Error with input code

Question about the task

Rule of the triangle

Java Syntax, Level 4, Lesson 4

Resolved

I can't seem to get my input codes right for my last two task. Its giving me this error

But it works on Intelli J I DEA. However on Intelli J IDEA, I can't run any current task. Anytime i click run Task03\03 ends up running no matter what I do. Coding today had been frustrating. Help needed!

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 side1 = reader.readLine(); String side2 = reader.readLine(); String side3 = reader.readLine(); int a = Integer.parseInt(side1); int b = Integer.parseInt(side2); int c = Integer.parseInt(side3); if (a>b+c || b>a+c || c>a+b) { System.out.println("The triangle is not possible."); } else if (a+b>c || b+c>a || a+c>b) { System.out.println("The triangle is possible."); } } }

Here import import java.util.*; is missing.

useful

if(a+b > c && a+c>b && b+c>a){ System.out.println("The triangle is possible."); }else{ System.out.println("The triangle is not possible."); } This should do the trick!!!

solution

The online compiler through code gym is too basic to use for tasks past the first couple levels, only use intelliJ. As for it running the wrong task, right click anywhere in your typed code and select run solution from that menu. As far as I can tell, the code gym tasks are interpreted in Intellij as one large program, and when you click the run button at the top it will start the last main method that was run.

As for it not verifying, try this instead:

if (a>=b+c || b>=a+c || c>=a+b)
    System.out.println("The triangle is not possible.");
else
    System.out.println("The triangle is possible.");
