date format conversion

[memphisTNdev22]

Hey,

How may I be able to convert a date with the format of yyww with will be year and week, to a format of mmyy which will be month and year?

DateFormat df1 = new SimpleDateFormat("yyww");
DateFormat df2 = new SimpleDateFormat("MMyy");

//If your 'date' held in String var yourDate
//converted into String var mydate
String myDate = df2.format( df1.parse(yourDate) );

I don't know if this would work this simply. I haven't tried it, but it's got a reasonable chance.

(Oh, and you'll need to catch a ParseException from this code).

Notice on your locale of your system. I myself run JDK in Chinese system and i have to type chinese for the month.
If your locale uses English language, there is no problem

According to the API for SimpleDateFormat, it is locale-sensitive. Wouldn't it automatically cope with this, prosper?

How can you convert a week to a month?
A lot of weeks are part of two months.

I suspect, if it works at all, it'll consider the first day of the week as the date to convert. I know you don't like me assuming things, Stefan , but I just gave a quick reply and hoped the poster would try it and respond with another question if it didn't work.

@timw: Don't I?
My question 'how can you convert ...' was meant for memphisTNdev22 in the first place...

Perhaps there is a official convention for such conversions - well known in some communities like attorneys or accountants.

Very possibly. Memphis, would you like to comment at some point?
