InetAddress ip = InetAddress.getLocalHost();

System.out.println("IP:"+ip);

NetworkInterface network = NetworkInterface.getByInetAddress(ip);

byte[] mac = network.getHardwareAddress();

StringBuilder sb = new StringBuilder();

for (int i = 0; i < mac.length; i++) {sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));

}

String hostMac=sb.toString();

System.out.println("Current MAC address : "+hostMac);
