Description: The singleton pattern is one of the simplest design patterns. Sometimes we need to have only one instance of our class .In Java, Singleton class is a class that controls the object creation. It means the singleton class allows us to create a single object of the class, at a time. It is usually used to control access to resources, such as database connections or sockets. It ensures that only one connection is made and a thread can access the connection at a time.
