hey again i've fixed my code a little and need a little help. I've got the flush and one pair determinations to work but the three of a kind, straight, straight flush and royal straight flush are giving me a little trouble. If anyone has any suggestions, i would really appreciate the help my code is below
By the way, for the straight determination, i could only get rank numbers that are close to each other, like 2, 3, 4 to make Straight output. Numbers like 2,15,4 which = 2,3,4 when it outputs doesnt output straight

1. Are you sure, that your example is correct 2,15,4 which = 2,3,4 ... and not 16 = 3?
2. You don't check the case, when you get, for example 4,2,3. In that case your (x == 2) and (ex == 1), but it is still Straight.
P.S. If the first part of your problem (I mean thread "determine type of card hand") is solved, mark it solved, please

hii bro
your codes work properly but you are missing braces at the end of the method.
good luck
