问题描述

我正在尝试将格式为yyyy-MM-dd HH:mm:ss"的日期转换为dd-MM-yyyy".

I am trying to convert date which is in string and got format of "yyyy-MM-dd HH:mm:ss" to "dd-MM-yyyy".

我已经实现了以下代码,但它给出了:java.lang.IllegalArgumentException

I have implmented following code but its giving : java.lang.IllegalArgumentException

        SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
        Date date = new Date(values);
        String mydate = dateFormat.format(date);

推荐答案

首先,您必须将日期时间的字符串表示形式解析为 Date 对象.

First you have to parse the string representation of your date-time into a Date object.

DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = (Date)formatter.parse("2011-11-29 12:34:25");

然后您将 Date 对象格式化回您喜欢的格式的字符串.

Then you format the Date object back into a String in your preferred format.

DateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
String mydate = dateFormat.format(date);
