My thread will not start

I have my thread class (which transmits a datagram):

Code:

---


public class heartbeat extends Thread {

        private int portNum;
        private InetAddress address;
        private int siteNum;


        public heartbeat(InetAddress pAddress, int pPortNum, int pSiteNum)
        {
                portNum = 3001;
                address = pAddress;
                siteNum = pSiteNum;

        }

        public void Run()
        {
                byte[] buf = new byte[256];

                String stringToSend = "[H," + siteNum + "]";
                buf = stringToSend.getBytes();
                System.out.println("Port is " + portNum);

                try {
                        DatagramSocket socket = new DatagramSocket(portNum);
                        DatagramPacket packet = new DatagramPacket(buf, buf.length, address, portNum);

                        while(true)
                        {
                                System.out.println(stringToSend);
                                socket.send(packet);
                        }
                } catch (Exception e)
                { System.exit(0); }

        }

}

---

and then the following two lines in my main program.

Code:

---

                  heartbeat myHeartbeat = new heartbeat(serverAddr, serverPort, siteID);
                  myHeartbeat.start();

---

It all looks right to me but the thread will not run and I can't see whats wrong with it!! Please help.

Capitalization.

public void run() overrides the run method

public void Run() makes a new method that doesn't override it.

change your Run into run() instead

In the future use the @Override statement before methods that are overrides. The compiler will then tell you if your method is NOT overriding anything.

Change public void Run()
to
public void run()
