Unable to recognise ImageViewer...

[RayKnight]

This is the coding I used, I got it directly from a Java book titled
"Introduction to Java Programming - Comprehensive Version 5th Edition"

"import javax.swing.*;
import java.awt.*;

public class Flags extends javax.swing.JApplet
{
public Flags()
{
ImageViewer imageViewer1 = new ImageViewer();
ImageViewer imageViewer2 = new ImageViewer();
ImageViewer imageViewer3 = new ImageViewer();
ImageViewer imageViewer4 = new ImageViewer();
ImageViewer imageViewer5 = new ImageViewer();
ImageViewer imageViewer6 = new ImageViewer();

getContentPane().setLayout(new java.awt.GridLayout(2, 0, 5, 5));
imageViewer1.setImageFilename("/image/us.gif");
getContentPane().add(imageViewer1);
imageViewer2.setImageFilename("/image/ca.gif");
getContentPane().add(imageViewer2);
imageViewer3.setImageFilename("/image/india.gif");
getContentPane().add(imageViewer3);
imageViewer4.setImageFilename("/image/uk.gif");
getContentPane().add(imageViewer4);
imageViewer5.setImageFilename("/image/china.gif");
getContentPane().add(imageViewer5);
imageViewer6.setImageFilename("/image/norway.gif");
getContentPane().add(imageViewer6);
}
}"

It does not allow me to compile and keeps saying they 'cannot find
symbol'

What is wrong?

Where is this ImageViewer class? It's not part of the core API.
Perhaps it is another code sample from the book? Is there a CD with the
book that might contain the class?

At the moment, I'm siding with the compiler. I also have no clue what
you mean by ImageViewer.

Yeah, I've done a file that compiled perfectly with the ImageViewer thing
which I assume is supposed to be part of the file I listed above.

But it doesn't seem to work.

Unfortunately, I have no idea what you just said. I doubt anyone else
does either. The question is the same: where is ImageViewer?

Try posting your exact error message since none of us has a clue as to which
line of code is being identified as being in error.

 

[RayKnight]

Flags.java.13: cannot find symbol
symbol: class ImageViewer
location: class Flags
ImageViewer imageviewer1 = new ImageViewer();

With two ^ point at the first and last ImageViewer.

Am I supposed to use the "package" command or something?

I already made an ImageViewer.class file. It compiled properly and I'm
supposed to make use of that file to display images on this (Flags.java)
file.

You might want to include some of the original message when replying. I just
*think* this might have been a response to a post of mine.

Anyway, based upon the error you quote above, it would appear that
ImageViewer is not found in your class path, or you have not imported it
correctly.
