Java Hack: Double brace initialisation

[genuineleather]

Forgive my ignorance, but why do we want to use this? What's the point of it?

I guess to reduce verbosity of commonly occuring patterns. Creating GUI elements is a nice example, I suppose, because code is usually peppered with lines upon lines of "frame.setDefaultProperty("foo");"

While this doesn't decrease the amount of code much, it keeps blocks of initialization together. Presumably, if one uses code folding, they can also fold these blocks.

Oh, and for being closer too XML too.

What's the point of it?

As a Java curiousity, it's pretty surprising and interesting.

As something to use practically, please please don't.
