线程等待两种方法的唤醒的效率比较

public class CallResult {
    private volatile boolean  noFinish = true;

    public boolean isNoFinish() {
        return commandIsFinish;
    }

    public void setNoFinish(boolean noFinish) {
        this.noFinish= noFinish;
    }

}

CallResult  callResult = new CallResult();
// .... 把callResult放到队列，让队列另一端的线程去处理

/* 1. 无锁等待方式，等待队列另一端的线程把isNoFinish设值为false */
while(callResult.isNoFinish) { 
    Thread.yield();
}

/* 2. 锁等待方式， 等待队列另一端的线程notify().  测试结果这种方式性能更高*/
synchronized (callResult) {
    try {
             callResult.wait();
     } catch (InterruptedException e) {
            e.printStackTrace();
     }
}
