Can't fix error of Array Index Out of Bounds

Question

The code that the error is pointing to is:

letters[addr(tmp.charAt(0))] = Integer.parseInt(tmp.substring(2,tmp.length()))

And it is initialized in main:

int letters[] = new int[26]; //holds variables
for(int i = 0; i < 26; i++)
    {
    letters[i] = i+1;
    }

The error says that the string Index is out of bounds: -1. I am pretty sure that it is not the control that is doing this, as when i commented out control it did the same thing. I am trying to figure out how to fix this, and would appreciate any assistance.

Answer 1

just place an if condition before as follows

String tmp = scanner.next();

if(!tmp.length()<=1)
{
letters[addr(tmp.charAt(0))] = Integer.parseInt(tmp.substring(2,tmp.length()))\
}

else
{
    //do something to handle ArrayOutOfBondsException
}
