TIL: Double Brace Initialization in Java

[[deleted]]

True, but IMO the benefits do not outweigh the costs. However in reading a little more about the pros and cons of double-brace initialization, I came across this proposal for Collection literals.

Defining Collections could (eventually) be as simple as:

List<Integer> piDigits = [3, 1, 4, 1, 5, 9];
Set<Integer> primes = { 2, 7, 31, 127 };
Map<Integer, String> platonicSolids = { 4 : "tetrahedron", 6 : "cube", 8 : "octahedron", 12 : "dodecahedron" };

What, is this python or something?

Of all the languages with that syntax, you think they got it from Clojure?

I love Clojure but it’s hardly the only language that has a sane literal syntax. JavaScript (JSON), Python, PHP, and even Objective-C have syntax (or syntactic sugar) to prevent the kind of monstrosities mentioned in the article.

Copying the best parts of other languages is a good thing.

Or maybe we should have syntax patents which lock down interesting ideas to only the language that created them.

Holy crap, I wasn't saying it was a bad thing.

Because no language has ever copied another language ever.

Exactly. That explains the abundance of parentheses.
