<strong>Arrays</strong> • <strong>Arrays</strong> can be used to create a collection of data values. – An array is a collection with a finite number of elements. – Elements in an array can be one of the following: •either values of a particular primitive data type, •or references to objects. – All elements in an array have the same element type. – An array has a length which corresponds to the number of elements in it, and cannot be changed after the array is created. • In Java arrays are objects. – Java provides language construction for declaration, creation, initialization and use of arrays. 6-3/20
