What is An Singleton Class?

A class whose number of instances that can be instantiated is limited to one is called a singleton class. Thus, at any given time only one instance can exist, no more.

Singleton class is a class which can have only one instantiated object. There is a restriction on the instantiation of the class. Well yes a singleton can be created, but it can't be instantiated by developers, - meaning that the singleton class has control over how it is created.
