    If your using linux, use nmap.
    This lists all IP addresses and Mac addresses of the Given Ip Address

    But Il need more info than that.
    Theres a java command to get host name so im guessing that there will be a command to get MAC address

    Also people aren't just going to give you the code. you will have to try a little bit

    I didn't write this. A quick Google search provides many results. For example:

    import java.net.InetAddress;
    import java.net.NetworkInterface;
    public class Main {
      public static void main(String[] args) throws Exception {
        InetAddress address = InetAddress.getLocalHost();
        NetworkInterface ni = NetworkInterface.getByInetAddress(address);
        byte[] mac = ni.getHardwareAddress();
        for (int i = 0; i < mac.length; i++) {
          System.out.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : "");
