Java에서 글꼴, 크기 및 스타일에 어떻게 액세스하고 조작합니까?

<code class="java">GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
String[] fonts = ge.getAvailableFontFamilyNames();</code>

<code class="java">Font font = new Font("Arial", Font.BOLD, 12);</code>

<code class="java">font.setBold(true);
font.setSize(14);</code>

<code class="java">import java.awt.*;
import javax.swing.*;

public class FontDemo {

    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 {

    @Override
    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;
    }
}</code>
