Question

Enum is in the java.lang.Enum, and Object is in the java.lang.Object. So, why is Enum not an Object? (I am getting a java.lang.ClassCastException)

I want to make a class that can accept both Object and Enum, like this…

public class MyType<T extends Enum<T>, Object> {

But this gives a compilation error. How can i make my MyType so that it can accept all (or both) type of classes? (Enum or Object)?

Answer 1

An Enum is an Object. See http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Enum.html
So

MyType<Object> {

should work.
