Accessing Array Elements, Java Array Tutorial

Accessing elements of an array

Individual elements of an array can be accessed by specifying index with [] operator, with the following syntax.

arrayName[<index>]

Here index can be any expression, which evaluates to non negative int value. Array index always starts at 0 and ends at arrayName.length – 1. Array index is automatically checked to ensure that it is well within the bounds. If index is less than 0 or grater than arrayName.length, an ArrayIndexOutOfBoundException is thrown.

Note: [] operator is not used when manipulating the array reference. For example, when array reference is passed to another method.
