For review reasons is that important to you and your colleagues. I think most people only see these advantages if nobody uses them: they would be glad to have them. A few tips and backgrounds, too: is is about the obstacles and the possibillities with Javas Double Brace Instatiation: http://bit.ly/endUIi I hope I could help a little.

I just recently came across another example of this kind of initialization. JMock uses this same kind of initializer pattern to create mock objects; its documentation calls it "double brace" notation. Generally, this is a way to create a simple "DSL" (domain specific language) - define a class with a bunch of useful methods, create a new default instance, and then any of the methods can be called within the "double braces" - like the add() method above. It's like defining a little mini-script within Java. At the end of the double braces, the object you just created carries the results of the method calls - in this case, a HashMap has been populated, but any kind of data could be added.

I was looking for a way to put a Map into an enum, and couldn't figure out how to get the map initialized. This code works much better than passing in separate key and value arrays and worrying over whether they've gotten out of sync. http://torrez.us/archives/2008/03/08/560/comment-page-1/#comment-215227 Dor Thu, 30 Oct 2008 08:44:34 +0000 http://torrez.us/archives/2008/03/08/560/#comment-215227 Just what i have looked for. http://torrez.us/archives/2008/03/08/560/comment-page-1/#comment-208264 Axel Mon, 17 Mar 2008 09:13:38 +0000 http://torrez.us/archives/2008/03/08/560/#comment-208264 I don't see how this operation is costly. You may check this with a profiler, but I would be surprised, if the second example would take >1 milisecond longer than the first example on a modern PC. Class loading is clearly not expensive. On the other hand there are hidden costs: It may surprise future maintainers and its not that easy to look up the values of the hashmap in a debugger. Class loading is clearly not expensive.
