It's also possible to achieve thread-safety using the set ofatomic classesthat Java provides, includingAtomicInteger,AtomicLong,AtomicBoolean, andAtomicReference. 使用java提供的原子类也是可以实现线程安全,他们包括XXXX Atomic classes allow us to perform atomic operations, which are thread-safe, without usin...

Atomic classes allow us to perform atomic operations, which are thread-safe, without using synchronization. An atomic operation is exec...
