Idea to Java ArrayLists

[kedar mhaswade]

Philipp,

Wouldn't Arrays.asList
<http://docs.oracle.com/javase/8/docs/api/java/util/Arrays.html#asList-T...->
work for you?

e.g.
List<String> strings = Arrays.asList("1", "2", "3"); or
List<String> strings = Arrays.asList("1", "2", "3", "4", "five");

Regards,
Kedar
