I am actually trying to print the mac addresses of the machine on which my web app is deployed. I have seen many questions related to mac addresses on SO, but I couldn't solve my issue. I have tried so far with the following code:
public static void main(String[] args) {
getMac();
}
public static void getMac() {
List<String> list = new ArrayList<String>();
try {
Enumeration<NetworkInterface> networks = NetworkInterface.getNetworkInterfaces();
while (networks.hasMoreElements()) {
NetworkInterface network = networks.nextElement();
byte[] mac = network.getHardwareAddress();
if (mac != null) {
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++) {
sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
}
if (!(sb.length() == 0) && !list.contains(sb.toString())) {
if (!sb.toString().equals("00-00-00-00-00-00-00-E0")) {
list.add(sb.toString());
}
}
}
}
} catch (SocketException e) {
e.printStackTrace();
}
System.out.println("Mac Adresses List = " + list);
}
The code actually lists all the network interface mac addresses including virtual adapters. However I want to know if there is a way to find out the mac address of only those devices which exist on the machine. I have seen this post but it is not related to java. I want this information to uniquely identify a computer(though there are limitations with this approach).
