AtomicInteger原子操作细节 了解具体的原子操作细节,比如我们参考getAndIncrement方法. Unsafe利用value字段的内存地址偏移,直接完成操作。 public final int getAndIncrement() { return U.getAndAddInt(this, VALUE, 1); } 1. 2. 3. 因为getAndIncrement需要返回数值,所以需要添加失败重试逻辑。 public final int ...
In this tutorial, we’ll explain the difference between the pre-increment and post-increment operators in a loop. 2. Pre-increment and Post-increment Many programming languages such as Java or C offer specialized unary operators for the pre-increment and post-increment operations: () and ()....
