Make all other works stop until a thread finishes execution

Question

Hi,
I have the following thread.
_thread = new Thread()
               public void run()
                    try
                         //Something is executing here
                    catch (Exception e)
                              System.out.println(e);
          _thread.start();Once the control gets inside this thread, all other works should be posed and the other works should be resumed only once this thread finishes execution.
how can i do that?
Please help.
Any help in this regard will be appreciated with dukes.
Regards,
Rony

Normally you would only do that for controlling access a specific object or resource, so only one thread can access the object or resource at a time.
The basic threading operations are suited to such uses, rather than managing the order a sequence of processes.
You could also use join, but that requires that all the threads threads you want to pause have a reference to the thread you're creating, and need a mechanism to change their behaviour when the thread is started, rather than having to the object used for synchronisation passed to them when they are started. However, with synchronization you can't guarantee which thread gets the lock on the object in which order, so you may want to do it using join.
The more important question is why you want the other threads to pause.
