Singleton Thread safe class

[userj2ee]

Hi,

Can anyone tell me how to make a Singleton thread safe class without the use of Synchronized method or block? This is one question which is asked in all the interviews i face.

Thanks for the help

A class is loaded amd initialized in a thread safe way, so this'll do:

public class Singleton {
   private static Singleton instance= new Singleton();
   public Singleton getInstance() { return instance; }
   ...
}

kind regards,
