For example:
System.out.println("Hello");
This would return Hello world (In the right context) so it actually does return something if I got this right. Or isn't printing actually returning?

Welcome to Treehouse!
If one thinks about what main is doing it might make more sense. A main function is what gets called when we run a program, right? For example, if we were to do java example.java we would be running the main function inside of our example.java file. We can certainly do interactive things like take input from a user or print information out, but the concept of "returning" something to the operating system is a bit nebulous. The only real "return value" that exists is something like a System.exit(int) method that could return an exit status code.
You can take a look at the language specification for more details.
Happy coding,
Ken
