Java cannot find symbol error

Question

I know that "cannot find symbol" shows up when there misspelled something or the variable is not in the scope it is used or something like this. But still I cannot figure out what causes that problem in my situation. I have two classes: Driver.java and DisplayPanel.java

Driver.java code :

package csHW9;

import javax.swing.JFrame;
import csHW9.DisplayPanel;

public class Driver {

    public static void main(String[] args){
        JFrame frame = new JFrame("Dungeon Diver");
        DisplayPanel panel = new DisplayPanel();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(panel);
        frame.pack();
        frame.setVisible(true);
    }

}

DisplayPanel.java code:

package csHW9;

import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Point;

import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import javax.swing.*;

import javax.swing.JPanel;
public class DisplayPanel extends JPanel{   
private Dungeon dungeon;

public DisplayPanel(){
    setPreferredSize(new Dimension(600, 600));
    this.dungeon = new Dungeon();
    addKeyListener(new KListener());
    setFocusable(true); 
}

Dungeon is just another class and I'm making its instance in DisplayPanel class.

The error I get is this:

 Driver.java:12: cannot find symbol
symbol  : class DisplayPanel
location: class csHW9.Driver
        DisplayPanel panel = new DisplayPanel();

I don't understand what I'm doing wrong. Any suggestions?

Add `..` to your classpath. Or set CD to `..` and compile `csHW9\Driver.java` rather than just `Driver.java`. — Hot Licks, Nov 12 '12 at 04:50

You need to add import statement in Driver class at top.

Example:

import yourpackage.Driver

I have DisplayPanel imported in Driver – gtboy Nov 12 '12 at 04:26
Your code not reflecting that. Could you update question with exact code? – kosa Nov 12 '12 at 04:27
Please update DisplayPanel code also. – kosa Nov 12 '12 at 04:31
Should I import anything in DisplayPanel? why do i need to update it? – gtboy Nov 12 '12 at 04:33
No. I was asking you to update the question with DisplayPanel class package info. I strongly suspect there might be some typo. – kosa Nov 12 '12 at 04:35
I have both files in the same package. Anyways, I updated DisplayPanel here – gtboy Nov 12 '12 at 04:38
Strange. Are you using any IDE like eclipse? – kosa Nov 12 '12 at 04:42
I do. Eclipse. Can this error be caused by Dungeon object that I instantiate in DisplayPanel? – gtboy Nov 12 '12 at 04:43
