楼主的意思也就是说用java来实现对外部应用程序的调用。你可以用runtime类中的exec方法去实现！
public class macaddress {
  public static void main(String[] args) {
    macaddress mdd = new macaddress();
    String str=mdd.getMessageOnWindow();
    System.out.println(str);
  }
  private static String getMessageOnWindow() {
        String s = "";
        try {
            String s1 = "ping 127.0.0.1";
            Process process = Runtime.getRuntime().exec(s1);
            BufferedReader bufferedreader = new BufferedReader(
                    new InputStreamReader(process.getInputStream()));            String str=reader.readLine();
          while (str!=null)
      {
        System.out.println(str);
        str=reader.readLine();
      }
      
            
            bufferedreader.close();
            process.waitFor();
        } catch (Exception ex) {
             ex.printStackTrace();
            }
        
}
