Java: Can't remember class
 

Awhile a go i found class in the API that i found sort of usefull, now in need to find it, but can't remember what it was.

The class idea is really basic (and i know i could just do it myself), but anyway: It's a object that can hold a number and get's automatically reset a certain limit is reached (i remember the limit is passed as second argument to the constructor).

Any ideas on what the class was?

Again, i know i can just do it myself, but i just want to remember what it was.

Thanks...
