Re: [問題] 取得MacAddress

[cphunter (克理斯@Internet)]

用 macbook 跑了一下 ， 並且我是預設不知道 interface 的名稱


import java.net.*;
import java.util.Enumeration;
public class
GetHardwareAddress {
    /**
    * @param 取得 mac address
    */
 public static void main(String args[]) throws Exception {
  Enumeration interfaces = NetworkInterface.getNetworkInterfaces();

  while (interfaces.hasMoreElements()) {
   NetworkInterface ni = (NetworkInterface) interfaces.nextElement();
   NetworkInterface networkInterface = NetworkInterface.getByName(ni.getName());
   byte b1[] = networkInterface.getHardwareAddress();

  System.out.print("Hardware Address = ");
   if (b1!=null)
    for (int i = 0; i < b1.length; i++)
       System.out.print(b1[i]);
   } //end while , quit interfaces.hasMoreElemetns()
 }
}
