MutableInteger

java.lang.Object

public class MutableInteger extends Object

A MutableInteger is like an Integer but mutable, to avoid the excess object creation involved in c = new Integer(c.getInt()+1) which can get expensive if done a lot. Not subclassed from Integer, since Integer is final (for performance :-))
