IndexOutOfBoundsException :Thrown to indicate that an index of some sort (such as to an array, to a string, or to a vector) is out of range.

ArrayIndexOutOfBoundsException, StringIndexOutOfBoundsException are two classes, which have implemented IndexOutOfBoundsException.

ArrayIndexOutOfBoundsException: Thrown to indicate that an array has been accessed with an illegal index. The index is either negative or greater than or equal to the size of the array.

StringIndexOutOfBoundsException:Thrown by String methods to indicate that an index is either negative or greater than the size of the string. For some methods such as the charAt method, this exception also is thrown when the index is equal to the size of the string.
