标签：get ai System AtomicArray 获取 println out
AtomicInteger ai = new AtomicInteger(1);
//1.获取值
System.out.println("ai.get = "+ai.get());
//2.增加指定值并获取
System.out.println("ai.addAndGet(2) = "+ai.addAndGet(2));
System.out.println("ai.get = "+ai.get());
//3.比较并设置 1.预期值 2.新值 预期值与当前比较 如果相同就设置为新值，返回值，是否设置成功
System.out.println("ai.compareAndSet(ai.get,10) = "+ai.compareAndSet(ai.get(),10));
System.out.println("ai.get"+ai.get());
//获取并递增
System.out.println("ai.getAndIncrement"+ai.getAndIncrement());
System.out.println("ai.get"+ai.get());
//递增并获取
System.out.println("ai.incrementAndGet"+ai.incrementAndGet());
System.out.println("ai.get"+ai.get());
//懒设置（不会保证可见性） volatile保证了可见性
ai.lazySet(8);
//ai.set(8); 感觉跟set没什么区别 会保证可见性
System.out.println("ai.get"+ai.get());
