请教process.getInputStream()的问题

Java code

Process process = Runtime.getRuntime().exec ("cmd.exe");               BufferedReader   bufferedReader   =   new   BufferedReader(   new   InputStreamReader(process.getInputStream()));                      String line;                   while ((line = bufferedReader.readLine ()) != null)               {                 System.out.println(line);                 System.out.flush();                }

在while ((line = bufferedReader.readLine ()) != null) 时前两行可以输出，
Microsoft Windows XP [版本 5.1.2600]

再往下到了while ((line = bufferedReader.readLine ()) != null) 的时候就不动了，程序就卡在那里了，请问这是怎么回事？谢谢啦


[解决办法]
你在循环的的最后面应该在让他读一遍！
