I wrote a code. After many trials I was pretty sure that is ok so I verify it. It passed, task was completed. But still... the program doesnt work! I run it and after wrote 10 Strings an output is like "3", "5", sometimes its empty. I reinstall InteliiJ, but still something is wrong although solution is fine (I download correct solution from codegym to compare my code and correct code). Anybody has idea why it is like that? I paste the code it into NetBeans and it works fine. Why the same code doesnt work on InteliiJ?
