reciveing value from the thread

Dear friends , i have a small issue i am working on j2me code , i have
to develop a class that will receive the message . From the main
program when the user hits the required button a function from "
messagereciving " class will be called , the only thing is that ,
function receiving code is inside the run method , the value of the
recieved msg text is inside the variable "msgReceived" i have to get
this value in the main method , the source code of message receiving
class is as follows :

import javax.microedition.io.*;
import javax.wireless.messaging.*;
import java.io.IOException;

public class SMSMIDlet implements Runnable {
    private Thread mReceiver = null;
    private String mPort = "1234";
    public String msgReceived = null;
    public SMSMIDlet() {
    }
    private void startReceive() {
        if (mReceiver != null)
            return;
        // start receive thread
        mReceiver = new Thread(this);
        mReceiver.start();
    }
    private boolean mEndNow = false;
    private MessageConnection conn = null;
    public void run() {
        Message msg = null;

        conn = null;
        mEndNow = false;
        /** Check for sms connection. */
        try {
            conn = (MessageConnection) Connector.open("sms://:" +
mPort);
            msg = conn.receive();
            while ((msg != null) && (!mEndNow)) {

                if (msg instanceof TextMessage) {

                    msgReceived = ((TextMessage)msg).getPayloadText();
                    // i have to get the value of msgReceived in the
calling program
                  }
            }
        } catch (IOException e) {

        }
    }

}
