Array

An array object (or simply array) contains a collection of elements of the same type, each of which is indexed (i.e., identified) by a number. A variable of type array contains a reference to an array object.

To use an array in Java we have to:

1. declare a variable of type array that allows us to refer to an array object;
2. construct the array object specifying its dimension (number of elements of the array object);
3. access the elements of the array object through the array variable in order to assign or obtain their values (as if they were single variables).
