Java Collections Framework API

Introduction

The Java collections framework (JCF) refers to a set of interfaces and classes that execute frequently reusable collection data structures (Flanagan, 2005). Unlike is name, a JCF functions similar to a library. It offers both interfaces that illustrate various collections as well as the classes that implement them. Simply defined, the JCF is a set of interfaces and classes which assist in efficient data storing and processing (Collins, 2011).

History

Collection execution in pre-JDK 1.2 Java platform versions entailed few data structure classes, except without a collections framework. The standard techniques of Java objects clustering were through the vector, the array and the hashtable classes, which regrettably were difficult to extend and failed to deploy a standard member interface (Becker, 1998). Thus, to solve the necessitate for reusable collection data structures, a number of independent frameworks were developed (IBM n.d.), Doug Lea’s Collection Package a long with ObjectSpace Generic Collection Library – JGL being the mainly used (Vanhelsuwe`, 1997). Primarily, the collections framework was designed then developed by Joshua Bolch prior to being introduced to JDK version 1.2. the collections framework reused various ideas along with Doug Lea’s collection package classes, which as a result, was denounced (Lea, 1999). Given that the JGL’s ideas we consistent with C++, which was not Sun’s objective, he opted for a compact framework. Later works included Doug Lea’s concurrency package made up of new Collection-related classes.
