for loop is for the integer "i", but where did you use it?
I don't. It is used to keep track of the iterations (see the i<5 in the for loop declaration), if you don't do this it will loop forever.
i is incremented each iteration, then when i fails the check of i<5, i.e when i equals 5 (or more) the for loop terminates.
You could also do:
//loop code here
Remember 5 is just an arbitrary number, i used 1/2 the array size as the number of shuffles, but the more you do the more it shuffles.
