利用Java擷取本機mac地址

public static void getAllMacAdress() {        Enumeration<NetworkInterface> netInterfaces = null;         try {            // 獲得所有網路介面            netInterfaces = NetworkInterface.getNetworkInterfaces();            while (netInterfaces.hasMoreElements()) {                System.out                        .println("==============================================");                String mac = "";                StringBuffer sb = new StringBuffer();                NetworkInterface ni = netInterfaces.nextElement();                System.out.println("DisplayName: " + ni.getDisplayName());                System.out.println("Name: " + ni.getName());                 byte[] macs = ni.getHardwareAddress();                // 該interface不存在HardwareAddress，繼續下一次迴圈                if (macs == null) {                    continue;                }                 for (int i = 0; i < macs.length; i++) {                    mac = Integer.toHexString(macs[i] & 0xFF);                    if (mac.length() == 1) {                        mac = '0' + mac;                    }                    sb.append(mac + "-");                }                mac = sb.toString();                mac = mac.substring(0, mac.length() - 1);                System.out.println(mac);                 Enumeration<InetAddress> ips = ni.getInetAddresses();                while (ips.hasMoreElements()) {                    System.out.println("IP: "                            + ips.nextElement().getHostAddress());                }            }        } catch (SocketException e) {            e.printStackTrace();        }    }

本方法需要使用使用jdk1.6
