I am a informatica developer, I know SqL, Pl/sql etc but very new to Java.
Just know the basics(may be less) of Java. I am assigned a this project.
God only know knows why..I have a simple code to merge the files and
watermark them,watermark code is a separate class. If you see I am passing
the file as input parameter. But I am not sure how to sort based on
arguments. The date would be created Date on the image file that I am
merging. Trust me this is not a homework :)..
