Read(Load)/Write(Save) Problem

Question

I have a form that is filled out by people and I want to save the information in a text file. I have done that well at least I think with the Save code. My problem is when I go to load the text file (.CMM file for my program), nothing happens but it does print out my File Loaded message in the console. Any idea where I am missing something? The getter and setter methods all seem to be correct...
private void SavePrefs() {
          File SavePrefs;
          // get filename:
          fc.setDialogTitle("Select Filename For Site Data");
          int result = fc.showSaveDialog(f);
          if (result == JOptionPane.OK_OPTION) {
               SavePrefs = fc.getSelectedFile();
               // default file extension ".CMM"
               if (!SavePrefs.getName().endsWith(".CMM")) {
                    // filename does not meet requirements:
                    System.out.println("NO CMIMS in filename");
                    SavePrefs = new File(SavePrefs.getAbsolutePath() + ".CMM");
               // continue with save code:
               System.out.println("File Selected:" + SavePrefs.toString());
               //Creates a .cmm file with all the data in it.
               FileOutputStream saveData;
               PrintStream data;
               try {
                    saveData = new FileOutputStream(SavePrefs.toString());
                    data= new PrintStream(saveData);
                    data.println("CLOSE YEAR="+_SitePropPanel.getCloseYear());
                    data.println("OPEN YEAH="+_SitePropPanel.getOpenYear());
                    //data.println("COL RATE = "+_SitePropPanel.getCollectionRate());
                    data.println("GAS RECOV STATE="+_SitePropPanel.getGasRecoveryState());
                    data.println("SITE CLOSED="+_SitePropPanel.getLandfillClosed());
                    data.flush();
                    data.close();
                    saveData.flush();
                    saveData.close();
               } catch (FileNotFoundException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
               } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
               System.out.println("File Saved");
          // not OK selected (cancel or.?)
     private void LoadPrefs() {
          File loadPrefs;
          // get filename:
          fc.setDialogTitle("Select Filename For Site Data");
          int result = fc.showOpenDialog(f);
          if (result == JOptionPane.OK_OPTION) {
               loadPrefs = fc.getSelectedFile();
               // default file extension ".CMM"
               if (!loadPrefs.getName().endsWith(".CMM")) {
                    // filename does not meet requirements:
                    System.out.println("NO CMIMS in filename");
               // continue with save code:
               System.out.println("File Selected:" + loadPrefs.toString());
               Properties loadData = new Properties();
               try {
                    loadData.load( new FileReader( loadPrefs.toString() ) );
                    _SitePropPanel.setLandfillClosed(new Boolean(loadData.getProperty("SITE CLOSED")));
                    _SitePropPanel.setCloseYear(loadData.getProperty("CLOSE YEAR"));
                    _SitePropPanel.setOpenYear(loadData.getProperty("OPEN YEAR"));
                    //_SitePropPanel.setCollectionRate(loadData.getProperty("COL RATE"));
                    _SitePropPanel.setGasRecoveryState(new Boolean(loadData.getProperty("GAS RECOV STATE")));
               } catch (FileNotFoundException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
               } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
               System.out.println("File Loaded");
     }

Hi sch,
i've been figuring out what is the problem and i think i found it.
Your saving the data with this.
data.println("CLOSE YEAR="+_SitePropPanel.getCloseYear());
data.println("OPEN YEAH="+_SitePropPanel.getOpenYear());
//data.println("COL RATE = "+_SitePropPanel.getCollectionRate());
data.println("GAS RECOV STATE="+_SitePropPanel.getGasRecoveryState());
data.println("SITE CLOSED="+_SitePropPanel.getLandfillClosed());
when trying to System.out the loadData (properties) you can see clearly that it prints out like this
CLOSE=YEAR, OPEN=YEAH, etc etc
so obvouisly your not setting correctly.
it works this way.
