Get MAC Address using Java
MAC Address can be obtained using the NetworkInterface class. This class represents a Network Interface made up of a name, and a list of IP addresses assigned to this interface. It is used to identify the local interface on which a multicast group is joined. A network interface is the point of interconnection between a computer and a private or public network.
code to get the MAC address
import java.net.InetAddress; import java.net.NetworkInterface; import java.net.SocketException; import java.net.UnknownHostException; public class MacAddress{ public static void main(String[] args){ try { InetAddress localhost = InetAddress.getLocalHost(); System.out.println("IP address : " + localhost.getHostAddress()); NetworkInterface network = NetworkInterface.getByInetAddress(localhost); 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) ? "-" : "")); } System.out.println("MAC address : "+sb.toString()); } catch (UnknownHostException e) { e.printStackTrace(); } catch (SocketException e){ e.printStackTrace(); } } }
output:-
IP address : 192.168.1.1 MAC address : 24-35-10-Z7-6H-17
