convert day of week

[Michael Sampson]

Now I have other ways of doing this but I was trying not to clutter up code. I am looking for an elegant way to do this. I have a string "MON", which I would to become "Monday". Is there some already written static routine in java that can do this. I have looked at the Calendar class a bit but this is not what it is designed for. I am thinking I will just have to write my own class. Well there probably is a way to get it out of Calendar but it's probably some formatting trick. Any ideas?

Check out DateFormat and its subclass SimpleDateFormat. In essence, you do the following:
- create a (Simple)DateFormat that will only use the day of week
- use its parse method to create a Date
- use its format method to turn it back into the week day String
In short code:

DateFormat format = new SimpleDateFormat("??"); // fill in the pattern yourself
String weekDay = format.format(format.parse("MON"));

You'll have to experiment a bit with repeating the day of the week pattern symbol; if you repeat it enough it will work the way you want.
