通過招執行系統命令取得MAC地址

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
public class GetMacAddress
{
static void doExe()
{
try
{
Runtime runtime=Runtime.getRuntime();
//采用這種方式就會將結果輸出到一個文件中去
//String[] args=new String[]{"CMD.EXE","/c","ipconfig /all>e:\\456.txt"};
String[] args=new String[]{"CMD.EXE","/c","ipconfig /all"};
//執行系統命令
Process p=runtime.exec(args);
//取得出入流
InputStream is=p.getInputStream();
InputStreamReader isr=new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
//將輸入流讀出來顯示在屏幕上
while((line=br.readLine())!=null)
{
//去掉下面的注釋打印全部信息到屏幕
/*
if(!line.trim().equals(""))
System.out.println(line);
*/
//對指定的輸入流進行處理
if(line.trim().startsWith("Physical Address"))
{
line=line.trim();
String[] r=line.split(":");
System.out.println("MAC ADDRESS:"+r[1].trim());
}
}
is.close();
isr.close();
br.close();
}
catch(Exception e){e.printStackTrace();}
}
public static void main(String[] args)
{
doExe();
}
}
