Answer 1

A class literal is an expression consisting of the name of a class, interface, array, or primitive type, or the pseudo-type void, followed by a `.' and the token class.

1. An enum is a kind of class and an annotation is a kind of interface.
2. Every array also belongs to a class that is reflected as a Class object that is shared by 3. all arrays with the same element type and number of dimensions.
3. The primitive Java types (boolean, byte, char, short, int, long, float, and double), and
4. The keyword void are also

represented as Class objects.

So System.out.println(int.class); will print int whereas System.out.println(Integer.class); will print class java.lang.Integer.
