Using an inner class named 1?HelloWorldSwing$1

There could be something wrong in your java source code.

Please post your code.

Hi ,Thanks alot for your response . Here is the source code.

import javax.swing.*;

import javax.swing.JApplet;

import javax.swing.SwingUtilities;

public class HelloWorldSwing extends JApplet {

/**

 * Create the GUI and show it.  For thread safety,

 * this method should be invoked from the

 * event-dispatching thread.

 */

private void createAndShowGUI() {

    //Create and set up the window.

    JFrame frame = new JFrame("HelloWorldSwing");

    

    //Add the ubiquitous "Hello World" label.

    JLabel label = new JLabel("Hello World");

    frame.getContentPane().add(label);



    //Display the window.

    frame.pack();

    frame.setVisible(true);

}

public void init() {

    //Execute a job on the event-dispatching thread:

    //creating this applet's GUI.

    try {

        SwingUtilities.invokeAndWait(new Runnable() {

            public void run() {

                createAndShowGUI();

            }

        });

    } catch (Exception e) {

        System.err.println("createGUI didn't successfully complete");

    }

}

}

Your code works as is when I try it. Make sure you’ve compiled it with JDK 1.4.2 and included all *.class files.
