I am into java from last one month ank keep on exploring it in the want to
recently i created a application cum applet in the same class like
applet is doing its own task and there is a main method in the code
that does entirly different task lets assume displaying *'s on the dos prompt the program is getting complied and belive it its running as desired
but the only problem that i m facing if i use appletviewer Myclass.java
only the appletprog is displayed
and if i run java Myclass than only dos task is done

it tryied different ways to do it but was not succesful
please do not get irreated if its bizzered but if you really have a solution for it .i will appreciate it
thanking you

Yes you can run an Applet from an application. The magic bit is providing an AppletContext and AppletStub!
Here's how you start it:
        wpa = new WayPointsApplet(this);
        new AppletWrapper(wpa, 380, 320);Here's the class definition: (includes code for my application that can be ignored.
// Define a wrapper class for the applet
class AppletWrapper extends Frame implements AppletStub, AppletContext {
    Applet applet;
    // Constructor
    AppletWrapper(Applet a, int x, int y) { 
          applet = a; 
          setTitle(a.getClass().getName());
          setSize(x, y);
          Dimension ss = Toolkit.getDefaultToolkit().getScreenSize();
          setLocation((ss.width-x)/2, (ss.height-y)/2);
          add(a, "Center");
          a.setStub(this);
          // Trap window closing
          addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent we) {
                // Test if Write left undone before exiting???
                if(WayPoints.wpa != null) {
                  if(!WayPoints.wpa.okToExit())
                     return;           // Ignore
                applet.stop();
                applet.destroy();
                if(WayPoints.debug || WayPointDefs.plot_debug) {
                  SaveStdOutput.stop();
                System.exit(0);         // EXIT Program
          });  // end WindowListener
          a.init();
          show();
          a.start();
   } // end constructor
    // AppletStub methods
    public boolean   isActive() { return true; }
    public URL       getDocumentBase() { return null; }
    public URL       getCodeBase() {
        return WayPoints.currDir;
    public String    getParameter(String name) {
        if (name.equalsIgnoreCase("DEBUG")) {
            if (WayPoints.debug)
                return "YES";
            else
                return "NO";
        if(name.equals("PLOTDEBUG"))
            return (WayPointDefs.plot_debug ? "YES" : "NO");
        if (name.equalsIgnoreCase("SERVER"))
            return "NO";
        return "";
    public AppletContext getAppletContext() { return this; }
    public void      appletResize(int width, int height) {}
    // AppletContext methods
    public AudioClip getAudioClip(URL url) { return null; }
    public Image     getImage(URL url) { return null; }
    public Applet    getApplet(String name) { return null; }
    public Enumeration getApplets() { return null; }
    public void      showDocument(URL url) {}
    public void      showDocument(URL url, String target) {}
    public void      showStatus(String status) {}
} // end class AppletWrapper
