Ivan You need a main method to execute your code. So write another class: public class TestClass{ public static void main(String[] args){ //here you do all the stuff you want to do with the other classes } }

Your code has no main method this is needed as a starting point for your program to run

I structured your code a bit. You need to rework both toString() methods. https://code.sololearn.com/cznxQeT4b29T/?ref=app

No, you don't need to rewrite anything. Just add another class that contains the main method. It would be best if you save your code in the code playground and share the link here. It would also be helpful to explain your other classes as I don't speak polish. ;) I can look at it tomorrow afternoon/evening.
