将字符串解析为Date对象

Question

I have string "Tue Nov 12 2010",I want to parse it in java.util.Date object. I write below code for this

DateFormat format = new SimpleDateFormat("dd/MM/yyyy");
Date date= format.parse("Tue Nov 12 2010");

It is giving exception like below:

java.text.ParseException: Unparseable date: "Sun Nov 21 2010"

Not getting what is wrong with it???

Answer 1

您的格式错误 - 如果您指定格式dd/MM/yyyy ，那么您需要提供要以相应格式（！）格式化的字符串，例如21/11/2010 。

Answer 2

Ofcourse because it is not in format

format for Tue Nov 12 2010 should be EEE MMM dd yyyy

Have a look at docs

Answer 3

Learn to read code and use common sense.

DateFormat format = new SimpleDateFormat("dd/MM/yyyy");
Date date= format.parse("Tue Nov 12 2010");

This should be blatantly obvious that the format specified doesn't match the string being parsed. They're on adjacent lines, right next to each other. It doesn't get more straightforward than that.

You need to be able to see something like this if you are to be a successful programmer. If you can't see this, how are you ever going to find similar problems when the two lines causing problems aren't even in the same source code file?

My advice is to take some personal responsibility for learning how to read and debug code. Something like this should be a huge red flag right when you type it that the two lines of code don't match up.

Answer 4

The date format you have created
new SimpleDateFormat("dd/MM/yyyy");
Will only parse dates of that form. Ie 05/10/1989 You'll need to change the format something more appropriate.

Answer 5

To parse the date you need to provide correct format. For the sample date give by you the format would be "EEE MMM dd yyyy"

Answer 6

You are using the wrong format for the date. To parse it according to your string format use "EEE MMM dd yyyy"
