1.9 Changing the Size of Our StaticWordLibrary

Juppies 2 by Dr Heinz M. Kabutz

We change the number of words in our game by returning a smaller number in the getSize() method. Instead of WORD_LIST.length, we simply return 5. We now see only the first 5 words in our array, looping back to the first word once we reach the end.

If we make getSize() return 50, then we get a problem once we get past the end of the array. Fortunately Java behaves safely and just causes an ArrayIndexOutOfBoundsException. In other languages this can cause bad issues as we can then access memory that we should not see. I will talk more about this in the next section.
