‘壹’ java怎么生成本机mac地址

来走一个

publicstaticvoidmain(String[]args)throwsUnknownHostException,SocketException{
InetAddressinetAddress=InetAddress.getLocalHost();
//获取网卡，获取地址
byte[]mac=NetworkInterface.getByInetAddress(inetAddress).getHardwareAddress();
StringBuffersb=newStringBuffer("");
for(inti=0;i<mac.length;i++){
if(i!=0){
sb.append("-");
}
//字节转换为整数
inttemp=mac[i]&0xff;
Stringstr=Integer.toHexString(temp);
if(str.length()==1){
sb.append("0"+str);
}else{
sb.append(str);
}
}
System.out.println("本机MAC地址:"+sb.toString().toUpperCase());
}

输出:

本机MAC地址:B8-88-E3-FA-03-39

‘贰’ java中怎么获取电脑的mac地址

importjava.net.InetAddress;

importjava.net.NetworkInterface;

importjava.net.SocketException;

importjava.net.UnknownHostException;


/*

*物理地址是48位，别和ipv6搞错了

*/

publicclassLOCALMAC{


	/**

	*@paramargs

	*@throwsUnknownHostException

	*@throwsSocketException

	*/

	publicstaticvoidmain(String[]args)throwsUnknownHostException,SocketException{

		//TODOAuto-generatedmethodstub

		

		//得到IP，输出PC-201309011313/122.206.73.83

		InetAddressia=InetAddress.getLocalHost();

		System.out.println(ia);

		getLocalMac(ia);

	}


	privatestaticvoidgetLocalMac(InetAddressia)throwsSocketException{

		//TODOAuto-generatedmethodstub

		//获取网卡，获取地址

		byte[]mac=NetworkInterface.getByInetAddress(ia).getHardwareAddress();

		System.out.println("mac数组长度："+mac.length);

		StringBuffersb=newStringBuffer("");

		for(inti=0;i<mac.length;i++){

			if(i!=0){

				sb.append("-");

			}

			//字节转换为整数

			inttemp=mac[i]&0xff;

			Stringstr=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());

	}

}
