String[] allFontNames = GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames();

From the JavaDocs for getFont():

=================

Returns a Font object from the system properties list. nm is treated as the name of a system property to be obtained. The String value of this property is then interpreted as a Font object according to the specification of Font.decode(String) If the specified property is not found, or the executing code does not have permission to read the property, null is returned instead.

====================

The default system properties do not contain any font information. You can use the decode() method directly, or use the getFont() method that accepts a Map of attributes.Here's an example:

====================

import java.awt.*;

import java.awt.event.*;

import java.awt.font.*;

import javax.swing.*;

import java.util.*;

public class FontExample {

private final String[] allFontNames = GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames();

private final Map fontAttributes = new HashMap();

private JLabel fontLabel;

private int currentIndex = -1;

FontExample() {

fontAttributes.put(TextAttribute.SIZE, 36);

fontAttributes.put(TextAttribute.POSTURE, TextAttribute.POSTURE_REGULAR);

JFrame f = new JFrame();

f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

JButton nextButton = new JButton("NextFont");

fontLabel = new JLabel("", JLabel.CENTER);

nextFont();

nextButton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent ae) {

nextFont();

}

});

f.add(fontLabel,BorderLayout.CENTER);

f.add(nextButton,BorderLayout.SOUTH);

f.setSize(400,300);

f.setVisible(true);

}

public static void main (String[] args) {

new FontExample();

}

private void nextFont() {

currentIndex++;

if (currentIndex >= allFontNames.length) {

currentIndex = 0;

}

fontAttributes.put(TextAttribute.FAMILY, allFontNames[currentIndex]);

//Get font using attributes

Font nextFont = Font.getFont(fontAttributes);

//Or, get the font by calling decode() directly

//Font nextFont = Font.decode(allFontNames[currentIndex]+"-PLAIN-36");

fontLabel.setFont(nextFont);

fontLabel.setText(nextFont.getFontName());

}

}

Thanks again for FontExample. I changed the JLabel to JTextArea and formed a string of printable characters with 3 newlines and got a nice view of the Fonts. Too bad one has to form the big array of names. Is there a way to get just the one or very few Fonts I want for a program without this? It seems that graphics.getFont(String) should have done it but doesn't work.
