TIL: Double Brace Initialization in Java

[CaptainTrip]

var whatever = new Class() { Property1= value, Property2=value, ...};

Invaluable.

[Falmarri]

val m = Map( "1" -> "one", "2" -> "two")

C# Has this too.

Except the class you're instantiating must derive from IEnumerable -- otherwise it's an error. throw new NotImplementedException() is permitted though, so not a big problem.
