Why empty java file gets compiled correctly if it is the requirement that filename should match class name which contains main method?

It's required that any public outer class defined in a source file matches the name of the file. That the main method should be in a public class defined in a source file of the same name is nothing to do with whether every source file should have a matching public class defined, or any class defined at all. Though, if the source file doesn't define any classes, then it's not much use really.
