Question

What is the difference between these two? A primitive type cannot have “Class”, can it – it is primitive. There are no objects to have a class.

Where does these two make a difference?

Answer 1

I’m not positive what you mean, but — A Class object is a runtime representative of a type. That said, there is such a thing as int.class that is distinct from Integer.class, even though int is not a class. It’s kind of complicated, but it’s necessary to make reflection work even on methods that take primitive arguments or return primitive values, or to distinguish a method that accepts an Integer from a method that accepts an int.

Integer.TYPE, I believe, is equivalent to int.class.
