Java如何获取本机MAC地址
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 {
/**
* @param args
* @throws UnknownHostException
* @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<mac.length; i++) {
if(i!=0) {
sb.append("-");
}
//字节转换为整数
int temp = mac&0xff;
String str = Integer.toHexString(temp);
System.out.println("每8位:"+str);
if(str.length()==1) {
sb.append("0"+str);
}else {
sb.append(str);
}
}
System.out.println("本机MAC地址:"+sb.toString().toUpperCase());
}
}
运行结果如下：
PC-201309011313/122.206.73.83
mac数组长度：6
每8位:d0
每8位:27
每8位:88
每8位:1f
每8位:89
每8位:51
本机MAC地址:D0-27-88-1F-89-51
