Came across this class for permutating a set of values. When executed, it dumps the permutations to System.out. My question: is there a way to get each permuted value as a string or int instead/as well?

Much appreciated

Perm.java

I haven't looked at the linked code, but putting the data into an array should work.

Could you take a look at it? I'm not sure how exactly to go about it

[WingedPanther]

Having just looked at the code, are you aware of how many permutations of the string "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ" there are? While you could (in theory) produce all the permutations, to store them in memory will cause a memory overflow on any computer in existence.

This is just the code I based mine off of. The string I'm using is much shorter

[WingedPanther]

Just realize that, given a string of length n, the memory required to store it will be approximately n*(n!) bytes, more if using unicode strings.
