Here I would like to demonstrate a simple use of JMenuItems being used with Single Listener for the entire system. A simple sample of use would probably be SingleInstance Desktop Application. Lets see how that is done here. First lets create a OneListener class that should be able to listen to ActionEvents and also be able to add Commands to itself. Please refer to my previous post on Command,Singleton if you would like to see more about this patterns and there usage.

Factories have been a key pattern in building applications, its fascinatingly simple, effective and to the point. When starting to learn a design oriented approach to applications or API, I would always recommend a factory pattern as one of the key starting notes of highlight in your design. So today I am talking about the Abstract Factory pattern. Its not an “abstract” class or object that you call a pattern. But its a Factory of facotries and that is what exactly makes it so much wordingly abstract.

This being my first existence on the network and I just want to make sure that I would come back to this blog page again sometime and keep on writing. For now this is a quick 5 min walk through of getting your hands dirty on the Singleton Pattern. As any ones first pattern Singleton always seems to be the easiest to adapt and ironically always the mistress of your pains; when you realize the act wasn’t right in the first place.
