/*
GOAL: Create two files, odds.txt and evens.txt, with the
first one containing the odd numbers from 1 to 1000,
and the second one containing the even ones.

HINT: Start with the file WriteData.java

TASK BREAKDOWN:
---------------

PREPARATION
* Copy WriteData.java from the ENGR 131 Code Repository
* Copy TextFileIO.java to the same directory
* Copy WriteData.java to a new program OddsEvens.java

STEP 1:
* Edit OddsEvens.java to save 1-1000 in the file all.txt
* Compile, Run, Debug.  Look at output.

STEP 2:
* Edit OddsEvens.java to save the odds to file odds.txt
* Compile, Run, Debug.  Look at output.

STEP 3:
* Edit OddsEvens.java to also save evens to file evens.txt
* Compile, Run, Debug.  Look at output.  We're done!
