What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it?

Question

I want to know what causes the exception and what can I do to prevent it from happening.

Answer 1

An ArrayIndexOutOfBoundsException occurs when you try to access or do operations on indices that are negative or greater than or equal to the size of the array. To prevent it you have to avoid using negative values in the index and do operations only on the indices that are less than the size of the array.
