One java file can only have one public class <ClassName>.
For your case, you basically you need 3 java files.
- GuessGame.java
- Player.java
- GameLauncher.java

So don't put everything into one file.

Welcome to JavaRanch! (Always nice to see more Mac users. )

As already indicated, each .java file can contain at most one top-level class that's declared public. (It is not required to contain any.) If a .java file contains a top-level public file, then the name of the file must match that public class name exactly.

But also note that Java is case-sensitive, so "guessgame" (the name of your file) is not the same as "GuessGame" (the name of the class).

The best approach here is to put each top-level class in its own separate file, named to match the class name. This keeps things nice and neat, so you can easily find a class definition by the name of the file. Although as lei suggested, you could get around this by removing the "public" modifier from the class declarations.
