Format Dates Using SimpleDateFormat

Hi everyone,

My programming class just started and we're learning Java. Here is the challenge our teacher gave us:

> build a date de-assembler from scratch
> takes today’s date and display it separately in dialog windows (JDialog): year, month (the name of the month, NOT the number), day, hour, minutes, seconds, milliseconds
> ADVANCED : do this using only ONE SimpleDateFormat Object

My problem is the advanced part. Since I'm such a newbie with it, I copy and pasted most of it so it would work the way he wanted. There might be a much simpler way, but since I'm so new to Java, we haven't really learned how to get rid of redundancy.

Anyone have any pointers on the advanced part? I'm not necessarily looking for the answers, although that would be nice, I won't even lie. I've been looking online and in the Java API for hints and cannot find it. Anyway, my code is below for the first part, but the advanced part, I cannot figure out!
