Singleton Pattern: Structure static getInstance() : Singleton private Singleton() static my_instance : Singleton Singleton Singleton involves only a single class (not typically called Singleton) That class is a full-?edged class with other attributes and methods (not shown) The class has a static variable that points at a single instance of
What is Singleton? - Definition from Techopedia
Recall the second weakness of Java constructors Java constructors always return a new object never a pre-existing object • Singleton : only one object exists at runtime –Factory method returns the same object every time • Interning : only one object with a particular (abstract) value exists at runtime

Singleton Pattern with Single-Threaded EnvironmentFor single-threaded applications we will have to do:Create a private static instance of the Singleton class Keep the constructor private Create a private static getInstance() method to return the same object always public class Singleton { /* private instance variable */ private static
Thinking in Patterns with Java
In this example making the class final prevents cloning Since Singleton is inherited directly from Object the clone( ) method remains protected so it cannot be used (doing so produces a compile-time error) However if you’re inheriting from a class hierarchy that has already overridden clone( ) as

- The singleton pattern is used in programming languages such as Java and .NET to define a global variable. A single object used across systems remains constant and needs to be defined only once rather than many times. A singleton is intended to provide only one instance of itself while facilitating a global point of access.
