我想建议一个更简单的方法，

I'd like to suggest a more simple way,

  image = ImageIO.read(new File(path));
  JLabel picLabel = new JLabel(new ImageIcon(image));

耶耶！现在您的图像是一个摆动组件！将它添加到框架或面板或您通常做的任何东西！可能也需要重新粉刷，比如

Yayy! Now your image is a swing component ! add it to a frame or panel or anything like you usually do! Probably need a repainting too , like

  jpanel.add(picLabel);
  jpanel.repaint();
