Is there possible to awake a thread that being sleep??

Based on some logic, sometimes i would like to awake the MyThreadName at specific time secs.

From inside of it or outside?

You could always just interrupt it.

class MyTread extends Thread
public void run()
{
 try{
    sleep(30000);
 }
 catch(InterruptedException ie)
 {
    System.out.println("Fine, I'll get up :| ")
 }
} 
 

....
 
public static void main(String args[])
{
  Thread t = new MyThread();
  t.start();
  t.interrupt();
 
}

From your mention of logic to decide when to wake it up I wondered if you might know the wakeup time before you go to sleep? If so,it's pretty easy to do something like this:

private void sleepUntil(Date wakeTime)
{
   sleep(wakeTime.getTime()-System.currentTimeInMillis());
}

Or see Timer to make something happen at a specific time.

If you don't know the wake time before you sleep, that interrupt suggestion is perfect.
