如何正确地将字节绘制到JFrame

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

class BytePanel extends JPanel {
    private byte[] bytes;

    public void setBytes(byte[] bytes) {
        this.bytes = bytes;
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        if (bytes != null) {
            String text = new String(bytes);
            g.drawString(text, 50, 50);
        }
    }
}

public class ByteDrawingExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("绘制字节到JFrame");
        frame.setSize(500, 500);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        BytePanel bytePanel = new BytePanel();
        frame.add(bytePanel);

        byte[] bytes = "Hello, World!".getBytes();
        bytePanel.setBytes(bytes);
        bytePanel.repaint();

        frame.setVisible(true);
    }
}
