nice code but not really correct. This gives an output of [H, o, w, , c, a, n, , m, i, r, r, o, r, s, , b, e, , r, e, a, l, , i, f, , o, u, r, , e, y, e, s, , a, r, e, n, ', t, , r, e, a, l]

it may be a bit redundant to make the Human class abstract here, since there are no methods or attributes inherrited by man or woman, so theres no common behavior to impliment

Is it possible to test the code on Eclipse?, I'm new to programming, and I can't run the code.

Best practice !!!

Absolutely genius...I never thought it.

Give this man a medal ?

genius

ahahahahaha))))

This proves that happiness is a state of mind and not a measure of intellect :D

I think I just died a little bit inside seing all of these "magic numbers" :)

bad, bad boy

It isn't written in instruction that test strings will not start with whitespace characters or that there will be always only one whitespace character between words. They're special cases which you didn't take into consideration.
