Java：从Java运行批处理脚本时检测用户提示

那应该做的工作：

  public static void main(final String... args) throws IOException, InterruptedException {    final Runtime runtime = Runtime.getRuntime();    final String command = "..."; // cmd.exe    final Process proc = runtime.exec(command, null, new File("."));    final BufferedReader input = new BufferedReader(new InputStreamReader(proc.getInputStream()));    StringBuilder sb = new StringBuilder();    char[] cbuf = new char[100];    while (input.read(cbuf) != -1) {        sb.append(cbuf);        if (sb.toString().contains("Password:")) { break;        }        Thread.sleep(1000);    }    System.out.println(sb);}
