Java – under what circumstances thread Is sleep () the best way to pause a thread?

Thread. Sleep () seems like a very useless concept to me, because the only way I see it work is in the following scenario

public void someFunction()
 {
      //thread does something
      Thread.sleep(50000);
      //Now other threads do something
 }

The problem is, for me, it's just causing trouble I mean, this can be very long. In this case, you may encounter performance problems and may be too long, while other threads may wait for results. In this case, the situation may become very serious

I mean, there are other ways, such as using synchronized and wait, which seems more efficient

So my question is, is there the best choice to use thread sleep?

Solution

Write Java. Java without the sleep () method util. Timer is impossible, or at least it will require you to abuse the wait () method and write a lot of extra code around it to prevent false wakeups
