问题描述

我要格式化的字符串如下所示:字符串日期时间 = "9/1/10 11:34:35 AM"

The string I want to format looks like this: String datetime = "9/1/10 11:34:35 AM"

SimpleDateFormat 的以下模式有效:

Following pattern for SimpleDateFormat works:

SimpleDateFormat sdf = SimpleDateFormat("M/d/yy h:mm:ss");
Date d = sdf.parse(datetime);
System.out.println(d);

Output> [Wed Sep 01 11:34:35 CEST 2010]

但是我也需要解析 AM/PM 标记,当我将它添加到模式时,我收到一个异常.

However I need to parse the AM/PM marker as well, and when I add that to the pattern I receive an exception.

不起作用的模式:

SimpleDateFormat sdf = SimpleDateFormat("M/d/yy h:mm:ss a");

我也试过这个,但有同样的例外:

I have tried with this also with same exception:

SimpleDateFormat sdf = SimpleDateFormat("M/d/yy h:mm:ss aa");

异常:

java.text.ParseException: Unparseable date: "9/1/10 11:34:35 AM"

我浏览了 http://download.oracle.com/javase/1.4.2/docs/api/java/text/SimpleDateFormat.html#text 但似乎找不到我做错的地方.

I have looked through the API at http://download.oracle.com/javase/1.4.2/docs/api/java/text/SimpleDateFormat.html#text but canät seem to find where I do wrong.

有什么建议吗?

推荐答案

一种可能性是您的默认 Locale 具有不同的 AM/PM 符号.在构建日期格式时,您应该始终提供 Locale,除非您确实想使用系统默认的 Locale,例如:

One possibility is that your default Locale has different symbols for AM/PM. When constructing a date format you should always supply a Locale unless you really want to use the system's default Locale, e.g.:

SimpleDateFormat sdf = new SimpleDateFormat("M/d/yy h:mm:ss a", Locale.US)
