OOP is a form of a design philosophy
that is the acronym to Object Oriented Programming and uses a different
programming language as compared to the classical procedural programming
languages. Further based on a concept of objects that at times may have data
present as fields OOP is also referred to as attributes and code (Kindler, 313).
The codes are in the form of procedures also referred to like the methods. The
object’s procedures are capable of accessing and even modify the data fields of
the subject matter they align towards. According to OOP, the computer programs
are made out of the objects that closely interact with one another. In as much
as there is diversity in the languages of OOP, the class-based ones are the
most accepted which means that the objects are instances of the particular
classes which in turn determine the type. Some of the major object-oriented
languages include the Swift, Python, C++, Ruby, Objective-C, Common Lisp,
Smalltalk, Java, C#, Delphi, Perl, and PHP (Michael,
470). The OOP is the successor of the Procedural programming that had
challenges with code reusability, unlike the OOP. With the procedural
programming, only the procedures could be reused to make them flexible and also
generic. Therefore, the OOP design has revolutionized the world of programming
over the course of time and is fundamentally capable and efficient than the
classical programming languages.
Advantages of OOP
The major benefits and also goals of OOP are:
make the complicated software faster to develop and also easy to maintain.
enables the reusability of codes easier through the application of simple and
also widely accepted and fundamental principles.
provides a clear modular structure for the program and hence is instrumental
and superior at defining the abstract data types where the execution
particulars may be concealed, and the unit may have a visibly defined
is essential for developing graphical user interface due to the excellent
framework for code libraries provided by the OOP allowing for the adaptation
and modification of software components ((Kindler,
For programming language to be object
oriented at any given instance there is a need to enable the working with
classes and objects coupled with the implementation of the fundamental
principles of OOP and the concepts. These may include the inheritance,
encapsulation, abstraction, and polymorphism.
Encapsulation enables the hiding of the
unnecessary details within the classes and also provides a very clear,
simplified interface to work with them. It can hide the data implementation
through the restriction of the access to the Accessors and the Mutators. The
accessor is the methodology used to ask the details of an object regarding
itself. They are found in the form of properties that have an accessor method
but not restricted to the properties meaning that they can be any method
offering information on the state of the object. The mutators, on the other
hand, are the public methods that may be used to modify the condition of the
object (Michael, 470).
Data Abstraction and encapsulation are
widely tied together, and it is the simplest principle to understand (Kindler, 315).
Abstraction is the development of classes, objects and the types of data in the
form of interfaces and also functionality as an alternative to their
implementation details. It is imperative at helping the programmer to deal with
the objects through consideration of their essential characteristics ignoring g
the other details.
Inheritance is the process by which the
objects are capable of acquiring the properties of the objects in another
class. It makes it possible for class hierarchies to improve the code
readability and also enable the reusability functions (Lewis and Loftus, 100).
The reusability provided by the inheritance in OOP may take the form of the
addition of features to an existing class without causing any modification and
achieved through the derivation of a new class from one that is existent, and
the new class contains the features of the both classes.
Polymorphism is essential at enabling
working in the same manner with the different objects defining a particular
implementation of abstract behavior (Lewis
and Loftus, 101). It is defined as the ability to take more than
one form in that the operation may exhibit diverse behaviors in the differing
instances. It is extensively used in the implementation of inheritance.
In conclusion, the OOP design has revolutionized the
world of programming over the course of time. It is fundamentally effective and
efficient than the classical Procedural programming languages that were
difficult to reuse. The OOP has made it possible for the reusability of codes
and also has made the work easier for the programmers. It has been so due to
the ability to work with classes and objects coupled with the implementation of
the fundamental principles of OOP and its concepts.
