推荐答案

    int returnValue = jFileChooser1.showOpenDialog(this);//Crate a filechoser
    jFileChooser1.setVisible(true);//SetVisible

if (returnValue == JFileChooser.APPROVE_OPTION) {
    File file = jFileChooser1.getSelectedFile();//Get the file
    ImageIcon icon = new ImageIcon();//Icon Constructor
     try {
            BufferedImage image = ImageIO.read(file); // Read File(Image)
         }
     catch (IOException ex)
     {
                  //For Exceptions
     }
     ImageIcon image = new ImageIcon(file.getPath());
     lblresim.setIcon(image); //Set the label with the file that was taken via filechooser

} else {
   JOptionPane.showMessageDialog(null,"File Choosing cancelled by user.");//If no file taken from FileChoser warn user.
}
}
