Thanks ! I was trying to find a way around loops but was just missing a couple of things ;)

I was working with integers rather than characters but I was wondering why did you use Scanner ?

First i wanted to say A = 'A', B = 'B' and so on, but when i printed the variables of screen in this format I thought it will be hard to read. You can work the same with integers, just change the type and assigment of A, B, C, D and aux; I used scanner because i wanted to manually give the number of times i want to permute. I give the number from keyboard, store it in number variable and use the variable in the for loop.

AH alright I actually gave each variable an integer A=1 B=2... and tried to mathematically permute them by add 3 to A, 1 to B, -1 to C and 1 to D but didnt work

It did not work because that is not what "permute" means.
