Answer 1

publicstaticBufferedImagetoBufferedImage(Imageimage){
if(imageinstanceofBufferedImage){
return(BufferedImage)image;
}
image=newImageIcon(image).getImage();
BufferedImagebimage=null;
GraphicsEnvironmentge=GraphicsEnvironment.getLocalGraphicsEnvironment();
try{
inttransparency=Transparency.OPAQUE;
GraphicsDevicegs=ge.getDefaultScreenDevice();
GraphicsConfigurationgc=gs.getDefaultConfiguration();
bimage=gc.createCompatibleImage(
image.getWidth(null),image.getHeight(null),transparency);
}catch(HeadlessExceptione){
}
if(bimage==null){
inttype=BufferedImage.TYPE_INT_RGB;
bimage=newBufferedImage(image.getWidth(null),image.getHeight(null),type);
}
Graphicsg=bimage.createGraphics();
g.drawImage(image,0,0,null);
g.dispose();
returnbimage;
}
Imageimage=Toolkit.getDefaultToolkit().createImage(byte[]bytes);
BufferedImagebufferedImage=toBufferedImage(image);
try{
ImageIO.write(bufferedImage,"JPG",newFile("路径"));
}catch(IOExceptione){
e.printStackTrace();
}

输出到控制台当然是只能显示为文本（调用对象的toString()方法并将其输出），如果需要显示Image，考虑使用Swing中JLabel这样的组件。
img=Toolkit.getDefaultToolkit().createImage(xp.asBytes());
JLabellblImg=newJLabel(newImageIcon(img));
//...将JLabel加入到JFrame，并将JFrame显示的代码
