Hi below is the double checked locking pattern for creating singleton class. Below the code checks whether the "_instance" is null. If null the singleton.class object is locked using the synchronized keyword' Class Singleton{ public static Singleton getInstance() { if (_instance == null) { synchronized(Singleton.class) { if (_instance == null) _instance = new Singleton(); } } return _instance; } } My doubt is that how can we synchronize an object without creating it.Also I could not understand what "Singleton.class" means. is it an object of the current class?    More>>

			

			

			Class Singleton{
			

			

			public static Singleton getInstance() {
			

			if (_instance == null) {
			

			synchronized(Singleton.class) {
			

			if (_instance == null)
			

			_instance = new Singleton();
			

			}
			

			}
			

			return _instance;
			

			}
