There is two ways to create threads:
1, implements Runnable
2, class MyThread extends Thread

i can call MyThread.join(); in the example 2 but how can i do that in example 1?

The same way.  A runnable will not stand alone.  It will be given to a thread constructor.  Then you call the methods on the thread.

ex.
MyRunnable myRun = new MyRunnable();

Thread theThread = new Thread(myRun);
theThread.start();

Then it is all the same as you use in #2

If the class which implements Runnable has a Thread member which you're instantiating and over which you're calling the start () method, then expose it through a getter method:

public class Xyz extends Runnable
{
  private Thread t ;
 
  public Something ()
  {
    t = new Thread ( this ) ;
    t.start () ;

  } // end of constructor ()

  public void run ()
  {
    // the run () logic goes here

  } // end of run ()

  public Thread getHandle ()
  {
    return t ;

  } // end of getHandle ()

} // class definition over

Xyz obj = new Xyz () ;
obj.getHandle ().join () ;
