Join blocks the current thread until the thread you issued the join on dies.
The yield() method causes the current thread to move from the running state to the runnable state, so that other threads may get a chance to run. However, the next thread chosen for running might not be a different thread:

  public static void yield()

When a thread calls join() on another thread, the currently running thread will wait until the thread it joins with has completed:

  void join()        
  void join(long millis)
  void join(long millis, int nanos)
