//Very simple, pay attention to the position of the picture

this.setIconImage(Toolkit.getDefaultToolkit().getImage(this.getClass().
                getResource("images/myicon.gif")
                          ));

It doesn’t need to be so complicated, right?
If it is JFrame, call frame.setIconImage(new ImageIcon(url).getImage());//url is the image path
If it is JDialog directly dialog.setTitle("");
