Is there any efficient way to keep a thread, which has ActionListener in it's run method, alive until a click event has occured?

Question

      boolean flag = true;
      public void run(){
      // some code
         loginButton.addActionListener(new ActionListener() { 
         public void actionPerformed(ActionEvent e) {
             flag = false; 
             // Some code
         }
      }); 

      while(flag){}
      }

I am using while loop till the actionListener is invoked which I think is silly perhaps. Please let me know if this can be done in more efficient way.

actionPerformed will be called from UIThread. There is no need to keep your thread alive — ControlAltDel, Apr 20 '16 at 13:14

You dont need a Thread for the Listener itself, the Java UI Thread calls your Listener for you.

However if you want your response to the event non-blocking do the following:

// no need for a second thread here
loginButton.addActionListener(new ActionListener() { 
     public void actionPerformed(ActionEvent e) {
         // If you dont want to block the UI Thread make a new Thread here
         new Thread(YOUR_RUNNABLE).start();
     }
}
