Unable to compile...

[DrakalDragon]

New here, but I thought this would be the right place to ask. Whenever I try to compile a .class using ColorPanel, I keep getting an error saying it can't find the symbol. Here's the source.

import javax.swing.*;
import java.awt.*;
public class GUIWindow{
	public static void main(String [] args) {
		JFrame theGUI = new JFrame();
		theGUI.setTitle("GUI Program");
		theGUI.setSize(300, 200);
		theGUI.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		ColorPanel panel = new ColorPanel(Color.gray);
		Container pane = theGUI.getContentPane();
		pane.add(panel);
		theGUI.setVisible(true);
	}
}

And I get these errors.

GUIWindow.java:10: cannot find symbol
symbol  : class ColorPanel
location: class GUIWindow
		ColorPanel panel = new ColorPanel(Color.gray);
		^
GUIWindow.java:10: cannot find symbol
symbol  : class ColorPanel
location: class GUIWindow
		ColorPanel panel = new ColorPanel(Color.gray);
		                       ^
2 errors

Any help would be appreciated as I would like not to skip things in this book.

Is ColorPanel a class that you have made yourself or downloaded? It's not a general Java-class, in any case.

The book I got didn't specify to download one, and nowhere did I make one, so I guess I'll have to skip it or work around it. Thanks for your input.

It's probably just a JPanel with a colored background. Try this:

public class ColorPanel extends JPanel {
    ColorPanel(Color color) {
        setBackground(color);
    }
}
