Does Java have mutable types for Integer, Float, Double, Long?

Question

I am in a situation where I want to use mutable versions of things like Integer. Do I have to use these classes (below) or does Java have something built in?

Answer 1

Since JDK 1.5 java now has java.util.concurrent.atomic.AtomicInteger

This is a thread safe mutable integer, example of use:

final AtomicInteger value = new AtomicInteger(0);

then later on:

value.incrementAndGet();
