Question

I’m trying to run my code and it says something about the exception:

java.lang.ArrayIndexOutOfBoundsException

I googled it, from what I understand it happens when I try to access an index that’s negative or greater than my array length.
But I can’t seem to find the problem, here’s my code: http://pastebin.com/sXsBbYfh

Thanks for any helpers.

EDIT: the error message:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 5
at Calculator.addOne(Calculator.java:127)
at Calculator.add(Calculator.java:88)
at Program.main(Program.java:8)

About the relevant part of the code, I have no idea, that’s why i’m coming to you.

Answer 1

The issue would appear to be with line 86

  arrResult = this.addOne(arrResult.length);

Array indexes are 0 based, so 0 – length-1 and you are passing length in and then using that to access your array on line 127

  switch(arrResult[arrayIndex])
