In this post, we will learn how to get the MAC address and IP address of the machine using Java program
Java Code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 | import java.net.InetAddress; import java.net.NetworkInterface; import java.net.SocketException; import java.net.UnknownHostException; public class Code4example { public static void main(String[] args) throws SocketException{ InetAddress ip; try { ip = InetAddress.getLocalHost(); System.out.println("Current IP address : " + ip.getHostAddress()); NetworkInterface network = NetworkInterface.getByInetAddress(ip); byte[] mac = network.getHardwareAddress(); System.out.print("Current MAC address :" ); 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(sb.toString()); } catch (UnknownHostException e) { e.printStackTrace(); } catch (SocketException e){ e.printStackTrace(); } } } |
Output:
1 2 3 4 | Current IP address : 172.18.0.46 Current MAC address :02-42-AC-12-00-2E |
