Please provide a method to implement Singleton pattern in Java without the usage of static variables/methods.

The static is part is needed because only one instance is allowed to exist. And with that way you can do that in-memory. Without a static method/variable I would try storing the-only instance in a file and use locking, so noone else can change that. Not good, not performant, maybe not even working ... :)

That's not possible - it wouldn't be the Singleton pattern anymore.
