else with the conditions mentioned when triangle isnt possible .. how to get the text printed for triangle isnt possible

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.*; public class Solution { public static void main(String[] args) throws Exception { //write your code here BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String x= reader.readLine(); int a=Integer.parseInt(x); String y= reader.readLine(); int b = Integer.parseInt(y); String z= reader.readLine(); int c= Integer.parseInt(z); if (((a+b)>c)||((b+c)>a)||((c+a)>b)){ System.out.println("The triangle is possible."); } else if(((a>=(b+c))||(b>=(a+c))||(c>=(a+b)))){ System.out.println("The triangle is not possible."); } } }

You should change the or(||) operator to and(&&) operator...it will work...Because if the triangle exists then all of its sides must satisfy the sum rule But if we use or(||) then it will be True even if any one of its side satisfies the sum rule

If even one side (you have to compare ALL sides) is larger or equal to the sum of the other two sides, then no such triangle exists that in math is call "triangle inequality theorem". Example: 2, 3, 4 (a, b, c) 2 + 3 = 5 and 5 > 4 => True (a + b) > c 2 + 4 = 6 and 6 > 3 => True (a + c) > b 3 + 4 = 7 and 7 > 2 => True (b + c) > a ALL the conditions of the triangle inequality are satisfied, thus triangle with sides 2, 3 and 4 is possible. In the example of 4,1,1 (a,b,c) 4 + 1 = 5 and 5 > 1 => True (a +b) > c 4 + 1 = 5 and 5 > 1 => True (a + c) > b 1 + 1 = 2 and 2 > 4 => False (b + c) > a Hence, ALL the conditions of the triangle inequality theorem are not satisfied, thus triangle with sides 4, 1 and 1 is not possible. You have to change the "or" || because you don't validate all the conditions, and put "and" && to validate ALL the conditions.
