java - 如何将 'dd/mm/yyyy hh:mm:ss am/pm' 转换为 hh :mm:ss (without am or pm) in java?

Question

我想将 1/15/2014 9:57:03 AM 或 1/15/2014 5:49:39 PM 之类的字符串转换为 9:57:03 和 17:49:39

Answer 1

SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss a", Locale.US);
Date date = format.parse("1/15/2014 9:57:03 AM");
format = new SimpleDateFormat("HH:mm:ss");
String dateString = format.format(date);

顺便说一句，下次使用谷歌
