    Default Waiting for another thread to finish

    I have a method with two threads (1 &2) which run at the same time. The current thread must stop right after the ‘thread2.start()’ statement until thread2 & thread1 are finished. There appears to be multiple approaches to do this but I find them confusing. Can anybody point to me a simple approach to accomplish this? Join does not appear to work since thread 1 & 2 must run at the same time. Thanks in advance

    Runnable storm = new Storm();
    Runnable UpdatePB = new UpdatePB();

    //these two threads must run at the same time
    thread1 = new Thread(storm);
    thread2 = new Thread(UpdatePB);


    //code must stop here until thread2 is finished

    Why do you say join doesn't work? What have you actually tried?

    try {
    catch(InterruptedException e) {
    System.out.println("Exception caught : " + e);

    It works.
