I'm new to java and i'm trying to find a way of incrementing through an user input IP address range.
For example from 192.168.0.1 to 192.168.0.255. However the way my application works at the moment is the take the from and to ip addresses as a String.
Is there a way I can increment through all the ip addresses the user input from and to?
Hope this makes sense and please dont flame me, I have looked for an answer!

In java if I am looping over the keySet() of a HashMap, how do I (inside the loop), get the numerical index of that key?
Basically, as I loop through the map, I want to be able to get 0,1,2...I figure this would be cleaner than declaring an int and incrementing with each iteration.
Thanks.

Today I was browsing through some question on this site and I found mention of enum being used in singleton pattern and that there are some thread safety benefits to such solution.
I never used enums and I have been programing in java for more than couple a years now. And apparently they changed a lot and now they even do full blown support of OOP within them selfs.
Now why and what for should I used enum in day to day programing?
Given a list of potential class names:
1. Alaska
.
.
.
50. Wyoming
Is there a tool that will create empty java class files for each with supplied parameters?

I have read this question and I'm still not sure whether it is possible to keep pointers to methods in an array in Java, if anyone knows if this is possible or not it would be a real help. I'm trying to find an elegant solution of keeping a list of Strings and associated functions without writing a mess of hundreds of 'if's.
Cheers
edit-
'functions' changed to 'methods', seems to bug people.
