ProcessBuilder pb = new ProcessBuilder("cmd", "/c", "dir", "c:"); Process p = pb.start(); BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream(), "gbk")); String line; 和其他系统命令不一样，“dir” is built-in to the windows shell (cmd.exe) and can't be run as a simple executable “ipconfig /all”命令就可以直接运行
