I am developing an image editing app, so want to display an image selected by JFileChooser, so what would be best approach so that it can display all formats jpg, png, gif etc. OpenButton is used for invocation of filechooser.

private void OpenActionPerformed(java.awt.event.ActionEvent evt) {
       int returnVal = fileChosser.showOpenDialog(this);
       if (returnVal == JFileChooser.APPROVE_OPTION) {
           File file = fileChosser.getSelectedFile();
           // What to do with the file
           // I want code for this part
           try {
             //code that might create an exception 
           } 
           catch (Exception e1) {
             e.printStackTrace();
           }
       }
}
