public class apltw extends JApplet {

 JFrame f1 = new JFrame("frame1");
    JFrame f2 = new JFrame(" frame2");
    JFrame f3 = new JFrame("frame3");
 JLabel label0 = new JLabel("~~COMMON PROPERTIES ~~");

 public void init() {
defination of Textboxes and Lables , adding them to frames.
}
public static void main(String[] args) {
        run(new apltw(), 1000, 1000);
    }

    public static void run(JApplet applet, int width, int height) {
        apltw.applet = applet;
        apltw.width = width;
        apltw.height = height;
        applet.init();
        applet.start();

    }
some other methods and classes which are called in init() .
}
