Thoughts on Singleton Design Pattern – Good Bad Ugly
-- Sponsored Ads --
Singleton patternis one of the best-known patterns in software engineering. Essentially, a singleton is a class which only allows a single instance of itself to be created, and usually gives simple access to that instance. Most commonly, singletons don’t allow any parameters to be specified when creating the instance – as otherwise a second request for an instance but with a different parameter could be problematic. (if the same instance should be accessed for all requests with the same parameter, the factory pattern is more appropriate. )

- Double-checked locking and the Singleton pattern – All programming languages have their share of idioms. Many are useful to know and use, and programmers spend valuable time creating, learning, and implementing them. The problem is that some idioms are later proven not to be all that they were purported, or to simply not work as described. Double-checked locking is one such idiom in the Java programming language that should never be used. In this article, Peter Haggar examines the roots of the double-checked locking idiom, why it was developed, and why it doesn’t work.

Singleton pattern is: make all the methods as static, if for any reason you cannot make all the methods as static, then go for static instance approach. I feel keeping all methods as static methods is better design and developer friendly.
