Is there a way to do this in one line?

Question

I feel like this two line program should be expressible in one line but I can't get the {} array literal to work inside the asList call. Is there a way?

String[] a = {"Whiskey", "Tango", "Foxtrot"};
myList.addAll(Arrays.asList(a));

Because I care about writing beautiful code. And in the answer below I learned something very useful! — pitosalas, Mar 05 '16 at 15:56
I don't think this makes it any more readable especially if you have more than a few items, but sure thing enjoy — Idos, Mar 05 '16 at 15:57

Arrays.asList receives an ellipsis (T...), so you just don't need the array literal:

myList.addAll(Arrays.asList("Whiskey", "Tango", "Foxtrot"));

As I don't think you need string array here, you can use like that

List<String> x = new ArrayList<String>() {{add("Whiskey");add("Tango")add("Foxtrot");}};
