Sure, all class MUST extends java.lang.Object.



public abstract class Enum<E extends Enum<E>>extends Objectimplements Comparable<E>, SerializableThis is the common base class of all Java language enumeration types.

Enum is new feature in Java Tiger (5.0).

Typesafe Enums
This flexible object-oriented enumerated type facility allows you to create enumerated types with arbitrary methods and fields. It provides all the benefits of the Typesafe Enum pattern ("Effective Java," Item 21) without the verbosity and the error-proneness. Refer to JSR 201.

Yes, enums extend java.lang.Object!
In addition, they have high-quality toString, hashCode and equals methods. They are also Serializable and Comparable.

The Enum API is always a good place to find answers to questions like this.
