Title
Body
Consider I have a Singleton class defined as follows. public class MySingleton implements Serializable{ private static MySingleton myInstance; private MySingleton(){ } static{ myInstance =new MySingleton(); } public static MySingleton getInstance(){ return MySingleton.myInstance; } } The above definition according to me satisfies the requirements of a Singleton.The only additional behaviour added is that the class implements serializable interface. If another class X get the instance of the single and writes it to a file and at a later point deserializes it to obtain another instance we would have two instances which is against the Singleton principle. How can I avoid this or am I wrong in above definition itself.
