Because you cannot have a main that isn’t part of a class. Hence a class must exist in order to have a valid program.
But that’s really nit-picking since you don’t actually have to instantiate that class to do something. You can write a complete program with just static methods that instantiate no objects at all.
Whether it’s a useful program without using objects like
System.outis another matter.Some OO purists will argue that Java isn’t pure OO and they’re probably right (in my opinion). That doesn’t make it any less useful.
