in python:

    >>> from collections import defaultdict
    >>> map = defaultdict(int)
    >>> for word in ['hi', 'there', 'hi']:
    ...   map[word] += 1

I am glad Java has this stuff now, but it's a little surprising that its tools are still so obtuse relative to competitors.

edit: I should have foreseen the derailment caused by and nitpicking to follow a comment like this. Sorry folks!
