The following compiles from a java file to a class file, but when I go
to view it in a browser, i get the following error:

Applet clickHere can't start: error: java.lang.ClassFormatError: class
already loaded

// Below is the clickHere.java code

import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public class clickHere extends Applet implements MouseListener{
 String DisplayStr=new String("Click Here");
   public void init() {
    addMouseListener(this); // tell system to send us mouse events
      System.out.println("Welcome to ClickHere!");
   }
 public void paint(Graphics g) { //graphics object g
    g.setColor(Color.blue);
      g.drawRect(0,0,150,80);
      g.drawString(DisplayStr,50,20);
   }
   public void mouseClicked(MouseEvent evt) {
    showStatus("Welcome"); //shows up at bottom of window
      DisplayStr="Thanks";
      repaint();
   }
 public void mouseEntered(MouseEvent evt) { } //req'd to be overloaded
 public void mouseExited(MouseEvent evt) { }  // Event evt
 public void mousePressed(MouseEvent evt) { }
 public void mouseReleased(MouseEvent evt) { }
}
