Thread: java.lang.ArrayIndexOutOfBoundsException

Hi, I posted a question on here a couple of days ago and somebody came back with a reply realllly quickly, I can only hope that it will be the same in this case, heres my code in its entirity (I've moved it all together/commented so that its more readible).

As far as I can tell there are no obvious syntax problems but perhaps I am approaching this all wrong? I'm receiving the error from my compiler stating:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 42
at callhelper.NewMain.main(NewMain.java:92)
Java Result: 1

But what gives?, line 92 is around the area where my first array call is used "prefixes[i]" for the while loop,

                if (string.equals(prefixes[i])) {

                i++;
          }
        }
    }
}

Sorry, I probably didn't need to dump the whole code in here but I thought that it may help for completeness Any hints/(constructive)criticisms or words of wisdom would be greatly appreciated

I'm certain the problem is here :
if (found != true) { //if the items not found then grab the list of prefixes for the south east
String[] prefixes = SEAST.getPostcodePrefixes();
while (prefixes[i] != null) { //then loop through all of the prefixes until the whole of prefixes[] is looped or
if (prefixes[i].equals(string)) { //if a prefix in the array is equal to the string, do something and set found to true.
System.out.println("found in southeast");
found = true;
}
i++; //increment the loop control for next iteration,
}

Kind Regards,

I'm glad you solved this anmaston
