Use the String.toUpperCase() method.

why not just upper case your 'MMM' result ?

---

With the SimpleDateFormat class you cannot or use String.toUpperCase() (as said Ben J) in conjunction with the "MMM".

This makes sense if you work with dates but if you just work with numbers (ie: 4) you can build a complete switch statement on the number...

Use String.subString and then apply String.toUpperCase to get desired result.
