輸出到控制臺當然是只能顯示為文本（調用對象的 toString() 方法并將其輸出），如果需要顯示 Image，考慮使用 Swing 中 JLabel 這樣的組件。

img = Toolkit.getDefaultToolkit().createImage(xp.asBytes());
JLabel lblImg = new JLabel(new ImageIcon(img));

// ... 將 JLabel 加入到 JFrame，并將 JFrame 顯示的代碼

public static BufferedImage toBufferedImage(Image image) {  
            if (image instanceof BufferedImage) {  
                return (BufferedImage)image;  
             }  
             image = new ImageIcon(image).getImage();  
             BufferedImage bimage = null;  
             GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();  
            try {  
                 
                int transparency = Transparency.OPAQUE;   
                 GraphicsDevice gs = ge.getDefaultScreenDevice();  
                 GraphicsConfiguration gc = gs.getDefaultConfiguration();  
                 bimage = gc.createCompatibleImage(  
                 image.getWidth(null), image.getHeight(null), transparency);  
             } catch (HeadlessException e) {  
             }  
            
            if (bimage == null) {   
                int type = BufferedImage.TYPE_INT_RGB;   
                 bimage = new BufferedImage(image.getWidth(null), image.getHeight(null), type);  
             }  
             Graphics g = bimage.createGraphics();  
             g.drawImage(image, 0, 0, null);  
             g.dispose();  
            
            return bimage;  
        }  

Image image=Toolkit.getDefaultToolkit().createImage(byte[] bytes);
         BufferedImage bufferedImage=toBufferedImage(image);
         try {
            ImageIO.write(bufferedImage, "JPG", new File("路徑"));
        } catch (IOException e) {
            e.printStackTrace();
        }
