java.lang.ArrayIndexOutOfBoundsException

java.lang.ArrayIndexOutOfBoundsException is a runtime exception that occurs when an array is accessed with an invalid index. This means that the index being used to access an element in the array is either negative or greater than or equal to the size of the array.

For example, if an array has 5 elements, the valid indexes are 0, 1, 2, 3, and 4. If you try to access the element at index 5, you will get an ArrayIndexOutOfBoundsException.

This exception is thrown when an array is accessed in a way that is not allowed by the Java programming language, such as trying to access an element that does not exist or trying to access an element outside the bounds of the array.

To avoid this exception, you should always make sure that the index being used to access an array is within the bounds of the array. You can do this by using a loop or a conditional statement to check the index before accessing the array.
