Java – Most Efficient Way to Increment a Map Value

I hope this question is not considered too basic for this forum, but we'll see. I'm wondering how to refactor some code for better performance that is getting run a bunch of times.

Say I'm creating a word frequency list, using a Map (probably a HashMap), where each key is a String with the word that's being counted and the value is an Integer that's incremented each time a token of the word is found.

In Perl, incrementing such a value would be trivially easy:

$map{$word}++;

But in Java, it's much more complicated. Here the way I'm currently doing it:

int count = map.containsKey(word) ? map.get(word) : 0;
map.put(word, count + 1);

Which of course relies on the autoboxing feature in the newer Java versions. I wonder if you can suggest a more efficient way of incrementing such a value. Are there even good performance reasons for eschewing the Collections framework and using a something else instead?

Update: I've done a test of several of the answers. See below.
