Hey Java Fan,
My apologies for the complicated code. As much as i'd like to simplify it, I have not been able to get the functionality i want.
As mentioned earlier, my goal is to just sort the hash for print purposes. I do not care what order it is otherwise. The data i have is a collection of methods of different categories stored in different files.
I wish to print them in ascending order of Category then ascending order of files that belong to that category followed by ascending order of Name of methods in each of those files. ie.

Functions
    Alpha.dat
       ...
       MNO
       ...
    ...
....
Methods
    Beta.dat
       ABC
       ...
    ...
...

As explained earlier, I can do it, but it takes too much time to do so and I wanted to know if i can speed it up.
I hope this explains what I wish to achieve.
