Hi,

Whether ur file got compiled? Are u able to see your class file.
Ur path is correct?

Gothru this article for guidance.
JavaWorld Forums: Exception in thread "main" java.lang.NoClassDef...

Code:

---

import java.awt.*;
import java.applet.*;
import java.io.*;
 public class MenuDemo  {
          public static voidmain(String args[])
        {
                MenuBar mb =new MenuBar();
                Menu f1=new Menu("file");
                f1.add(new MenuItem("new"));
                f1.add(new MenuItem("open"));
                f1.addSeparator();
                f1.add(new MenuItem("save"));
                f1.add(new MenuItem("save as"));
                f1.addSeparator();
                f1.add(new MenuItem("close"));
                mb.add(f1);
                Frame f=new Frame("Menus Demo");
                f.setSize(300,300);
                f.pack();
                f.setVisible(true);
        }
        }

Your void and your main words are concatenated together. Is this a typographical error or is this how your program truly looks? In other words, this:

Code:

---

public static voidmain(String args[])

---

should look like this:

Code:

---

public static void main(String args[]) // note gap between void and main

---

Also, you really should be learning Swing, not AWT.
