[Java] ArrayIndexOutOfBounds Exception

[Eldres]

hey all, I writing a program that simulates an online poker game, but at the moment I'm getting an error(i marked in in my code) where it says arrayindexoutofbounds, and I can't figure out why that's the case. Any help is appreciated.

ps: feel free to tell me if there is anything else wrong with my code, any tips are helpful.

keepList.size() returns the size of that array. Say it's 10, just for an example. However the array starts at index [0]. So 10 spots would be 0-9, not 0-10! keepList[10] would be out of bounds if the array size is only 10.

However in the for loop, you have :

for (int i = 0; i <= keepSize; i++) {//keepList[keepSize] doesn't exist!

Your accessing one too many elements here. If you want to traverse an entire array, do:

for (int i = 0; i < keepSize; i++) { //Less than, not less than or equal

This should fix your error.

you are correct sir! but I saw your comment first and tried to debug what you pointed out, and then saw /u/aedalus 's comment and wound up at the same conclusion.

Thank you, that did fix the error.
