void and return

For starters I still don't undersatnd basically everything so sorry for being stupid Do you always have to use return in non void methods since its the only way to get a value out of it? Why would I make non void method without a return?

Yes, you always have to use the return statement in a non-void method. (there's one minor exception to this, although that's not worth mentioning here)

if the return type is not void, youre guaranteeing to the caller that the method will return something so you have to return
