Saving Records with RMS

Question

Hi,
I'm totally new to RMS, so I want to post a question, which is maybe easy for u but very diffucult for me.
So I want to set up a recordstore (i.e. Data).
Data has 3 attributes: NAME, DESC, ADRESS.
Is it possible to save this information in one record?
I thought about adding a class with these attributes, but I didn't know how to add an object of this class in a record.
I'm very thankful for any help ideas etc. I can get.

P.S. Sorry for my english!

This is an example of use RMS.
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import javax.microedition.rms.*;
import java.io.*;
public class RMSDemo extends MIDlet implements CommandListener {
    private Display display;
    private RecordStore rs=null;
    private Command exit;
    private RecordEnumeration re;
    private int recordNO;
    Form frm;
    int index=0;
    public RMSDemo() {
        display = Display.getDisplay(this);
        //Create a RMS
        try {
            rs= RecordStore.openRecordStore("myRecord",false);
            rs.closeRecordStore();
        } catch(Exception e) {
            System.out.println(e);
    public void startApp()   {
        frm=new Form("RMSDemo");
        exit= new Command("Exit",Command.EXIT,1);
        frm.addCommand(exit);
        add= new Command("Add",Command.SCREN,1);
        frm.addCommand(add);
        delete= new Command("Delete",Command.SCREEN,2);
        frm.addCommand(delete);
        show= new Command("SHOW",Command.SCREEN ,3);
        frm.addCommand(show);
        frm.setCommandListener(this);
        frm.append("#####");
        display.setCurrent(frm);
    public void pauseApp() {
    public void destroyApp(boolean un) {
    // Handling commands
    public void commandAction(Command cmd,Displayable d) {
        if(cmd==add) {
            addRecord();
        } else
            if(cmd==delete) {
            removeRecord();
            } else
                if(cmd==show) {
            try {
                byte b[]= rs.getRecord(recordNO);
                String s= new String(b);
                frm.append(s);
            } catch(Exception e) {}
    void addRecord() {
        try {
            rs= RecordStore.openRecordStore("myRecord",false);
            index++;
            byte b[]=("Record NO "+index).getBytes();
            //Adding record to record store
            rs.addRecord(b,0,b.length);
            rs.closeRecordStore() ;
        } catch(Exception e) {
            System.out.println(e);
    // Deleting a record
    void removeRecord(int recordID) {
        try {
            rs= RecordStore.openRecordStore("myRecord",false);
            rs.deleteRecord(recordID);
            index--;
            rs.closeRecordStore();
        } catch(Exception e) {
            System.out.println(e);
}
