Getting fonts, sizes, bold,…etc

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
String[] fonts = ge.getAvailableFontFamilyNames();

The sizes and styles can be set at run-time.

E.G.

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

public class ShowFonts {

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
            String[] fonts = ge.getAvailableFontFamilyNames();
            JComboBox fontChooser = new JComboBox(fonts);
            fontChooser.setRenderer(new FontCellRenderer());
            JOptionPane.showMessageDialog(null, fontChooser);
        });
    }
}

class FontCellRenderer extends DefaultListCellRenderer {

    public Component getListCellRendererComponent(
            JList list,
            Object value,
            int index,
            boolean isSelected,
            boolean cellHasFocus) {
        JLabel label = (JLabel)super.getListCellRendererComponent(
                list,value,index,isSelected,cellHasFocus);
        Font font = new Font(value.toString(), Font.PLAIN, 20);
        label.setFont(font);
        return label;
    }
}
