How to create a Date with specific format in Java?
提问by Adham
I have the following code to handle date
我有以下代码来处理日期
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss a");
String s = formatter.format(formatter.parse("10/11/2011 4:24:00 PM");
System.out.prinln(s);
Date d = (Date)formatter.parseObject(s);
System.out.println(d);
this first print line output is : 10/10/2011 00:00:00 AM
第一个打印行输出是： 10/10/2011 00:00:00 AM
and the second is : Mon Oct 10 00:00:00 GMT+02:00 2011
第二个是： Mon Oct 10 00:00:00 GMT+02:00 2011
How I can make the second statement print out the same as the first one?
如何使第二个语句打印出来与第一个语句相同？

回答by Bozho
You can't. The toString()method of objects is used mainly for debugging, and not for presenting to users.
你不能。toString()对象的方法主要用于调试，不用于呈现给用户。
Always use a formatter. In your case: String formatted = formatter.format(d)
始终使用格式化程序。在你的情况下：String formatted = formatter.format(d)
The Dateobject does not have a representation format. It only has the data. The formatter has the format.
该Date对象不具有代表性的格式。它只有数据。格式化程序有格式。
