Save File

I write simple editor using Jfram , java GUI , one of the function is to open file , when the user open the file he or she want to edit the file , then he \ she choose save

the problem is here , I want to save the opened file on the same opened file without asking me gain to choose name for the file

thankyou in advanced ,

for save action I reuse this method

class SaveAction extends AbstractAction {
    public SaveAction() {
      super("Save", new ImageIcon("icons/save.gif"));
    }

    // Query user for a filename and attempt to open and write the text
    // component's content to the file.
    public void actionPerformed(ActionEvent ev) {
      JFileChooser chooser = new JFileChooser();
      if (chooser.showSaveDialog(Main.this) != JFileChooser.APPROVE_OPTION)
        return;
      File file = chooser.getSelectedFile();
      if (file == null)
        return;

      FileWriter writer = null;
      try {
        writer = new FileWriter(file);
        textComp.write(writer);
      } catch (IOException ex) {
        JOptionPane.showMessageDialog(Main.this,
            "File Not Saved", "ERROR", JOptionPane.ERROR_MESSAGE);
      } finally {
        if (writer != null) {
          try {
            writer.close();
          } catch (IOException x) {
          }
        }
      }
    }
  }

Open in new window

If you want to save to the same file you doen't need to use filechooser and don't need to instantite it
here. Do you have two button - one to save to the same file, another to "save as" ?

for_yan

If you want to save to the same file from which you reda you should already tknow the file
so just removve this part

JFileChooser chooser = new JFileChooser();
if (chooser.showSaveDialog(Main.this) != JFileChooser.APPROVE_OPTION)
return;
File file = chooser.getSelectedFile();
if (file == null)
return;

and make sure you pass the File or filename to thios method,
You'll need to have this file closed and then opened again for wtriting
