How to finish several modal dialogs by "OK"-labeled Buttons ?

Question

Hello community !
In my Applet I use some modal dialogs . Each of them should be finished by pressing the "OK"-labeled Button . In my ActionListener class there would be statements like that:
if(labeltest.equals("OK"))
dialog1.dispose();
if(labeltest.equals("OK"))
dialog2.dispose();
if(labeltest.equals("OK"))
dialog3.dispose();
But how to distinguish them ? Is this possible or not ?

Your description of JOptionPane.ShowXxxDialog-Methods is interesting . I haven't known before . My question was how to finish ...I think , I did show it to abstract , why I want to solve the problem this way , but it works . Here are the code sequences for those 3 "OK"-Buttons:
     Button okbutton = new Button();
     Button ok2button = new Button();
     Button ok3button = new Button();
// --------------- create Info-Window (Dialog) -------------------------
// *use okbutton*
     dialog.setSize(600,600);
     dialog.addWindowListener(
            new WindowAdapter()
               public void windowClosing(WindowEvent e)
                dialog.setVisible(false);
     dialog.setVisible(false);
     JPanel p = new JPanel();
     p.setLayout(new BoxLayout(p,BoxLayout.Y_AXIS));
     Label lprodukt = new Label("Product :  ...");
     Label lversion = new Label("Version : ...");
     Label lautor = new Label("Author     :  ...");
     Label llabor = new Label("Department: ...");
     Label lcopyright = new Label("Copyright (c) ...");
     lprodukt.setFont(new Font(Font.SANS_SERIF, Font.PLAIN, 18));
     lversion.setFont(new Font(Font.SANS_SERIF, Font.PLAIN, 18));
     lautor.setFont(new Font(Font.SANS_SERIF, Font.PLAIN, 18));
     llabor.setFont(new Font(Font.SANS_SERIF, Font.PLAIN, 18));
     lcopyright.setFont(new Font(Font.SANS_SERIF, Font.PLAIN, 18));
//     Button okbutton = new Button();
     okbutton.setFont(new Font("Arial", Font.PLAIN, 20));
     okbutton.setLabel("OK");
     okbutton.addActionListener(new CMeinActionLauscher());
     p.add(lprodukt);
     p.add(lversion);
     p.add(lautor);
     p.add(llabor);
     p.add(lcopyright);
     Panel panel2 = new Panel();
     panel2.setLayout(new FlowLayout());
     panel2.add(okbutton);
     dialog.setLayout(new BorderLayout());
     dialog.add(p,BorderLayout.CENTER);
     dialog.add(panel2,BorderLayout.SOUTH);
     dialog.pack();
     // -------------------- Info-Window End ---------------------------------
// --------------- create Error-Window1 (Dialog) -------------------------
// *use ok2button*
     derror.setSize(400,600);
     derror.addWindowListener(
            new WindowAdapter()
               public void windowClosing(WindowEvent e)
                derror.setVisible(false);
     derror.setVisible(false);
     JPanel ep = new JPanel();
     ep.setLayout(new BoxLayout(ep,BoxLayout.Y_AXIS));
     Label text1 = new Label("       Filetyp has to be  \".ATT\"  !!!");
     text1.setFont(new Font(Font.SANS_SERIF, Font.PLAIN, 18));
//     Button ok2button = new Button();
     ok2button.setFont(new Font("Arial", Font.PLAIN, 20));
     ok2button.setLabel("OK");
     ok2button.addActionListener(new CMeinActionLauscher());
     ep.add(text1);
     Panel epanel2 = new Panel();
     epanel2.setLayout(new FlowLayout());
     epanel2.add(ok2button);
     derror.setLayout(new BorderLayout());
     derror.add(ep,BorderLayout.CENTER);
     derror.add(epanel2,BorderLayout.SOUTH);
     derror.pack();
     // -------------------- Error-Window1 End --------------------------------
  // --------------- create Error-Window2 (Dialog) -------------------------
// *use ok3button*
   doperr.setSize(400,600);
     doperr.addWindowListener(
            new WindowAdapter()
               public void windowClosing(WindowEvent e)
                doperr.setVisible(false);
     doperr.setVisible(false);
     JPanel op = new JPanel();
     op.setLayout(new BoxLayout(op,BoxLayout.Y_AXIS));
     JLabel optext1 = new JLabel("Operanderror occured !!!");
     optext1.setFont(new Font(Font.SANS_SERIF, Font.PLAIN, 18));
     System.out.println("operror: "+operror.getText());
     operror.setFont(new Font(Font.SANS_SERIF, Font.PLAIN, 18));
     JLabel optext2 = new JLabel("Korrektur vom Entwickler anfordern !!!");
     optext2.setFont(new Font(Font.SANS_SERIF, Font.PLAIN, 18));
//     Button ok3button = new Button();
     ok3button.setFont(new Font("Arial", Font.PLAIN, 20));
     ok3button.setLabel("OK");
     ok3button.addActionListener(new CMeinActionLauscher());
     op.add(optext1);
     op.add(operror);
     op.add(optext2);
     Panel opanel2 = new Panel();
     opanel2.setLayout(new FlowLayout());
     opanel2.add(ok3button);
     doperr.setLayout(new BorderLayout());
     doperr.add(op,BorderLayout.CENTER);
     doperr.add(opanel2,BorderLayout.SOUTH);
     doperr.pack();
  // -------------------- Error-Window2 End --------------------------------
  class CMeinActionLauscher implements ActionListener
    public void actionPerformed(ActionEvent e)
      String label;
      boolean result = false;
      Object source = e.getSource();
      label = e.getActionCommand();
      System.out.println("label: "+label);
      if(label.equals("Programm beenden"))
         System.exit(0);
      if(label.equals("Öffnen"))
         DateiLaden();
      if(label.equals("Info"))
          dialog.setBounds(450,400,400,260);
          dialog.setVisible(true);
          dialog.pack();
      if(label.equals("Beschreibung Software-Id-Verwaltung"))
//          doku.setBounds(550,350,950,600);
          doku.setBounds(400,350,950,600);
          try
              System.out.println("url: "+url);
              JEditorPane htmlPane = new JEditorPane( url );
              htmlPane.setEditable( false );
              htmlPane.setContentType("text/html");
              htmlPane.putClientProperty(JEditorPane.W3C_LENGTH_UNITS, Boolean.TRUE);
              htmlPane.setFont(new Font(Font.SANS_SERIF, Font.PLAIN, 18));
              htmlPane.validate();
              htmlPane.repaint();
              doku.add( new JScrollPane(htmlPane) );
              System.out.println("url: "+url);
          } catch( IOException eio )
                System.err.println( "Error displaying " + url );
          doku.setVisible(true);
//          doku.pack();
      if(label.equals("SYSCON-Kdo erzeugen"))
         KdoErzeugen();
        if (source == ok2button)
            derror.setVisible(false);
            derror.dispose();
        if (source == ok3button)
            doperr.setVisible(false);
            doperr.dispose();
        if (source == okbutton)
            dialog.setVisible(false);
            dialog.dispose();
  }For the ok2button I could use JOptionPane.showMessageDialog but how to do it for th otherones ?
