TOPIK 1 INTRODUCTION TO OOP

method of programming based on a hierarchy of classes, together with well defined and cooperating objects.

languages used in OOP

Java, C++, C#, Phython

PHP, JavaScript, Ruby, Perl

Object-C, Dart, Swift, Scala

programming model which is derived from structured programming, based upon the concept of calling procedure.

languages used in prosedural programming

FORTRAN, ALGOL, COBOL

BASIC, Pascal and C

process of defining the problem in terms of real world objects with which the system must interact.

primary tasks in OOA

identifying objects

organizing the objects

defining the object attributes

defining the function of the objects

describing how the objects interact

process of defining the components, interfaces, objects, classes, attributes and operations that will satisfy the requirements.

implementation detail generally include

restructuring the class data

implementation of method

implementation of controls

implementation of associatations

technical approach used in analysis and design of an application / system

applied throughout the development life cycle to foster better product quality and even encouraging stakeholder participation and communication.

advantages

easy to understand

easy to maintain

provide re-usability

reduce the development time and cost

disadvantages

all time it is not easy to determine all the necessary classes and object required for a system

without an explicit reuse procedure this methodology do not lead to successful reuse on a large scale
