In this Video Watch What is Singleton in Java .
Singleton class in Java contains only one object at one time. For the designing of the singleton class, the construction needs to be private. The static method needs to be written to return the object of the singleton class. In singleton class, methods like getInstance() are used.
When the getInstance method is called for the first time in the singleton class, an object of the class name single_isntance is created and is returned to the variable. A single class is initiated in the main class by 3 objects x,y and z by calling the method getInstance(). Singleton class is also implemented to offer global point access to the object.
