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!

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.");
}
}
}
