  object-oriented programming
  object-oriented language
  object-oriented programming language
      (OOP) The use of a class of programming
     languages and techniques based on the concept of an "{object"
     which is a data structure ({abstract data type) encapsulated
     with a set of routines, called "{methods", which operate on
     the data.  Operations on the data can __only__ be performed via
     these methods, which are common to all objects that are
     instances of a particular "{class".  Thus the interface to
     objects is well defined, and allows the code implementing the
     methods to be changed so long as the interface remains the
     Each class is a separate module and has a position in a
     "{class hierarchy".  Methods or code in one class can be
     passed down the hierarchy to a subclass or inherited from a
     superclass.++This+is+called+"{inheritance">superclass.  This is called "{inheritance".
     A procedure call is described as invoking a method on an
     object (which effectively becomes the procedure's first
     argument), and may optionally include other arguments.  The
     method name is looked up in the object's class to find out how
     to perform that operation on the given object.  If the method
     is not defined for the object's class, it is looked for in its
     superclass and so on up the class hierarchy until it is found
     or there is no higher superclass.
     OOP started with SIMULA-67 around 1970 and became
     all-pervasive with the advent of C++, and later Java.
     Another popular object-oriented programming language (OOPL) is
     Smalltalk, a seminal example from Xerox's Palo Alto
     Research Center (PARC).  Others include Ada, Object
     Pascal, Objective C, DRAGOON, BETA, Emerald, POOL,
     Eiffel, Self, Oblog, ESP, LOOPS, POLKA, and
     Python.  Other languages, such as Perl and VB, permit,
     but do not enforce OOP.
