Declaration of array variables

To use an array we first have to declare a variable that refers to the array.

Declaration of array variables

Syntax:

type[] arrayName;

where

• type is the type of the elements of the array to which the variable we are declaring will refer
• arrayName is the name of the array variable we are declaring

Semantics:

Declares a variable arrayName that can refer to an array object with elements of type type.

Example:

int[] a;     // a is a variable of type reference to an array of integers

Note that, by declaring a variable of type reference to an array we have not yet constructed the array object to which the variable refers, and hence the array cannot be used yet.
