🤷🏻‍♂️ Why ? What is wrong ?

Does anyone see what the problem is? It took me a long time to do this and I don't want to let go. :)

When i run my code IntelliJ doesn't show results. it happens only on codegym task when I start my own project everything looks fine.

Wykonałem zadanie które nie zostało sprawdzone przez błąd kompilatora, co to jest i jak to naprawić?
