Hidden Features of Java

My preferred initialization for lists of strings (shorter than the anon class + instance init e.g.)

  List<String> fruits = Arrays.asList("apple,orange,pear".split(","));

Why not

  Arrays.asList("apple", "orange", "pear")

I personally prefer Guava's immutable collections:

    List<String> fruits = ImmutableList.of("apple", "orange", "pear");

It also works for sets and maps:

    Set<String> fruits = ImmutableSet.of("apple", "orange", "pear");
    Map<String, Integer> fruitCounts = ImmutableMap.of("apple", 3, "orange", 2, "pear", 6);

You save "" for each extra item, which gets annoying on longer lists.
