如何测量线程等待时间? [英] How can I measure thread waiting time?

问题描述

我找不到如何测量线程等待锁定的时间.我必须确定一个线程是否正在等待锁定超过1秒，如果是，则运行另一个线程.谢谢！

I couldn't find out how to measure the time that a Thread is waiting locked. I have to determine if a Thread is waiting locked more than 1 second and if so to run another Thread instead. Thanks!

推荐答案

尝试一下:

long startTime = System.nanoTime();
methodToTime();
long endTime = System.nanoTime();

long duration = endTime - startTime;
