为什么写这个呢？因为前几天看见网上有采用windows命令获取局域网和广域网MAC，查了查可以直接用JDK的方法。
MAC可用于局域网验证，提高安全性。
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
/*
* 物理地址是48位，别和ipv6搞错了

public class LOCALMAC {
/**

* @throws SocketException
*/
public static void main(String[] args) throws UnknownHostException, SocketException {
// TODO Auto-generated method stub
//得到IP，输出PC-201309011313/122.206.73.83
InetAddress ia = InetAddress.getLocalHost();
System.out.println(ia);
getLocalMac(ia);
}
private static void getLocalMac(InetAddress ia) throws SocketException {
// TODO Auto-generated method stub
//获取网卡，获取地址
byte[] mac = NetworkInterface.getByInetAddress(ia).getHardwareAddress();
System.out.println("mac数组长度："+mac.length);
StringBuffer sb = new StringBuffer("");
for(int i=0; i |
