This code below is for the close() function

   public void close(){

 WindowEvent winClosingEvent = new WindowEvent(this,WindowEvent.WINDOW_CLOSING);
 Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(winClosingEvent);

 }

after that you have to call the function using below code

rs.close();
      pst.close();
       close();
//Employee_info  is the frame name you want to open
        Employee_info s =new Employee_info();
       s.setVisible(true);

Other way of doing that is also

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
