In this video we have explained Singleton Class and its real time uses. This is one of the most asked topics in Java interviews. The singleton pattern is implemented by creating a class with a method that creates a new instance of the class if one does not exist. If an instance already exists, it simply returns a reference to that object. To make sure that the object cannot be instantiated any other way, the constructor is made private.
