Singleton Design Pattern in OOPS

The singleton class declares the static method getinstance() that returns the same instance of its own class. Formally the singleton pattern is defined as ensuring that only a single instance of a class exists and a global point of access to it exists. Controlled access to a single object is necessary.

Singleton Pattern Uml Diagram - Web , the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance. The class implementing the singleton pattern simply defines a private constructor, making sure that no other class can construct it. In this diagram the only public interface element is the static getsingleton method. The class constructor is private, and you can only access the instance through an accessor method, which could be getinstance. What is singleton design pattern?

Web it is explained later, but an implication of the pattern is that there is only one instance of a class instantiated—never two. Instead, it stores a static reference to a single instance of itself, and includes a get method to access that single instance.
