History Of OOP
The history of object-oriented programming, commonly referred to as OOP, started off with two languages. Simula 1 and Simula 67. Simula 67 brought about the key concepts of object-oriented programming. Ole-Johan Dahl and Kristen Nygaard developed the Simula languages in the middle of the 1960?s. The Nygaards work in operational research created a need for precise tools for the description and simulation of complex man-machine systems. The idea was created for developing a language that could be used for system description (for people) and system prescription (as a computer program through a compiler).
There are several object-oriented languages. The three most common ones are, Smalltalk, Java, and C++.
Smalltalk was developed in the 1970?s. Alan Kay created it at the Xerox Corporation Palo Alto Research Center. Although it never achieved the commercial success of other languages, ?Smalltalk is considered by many to be the only true object-oriented programming environment, and the one against which all others must be compared? (?Smalltalk?).
Java, developed by Sun Microsystems, was originally called OAK. It was designed to be used in hand held devices and set-top boxes (i.e. Web TV). In 1995, OAK had not seen the success that
