Atomic operation in multi threaded workld

Are atomic operations safe enough to use it in multi threaded app without causing race conditions and other concurrency issue ? Let say that we don't worry about visibility (we read/write everything from CPU).

Yes, java has strictly defined memory model (also known as JSR 133).

There are also out-of-box atomic wrappers for primitive types in java.util.concurrent package, like AtomicInteger.

Atomicity is implemented using compare-and-swap.
