ARRAYS

?A Java array is an Object that holds

an ordered collection of elements.

? Components of an array can be primitive

types or may reference objects, including

other arrays.

? Arrays can be declared, allocated, and / or

initialized all in one compact statement.

int[] ai;

int[] ia = new int[3];

char ac[] = {’n’, ’o’, ’t’};

The length of an array is fixed at creation

and cannot be changed, but a new, longer

array instance can be assigned to the Object.
