How do I fix java Lang ArrayIndexOutOfBoundsException?

Here are few handy tips to avoid ArrayIndexOutOfBoundsException in Java:

1. Always remember that the array is a zero-based index, the first element is at the 0th index and the last element is at length – 1 index.
2. Pay special attention to the start and end conditions of the loop.
3. Beware of one-off errors like above.

How do I prevent IndexOutOfBoundsException?

Use Proper Start And End Indices Arrays always start with index 0 and not 1. Similarly, the last element in the array can be accessed using the index ‘arraylength-1’ and not ‘arraylength’. Programmers should be careful while using the array limits and thus avoid ArrayIndexOutOfBoundsException.
