我有一个包含此内容的文本文件
08:00 - 09:30
09:45 - 11:15
11:30 - 13:00
08/04/13
14:00 - 15:30
15:45 - 17:15
17:30 - 19:00
MIS (CH27) UM
MIS (CH27) UM
每条空线对应一周中的一天，08/04/14 是一周的第一天。我想读取文本文件，计算 MIS 发生的日期并打印出来。这是我的程序，它在结果中什么也没显示。

cal.setTime(date); // Sets this Calendar's time with the given Date.
}

if ((in.readLine()) == " ") {
cal.add(Calendar.DAY_OF_MONTH, 1);
}
else {
if (line.matches("MIS")) {
String fday = dateFormat.format(cal.getTime());
System.out.println((fday));
System.out.println(line);
}
}

in.close();

catch (IOException e) {

有人能指出我哪里做错了吗！清你！
