Is there a way to ensure some statements are executed in atomic way

Question

Having some line of statements, is there a simple way to assure it is executed in atomic way?

Answer 1

Atomic? No. Despite what people are saying here, thread-safe doesn't mean atomic:

// this is NOT atomic!
synchronized(this) {
    makeChangeA();
    makeChangeB();
}

if makeChangeB() throws an exception, makeChangeA() will not rollback it's change.

Definition of atomic is "executed either completely, or not at all". Synchronized block is not atomic.

Answer 2

If your emphasis is on "simple way", you can try out the @Synchronized annotation of Project Lombok.
