What is ArrayIndexOutOfBounds exception?

Answer 1

Just Google for it.. It means your array index is out of bounds. That means that you try to access a position that doesn't exist in your array.

Answer 2

If you have an array of length (n), assignment of an element to an index >=n will resul in that

Answer 3

ArrayIndexOutOfBoumdsException is an exception which occurs when you make an attempt to access an array element beyond the index of that array.

Answer 4

An ArrayIndexOutOfBounds means that a call to an index that doesn't exist has been made.

For instance, when creating an Array int num [25] you have 25 ELEMENTS, which is the length of the array. An Index will ALWAYS be -1.length because, the index starts at 0 and ends at 24. It ends at 24 because it must kept within the BOUNDARIES of the element and not over.

So, when you have an ArrayIndexOutOfBoundsException, it means that if you make a call say for, Index [25] or index [26] and it doesn't exist, then you get a thrown exception error. Elements is the length of the array. The index is the boundary of the array.

This can also occur if an index has been skipped or too many calls have been made to the same index.

If you want, you can create a method that checks for the element length.

String[] exampleArray = { "Goo", "Moo", "Joo" };
int arrayLength = exampleArray.length; //Important
System.out.println("The length of the array is: " + arrayLength);

This will print out the total element. Subtract -1 for your index.

OR

boolean inBounds = (index >= 0) && (index < array.length);

Answer 5

as the name implies its an exception thrown if a program catches the array index when its out of boundary...

Answer 6

array length is 7 but you give the input 8 values continuously that's a array index out of bounds exception

Answer 7

This exception arrives when an element in array has index greater tha the maximum index of array.e.g.
int arr[10];
arr[13]=10; //exception here max index of array is 9

Answer 8

if we have array of n index then
element has index >=n is called ArrayindexoutofBounds

Answer 9

you trie to enter the position of array thatq mightw not be in your array , more no of input in array then actual size
