Java quick array list

List<String> s = Arrays.asList("a1", "str", "mystr");

You can use double brace:

ArrayList<String> s = new ArrayList<String>()
{{
    add("str1");
    add("str hello");
    add("str bye");
    //...
}};

How about:

ArrayList<String> s = new ArrayList<String>();
Collections.addAll(s, "a1", "str", "mystr");

List<String> s = Arrays.asList(new String[] {"a1", "str", "mystr"});
