I genuinely need help on the Rule of the triangle or a hint will do

Question about the task

Resolved

I have tried the "Rule of the triangle" several times in several ways but still I get errors. I will appreciate anyone that will point me towards the right direction, because I know the error exists in the condition section but I just can't figure it out.

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 { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); int a = Integer.parseInt(reader.readLine()); int b = Integer.parseInt(reader.readLine()); int c = Integer.parseInt(reader.readLine()); if(a>=(b+c) && b>=(a+c) && c>=(b+a)){ System.out.println("The trianlge is not possible."); }else{ System.out.println("The trianlge is possible."); } } }

solution

"two of its sides is greater than the third side" (it is greater than and not greater than or equal to) Right now your code checks to see if the third side is greater than the two other sides. This is backwards from what the requirements say. As it stands, the only three numbers that would return true for that 'if' statement would be 0, 0, 0. Any other three numbers would fail and it would output "The trianlge is possible.".

I am still seeing failure for this. Could you help me out public class Solution { public static void main(String[] args) throws Exception { //write your code here BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); int a = Integer.parseInt(br.readLine()); int b = Integer.parseInt(br.readLine()); int c = Integer.parseInt(br.readLine()); if(a>(b+c) && b>(a+c) && c>(b+a)){ System.out.println("The triangle is not possible."); }else{ System.out.println("The triangle is possible."); } } }
