Title: duplicates in an array/hash[SOLVED]
Post by: Splankton on June 05, 2014, 02:13:19 PM

Hi
I have a simple hash table that iterates a few times to get a random name from an arraylist, and add that into a hash table as the key(string) and it's index(int).
It all works fine except i sometimes get 2 duplicate indexes.
So it looks a bit like this
Mike 6
Dave 3
Rob 2
Joe 5 *
Steve 0
Chris 5 *

By the way, I never get name duplicates.
I made a temp arraylist that copies from the source array, so I can get a random name, then remove it from the array, leaving the source array free from any removing.
So I don't get why I sometimes get duplicates?
Can someone help?

hi,

 it's almost definitly in your logic that you call twice the same set of logic that leads to a duplicate.

double check your logic accuratly and use the debug flow to go trhough all the steps one by one.

 Bye,

Hi, thanks Jean.  You're right, the index from the target array was removing the picked item, so say index 3 was removed, so the item at index 4, becomes index 3 etc.  Silly error, but I have it working now.
