SimpleDateFormat在解析时忽略月份

Question

下面的代码给出了解析日期为"Wed Jan 13 00:00:00 EST 2010"而不是"Wed Jun 13 00:00:00 EST 2010".任何想法都非常感激.

    SimpleDateFormat sf = new SimpleDateFormat("yyyy-mm-dd'T'HH:mm:ss");

    String str = "2010-06-13T00:00:00";

    Date date = sf.parse(str);

    System.out.println(" Date " + date.toString());

Answer 1

尝试:

"yyyy-MM-dd'T'HH:mm:ss"

MM意味着月份.mm分钟.有关SimpleDateFormat支持的日期和时间模式的更多详细信息,请参阅文档.

Answer 2

问题是您使用 'mm' 作为月份，而 'mm' 代表分钟。以下是所有可用的日期格式，请在此处阅读更多文档。
