图17-2 ：https://bugstack.cn/assets/images/2020/interview/interview-17-2.png 1、nonfairTryAcquire根据源码应该是一个逻辑分支 final boolean nonfairTryAcquire(int acquires) 返回true和false两种情况，应该是一一个“菱形”选择分支。 2、nonfairTryAcquire其中有个子流程 （如果state=0 则cas修改 设置独占线程并返回true，如果state!=0 则判断是否当前线程重入？ 是的话State+1 返回true，其他情况均为false） 3、cas修改共享变量是否成功 并不是 进入current == getExclusiveOwnerThread() 的判断条件，且修改成功后 说明获得了锁 与流程图中不符。
