public void getHost(){
    try {
        InetAddress inetAddr = InetAddress.getLocalHost();
        byte[] addr = inetAddr.getAddress();
        // Convert to dot representation
        String ipAddr = "";
        for (int i = 0; i < addr.length; i++) {
            if (i > 0) {
                ipAddr += ".";
            }
            ipAddr += addr[i] & 0xFF;
        }
        System.out.println(ipAddr);
    } catch (UnknownHostException e) {
        System.out.println("Host not found: " + e.getMessage());
    }
