java - SimpleDateFormat 显示提取日期的日期值错误

Question

我试图从 DateTime 字符串中单独提取日期和时间，但代码显示错误的日期。

代码

    String dateTime= "2015-12-10T14:00:00";
    SimpleDateFormat frm1 = new SimpleDateFormat("YYYY-MM-dd'T'HH:mm:ss");
    Date date = frm1.parse(dateTime);
    SimpleDateFormat frm2 = new SimpleDateFormat("dd/MM/YYYY");
    String date1 = frm2.format(date);
    System.err.println(date1);
    SimpleDateFormat frm3 = new SimpleDateFormat("HH:mm");
    String time = frm3.format(date);
    System.err.println(time);

输出

28/12/2015
14:00
