Static Class: A class that only contains static components and no instance components is referred to as a static class. Singleton Class: It is a class which does not allow you to create multiple instances.
In those cases you can simply wrap the class instance with static members. public static void out(Object msg) { sm_logger.out(msg); } }.

There are three reasons for Singleton, only one of which is that you only want one instance.reate a thread for each singleton at the time that the singleton instance is created. Do not schedule the thread to run, this is not the purpose of the thread. The mere existence of the thread will protect the singleton. Also consider using a registry class which maintains a collection of the singleton instances.
