int[] versus Integer or IntHolder

It's a simple ( and old ) trick. Instead of storing Integers or IntHolder objects in tables or doing weird things to return multiple primitive values - just use an int[1].

I don't know if such trivia is apropriate for a weblog, everyone probably knows it - but I've seen - and even written - code doing increment on Integers in a map ( which involves a lot of garbage and pretty ugly code ).
