Effective Java Item #77 - Serialization of singleton objects - Why should I have to use readResolve?

Question

Effective Java #77 states that we have to use readResolve to preserve the Singleton guarentee during serialization. They have used the example.

Answer 1

I'd suggest creating a proxy class inside your singleton class to hold all of your variables. Then you can have accessor functions [getProxyClass() & setProxyClass()]. Make the proxy class serializable, then when you go to serialize or deserialize use the proxy class and just use the accessor functions to get or set it. If you do it this way it cuts out a lot of the mess involved with the singleton class.
