Get MAC address on local machine with Java
java, mac-address, sockets
Solution
With Java 6+, you can use `NetworkInterface.getHardwareAddress`.
Bear in mind that a computer can have no network cards, especially if it's embedded or virtual. It can also have more than one. You can get a list of all network cards with `NetworkInterface.getNetworkInterfaces()`.
Problem
I can use ``` ip = InetAddress.getLocalHost(); NetworkInterface.getByInetAddress(ip); ``` to obtain the mac address, but if I use this code in an offline machine it doesn't work. So, How can I get the Mac address?
