Java ArrayList and HashMap on-the-fly

Question

Can someone please provide an example of creating a Java ArrayList and HashMap on the fly? So instead of doing an add() or put()

Answer 1

A nice way of doing this is using Google Collections:

List list = ImmutableList.of("A", "B", "C");

Map map = ImmutableMap.of(
  1, "A",
  2, "B",
  3, "C");
