The Concept Of Abstract Data Types

In this presentation I will be looking at data types and how they can be used and represented.

This paper will discuss the difference between procedural modules and object-oriented methods. How both methods work and some of the pro

P4- Outline the benefits of having a variety of data types available to the programmer

Data Types: We can use many data types like Boolean, char, byte, int, short, float, long, double.

Chapter five is titled “Abstracting” which is a mystery that cannot be perceived to be general or generally understood. The first main point states that abstraction is “incredible simple that it is difficult to perceive its structure.” In other words, abstraction does not present the whole, but an essence in the form of a property that then reveals the whole. For example, a stick figure is related to a human figure, even though it is simple lines that represent the body and a circle representing the head. Another main point indicates that one must ‘know what abstraction is… why it is important… and learn how to find the simple concepts hiding among complex expression.” Most importantly, it is revealed by going beyond the senses into the eye of the mind, providing purity. In order to find abstract one must know it evolved from reality; all the traces from reality were removed, and was reduced to an essential form. The third main point, suggest abstractions in different careers influence each other such as, artistic abstractions lead to scientific and technological benefits. Demonstrated through the invention of taking motion pictures of a horse in the air as an art; leading scientist developing the method to analyzing key bones and limbs. Therefore, abstraction is a never-ending quest for the greatest simplicity and more arcane truths.

Programming languages are vast and diverse in their numbers. These different languages use fundamental styles of programming called programming paradigms. These programming paradigms layout the particular design approach that a program will use to solve a problem or achieve an objective. Of the many different types of programming paradigms, some of the more distinguished ones are procedural, functional, logical, and object orientated programming. Recently the object orientated languages have been rising in popularity due to their ability to easily implement large programs. There are many different object orientated programming languages (OOPLs), among them are C#, Java, Ruby, and Python. This essay will compare and contrast two of these languages: Python and Java.

The table below characterises the four main programming paradigms by their descriptions and scenarios in which they are suited to.

The need for more powerful and user-friendly software grows exponentially every year. This means that there is a higher demand for better quality and more versatile software. Higher quality software that is versatile and consistent was very difficult to create for developers before object-oriented programming was created. The object-oriented programming method of utilizing objects and methods has revolutionized the way programmers create new applications. By allowing objects to be reusable and flexible, this allows more time to be spent on creating meaningful coding tasks with less time coding GUI’s (Gaddis & Irvine, 2014, p. xvii). Microsoft’s Visual Basic and Oracle’s Java are object-oriented programming languages that are very powerful applications which contain many similarities while having small differences in the syntax and the usage of elements that are common to both.

The modern programming is based on the concept that “program little and use more”. The object oriented programming languages are playing a vital role in the industry of development. The OOP introduced following concepts:

A procedural programming a program that contains a series of computational steps to be carried out. Procedural programming is a term to denote the way in which a computer programmer writes a program. This program works by using sequences of instructions. The types of procedural programming are pascal, c++ and c.

The purpose of the programming languages as Coded language to write information by programmers that a computer could understand to do what the programmer wants. A computer language is used binary ( '1 ' and '0 ') code as call the machine language that a computer can execute instructions quickly without any translator or interpreter program, but is complicated. The high level languages such as C++ and java are very simpler for use, but it need to another program to transfer a high-level code into a computer language, for this are slower. There are many of programming languages are being always developed.

In this programming language we have to understand the meaning of various terms such as objects, class, data abstraction and encapsulation, inheritance (one of the most powerful concept), polymorphism, data binding, and message passing etc.

Object-Oriented Programming is a programming paradigm emphasized on “objects” which consists of data attributes and methods (Lewis; Loftus). Data attributes are comparable to nouns while methods are comparable to verbs in English. For instance, a person represented by object, has name, age, and gender as its data attributes. The person will be able to think, speak, and write with the representation of methods in the object.

Object-oriented approach was developed in late 1950’s in MIT to overcome the drawbacks of procedural- oriented approach. Ii is commonly known as OOPS. Now, it has become most preferred programming approach by software engineers to solve real world complex problems. The traditional procedural languages solve problems in terms of the structure of the computer i.e. memory bits and bytes, array, decision, loop rather than thinking in terms of the problem which is to be solved.

Local data structures: It verifies that during program execution integrity of data is executing properly.
