Your code does not contain the code to actually create a file. You should look at [Java Tutorial: Basic I/O](http://docs.oracle.com/javase/tutorial/essential/io/) for examples. — Oleg Estekhin, Apr 30 '14 at 07:40
The only thing you do in your `Save` `ActionListener` is to set the `filename` and `dir` text fields in your UI, you should make a call to actually write the file as @OlegEstekhin suggested. — Patru, Apr 30 '14 at 07:43
Java GUIs might have to work on a number of platforms, on different screen resolutions & using different PLAFs. As such they are not conducive to exact placement of components. To organize the components for a robust GUI, instead use layout managers, or [combinations of them](http://stackoverflow.com/a/5630271/418556), along with layout padding & borders for [white space](http://stackoverflow.com/q/17874717/418556). — Andrew Thompson, Apr 30 '14 at 07:49

In your actionPerformed method, you do not actually save the file. You just store its name and folder to variables.

Using JfileChooser you can get the path. And after that you can copy what you want to that location.

here is the sample code

   jFileChooser1.setDialogType(javax.swing.JFileChooser.SAVE_DIALOG);

    jFileChooser1.setFileSelectionMode(javax.swing.JFileChooser.DIRECTORIES_ONLY);

    final int fd = jFileChooser1.showDialog(null, "Select folder to save.");

    if (fd == JFileChooser.APPROVE_OPTION) {

        /*you can write the code in here */

        String setBackUpFolderName = setBackUpFolderName(iivo);
        try {
            saveDataToFileExcel(setBackUpFolderName, iivo);
        } catch (Exception ex) {
            Logger.getLogger(ExcelTest.class.getName()).log(Level.SEVERE, null, ex);
        }

    } else {
        // this.dispose();
    }
