java - Enums, Singletons and Deserialization

Question

Enums are considered best way for singletons and one of reasons for this is that it implicitly inherits Serializable.

But how enums prevents de-serialization problem of singletons?

Answer 1

The serialization mechanism handles them in a special, specific way. But traditional singletons can be deserialized fine by defining a readResolve() method that returns the unique instance. See http://www.oodesign.com/singleton-pattern.html for an example.
