Java classes throwing a permanent error

Permanent error in class Java

I wrote the code and when I run it, all the time there is an error in different parts. I’m currently running into an error here: public class GuessGame { Player p1; Player p2; Player p3; public void startGame(){ p1 = new Player(); p2 = new Player(); p3 = new Player(); } } I do not understand what the problem is and how to avoid such errors, what affects them? And what other services are there for code analysis? I want to check it in the process, and not see its errors at startup.
