Ordering Rows of text file

The two text files ,input file and template are read from the disk , Hash Maps / Array Lists are being extensively used to check and arrange for the order and written in an output file.Basic Advantage is without altering the code and by changing the template file, display order can be altered in the output file.This has been successfully implemented in our project and could be useful wherever text file needs to be ordered based on particular order.
