For example, suppose myInt is an AtomicInteger that initially has the value 5. If two threads both evaluate the expression ++myInt, it is guaranteed that one thread will get the value 6 and the other will get the value 7, and myInt will equal 7 afterward. This would not be true for an ordinary int.
On most processors, this form of thread-safety can be implemented in a lightweight way which is much faster than acquiring a lock. When possible, this class uses these mechanisms to achieve maximum efficiency. On platforms that do not support atomic operations directly it uses locking, which is slower but still guaranteed to produce a correct result.
