The ArrayIndexOutfBoundsException comes when your code, mostly for loop tries to access an invalid index of the array. If you have worked in C, C++ then you will notice this difference between array in C and Java. You simply cannot access invalid array index in Java i.e. how to indexes which are less than zero and more than the length of the array. ArrayIndexOutOfBounds is also a subclass of IndexOutOfBoundsException which is used to throw error related to invalid index e.g. try to access outside of length in String etc. An array is a data structure which is the base for many advanced data structure e.g. list, hash table or a binary tree. The how to solve array stores elements in the contiguous memory location and it can also have multiple dimension e.g. a two-dimensional array. You can use the 2D array to represent matrix, a board in games like Tetris, Chess and other board games. A good knowledge of data structure and the algorithm is a must for any good programmer. You should read a good introductory book e.g. Introduction to Algorithms by Thomas Cormen to learn more about array in Java. Understanding ArrayIndexOutOfBoundsException This error comes when you are accessing or iterating over array directly or indirectly. Directly means you are dealing with array type e.g. String[] or main method, or an integer[] you have created in your program. Indirectly means via Collection classes which internally use an array e.g. ArrayList or HashMap. Now let's understand what information the associated error message gives us: java.lang.ArrayIndexOutOfBoundsException: 0 means you are trying to access index 0 which is invalid, which in turn means the array is empty. Here is a Java program which reproduces this error by accessing the first element of the empty array i.e. array with zero length: public class HelloWorldApp { public static void main(S
