Getting JTextArea to display fixed-width font without antialiasing

Question

Does anybody know how to get JTextArea to display a fixed size font on all platforms?

I want to make a simple code editor with save/open functionality, which is simp

You can use the logical font "monospaced". While it guarantees to have a font that has the same size for all characters, it won't be the same on all platform.

import java.awt.Font;

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.SwingUtilities;

public class TestTextArea {

    private void initUI() {
        JFrame frame = new JFrame("test");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JTextArea textArea = new JTextArea(24, 80);
        textArea.setFont(new Font("monospaced", Font.PLAIN, 12));
        frame.add(new JScrollPane(textArea));
        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new TestTextArea().initUI();
            }
        });

    }

}

Alternatively, you could look up a "free" font which meets your need, embed that font in with code and load it with java.awt.Font.createFont(int, InputStream).
