An associative array is a very useful data structure for all kinds of application. An associative array is just a set of (key, value) pairs. Many programming languages, such as PHP and Perl (using hash variables) implement the functionality to work with these structures. Also Java incorporates associative arrays in the form of instances of the java .util.Hashtable class.
