Java - thread.sleep 的替代品

我需要将 while 循环暂停特定的毫秒数。我尝试过使用 Thread.sleep(duration) 但它不准确，特别是在循环场景中。毫秒精度在我的程序中很重要。

这是我不想返回检查条件直到expectedElapsedTime已经过去了。

while (condition) {
    time = System.currentTimeMillis();
    //do something
    if (elapsedTime(time) < expectedElapsedTime) ) {
        pause the loop  // NEED SUBSTITUTE FOR Thread.sleep()
    }
    // Alternative that I have tried but not giving good results is 
    while ((elapsedTime(time) < expectedElapsedTime)) {
        //do nothing
    }
}

long elapsedTime(long time) {
   long diff = System.currentTimeMillis() - time;
   return diff;
}

Try a 调度线程池执行器 http://docs.oracle.com/javase/6/docs/api/java/util/concurrent/ScheduledThreadPoolExecutor.html。它应该提供更可靠的计时结果。
