All,

I created a sample key generator which generates UUIDs (with lots of hex for the output like this):



The main app:



The output:



I need to figure out a way to take out the hex from this String and make it look a lot better.

Figured that I could probably do it inside a separate wrapper class (perhaps a Filter) which contains an arbitrary map for the hex letters (A=G,B=M,C=X,D=U, etc.).

That way, the key (or a substring of the key) would turn into: 4HD5-K8X3-42TL.

Would appreciate it if someone could help me with the separate wrapper class which contains the map converter...

Any reason why you don't just call the toUpperCase() method of String?
