Diploma In IT Syllabus - Object Orientated Programming

The most widely used modern programming languages C++, Java and VB.Net all embrace an object oriented approach. It is now embedded in such diverse areas such as engineering, software architecture, analysis, design, programming, testing, deployment and maintenance. This module examines the application of the object oriented paradigm to programming. Candidates should have practical experience of at least one object oriented programming language.


  • To develop an understanding of the principles underpinning object oriented programming
  • To apply object-based approaches

Prior Knowledge Expected

    Candidates are expected to be familiar with the material covered in the Certificate syllabuses, particularly Software Development. Candidates should have practical experience of at least one object oriented programming language.

      What You Will Be Studying


      Genealogy of object oriented languages: structured programming, procedural programming, abstract data types, encapsulation, typed and untyped languages, coupling and cohesion.


      Encapsulation. Classes and objects. Class members: Data members (fields) and member functions (methods). Class member visibility (private, public, protected). Class hierarchies. Single and multiple inheritances. Inter-class relationships. Class variables and instance variables. Class methods and instance methods. Service methods and support methods. Scope.

      Constructors and destructors. Object initialization. Memory management. Garbage collection. Methods and messages. Method signatures. Method and operator overloading. Method overriding. Abstract classes. Dynamic (late) binding. Polymorphism. Software reuse. Subclasses (derived classes). Super classes (base classes). Invocation of super class methods and constructors.

      Objects vs. variables. Classes vs. types. Delegation. Collection classes. Class libraries.


      Unified Modelling Language (UML). Use case diagrams: actors, system boundary, <<uses>> and <<extends>>. Scenarios. Class diagrams: associations, aggregation, dependency, and inheritance. Object interaction diagrams, object state transition diagrams. Object constraint language (OCL): invariants, preconditions, post conditions.

      Design patterns. Pattern documentation: motivation, prerequisites, structure, participants and consequences. Examples of patterns: Adapter, Decorator, Iterator, Observer, Singleton.

      Books To Refer
