Using Custom Fonts [java.io.IOException: Error reading font data.]

Question

The title doesn't allow me to say Problem, so the actual error message was -

java.io.IOException: Problem reading font data.
at java.awt.Font.createFont(Unknown Source)
at AddFont.createFont(AddFont.java:11)

at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
at java.awt.EventDispatchThread.run(Unknown Source)

The code is -

     public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
 public void run() {
    try {
        AddFont addFont = new AddFont();
        addFont.createFont();
    } catch (Exception e) {
        e.printStackTrace();
    }
    createGUI();

 } //public void run() Closing
});
}

and the file that I used to get the AddFont addFont-

import java.awt.Font;
import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;


public class AddFont extends MainFrame{
public void createFont(){
Font ttfBase = null;
    Font telegraficoFont = null;{
try {
    InputStream myStream = new BufferedInputStream(new FileInputStream(FONT_PATH_TELEGRAFICO));
    ttfBase = Font.createFont(Font.TRUETYPE_FONT, myStream);
    telegraficoFont = ttfBase.deriveFont(Font.PLAIN, 24);
} catch (Exception ex) {
    ex.printStackTrace();
    System.err.println("Font not loaded.");
}
}
}
}

I was instructed to make a new thread because this is a separate problem from my other one.

Why am I getting this problem, and how can I fix it? I have my TELEGRAFICO.TTF font in my imageFolder, which is really just my resources folder. I use

   public static final String FONT_PATH_TELEGRAFICO = "imageFolder/TELEGRAFICO.TTF";

to call in my path.

What am I doing wrong?

EDIT - I no longer get that error message, and I don't get "Font not loaded". How can I use the font in other class files other than the one I made that method in?

(I want to use that font on buttons in multiple class files. I tried using it here -

regButton = new JButton();
regButton.setText("Foo");
regButton.setAlignmentX(Component.CENTER_ALIGNMENT);
regButton.setFont(telegraficoFont);

But it said telegraficoFont cannot be resolved to a variable. (Because it was in a different class file.)

How can I fix this? Thanks again for the help.

As you have a problem with possible font file locating and font stream creation,

Try this >> Issue loading custom font AND http://forums.devshed.com/showpost.php?p=2268351&postcount=2

To answer your question "how to make this function easy to use everywhere", do as this:

    public class AddFont extends MainFrame {

    private static Font ttfBase = null;
    private static Font telegraficoFont = null;
    private static InputStream myStream = null;
    private static final String FONT_PATH_TELEGRAFICO = "imageFolder/TELEGRAFICO.TTF";

    public Font createFont() {


            try {
                myStream = new BufferedInputStream(
                        new FileInputStream(FONT_PATH_TELEGRAFICO));
                ttfBase = Font.createFont(Font.TRUETYPE_FONT, myStream);
                telegraficoFont = ttfBase.deriveFont(Font.PLAIN, 24);               
            } catch (Exception ex) {
                ex.printStackTrace();
                System.err.println("Font not loaded.");
            }
            return telegraficoFont;
    }
}

And then in your calling class:

    public class Test {

    public static Font font = null;

    public static void main(String[] args) {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                try {
                    if (font == null) {
                        font = AddFont.createFont();
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                }
                createGUI();

            } // public void run() Closing
        });
    }
}
