About singleton design pattern

In software engineering, the singleton pattern is a software design pattern that restricts the instantiation of a class to one object. This is useful when exactly one object is needed to coordinate actions across the system.

The concept is sometimes generalized to systems that operate more efficiently when only one object exists, or that Singleton design pattern is one of the GoF (Gang of Four) design patterns, falls under Creational pattern. It ensures at any given point of time only one instance of an object is alive and it does The Singleton pattern ensures that a class has only one instance About singleton design pattern provides a global point of access to that instance.

It is named after the singleton set, which is defined to be a set containing one element. Singleton pattern is one of the simplest design patterns in Java. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object.

This pattern involves a single class which is responsible to create an object while making sure that only Singleton. NET Design Pattern C# and VB. Free source code and UML The singleton pattern is a design pattern that restricts the instantiation of a class to one object.

Lets see various design options for implementing such a class. If you have a good handle on static class variables and access modifiers this should not be a How can the answer be improved? Singleton Design Pattern: Ensure that only one instance of a class is created; Provide a global point of access to the object.
