swing - ActionListener not working Java -

what missing here?

 public class abc extends jframe    {  private jbutton save = new jbutton("save");   public abc() {     jpanel p = new jpanel();     save.addactionlistener(new savel());     p.add(save);     container cp = getcontentpane();     p = new jpanel();     p.setlayout(new gridlayout(2, 1));      cp.add(p, borderlayout.north);   }    }   class savel implements actionlistener {          public void actionperformed(actionevent e) {                 system.out.println("hello"); // nothing happens          } }

why doesn't actionlistener work here

you creating jpanel, adding jbutton it, creating new jpanel , adding panel jframe. need adding original panel content pane.
