Object-Oriented Programming and Java


Object-Oriented Programming is a paradigm based on the concept of taking real world objects and representing them in coding. OOP is used widely among various programming languages. The concept of this programming style uses classes and objects. These objects can be broken down using various attributes like functions – methods or attributes – properties. OOP consists of abstraction, encapsulation, inheritance, and polymorphism.  Combined these make up the four pillars of object-oriented programming.


Abstraction: Only showing the user the necessary details for accessing an object

Encapsulation: Restricts the access of properties or methods of an object, by hiding data

Inheritance: Allows the reusability of code of an existing class

Polymorphism: Helps the user determine what function to run while it is running

Here are some examples of Object – Oriented Programming languages that have the concept of classes:

·      C++

·      Java

·      JavaScript

·     Python

    As a beginner to computer programming, I recommend beginning with Java.  It is a great way to begin learning how to build application using programming language. Java is an OOP that is both a high-level language and is easy to read and understand. The most popular use for this programming language is GUI, gaming web and mobile applications.

    Java was created by James Gosling at Sun Microsystems, Inc. and launched in 1995. The simplicity of Java allows the programming language to be written the same way on a variety of platforms. For this reason, James’s motto was Write Once, Run Anywhere” (Britannica, 2021).

    There are several tutorials and job aid available to help a beginner like yourself get started with Java. On Oracle there are tutorials that cover the basics such as installing the Java Software, basic input/output and essential concepts. Once you have installed Java a great exercise to get your feet wet would be the “Hello World” activity.  This is a great way to begin exploring the World of possibilities with coding.

  An algorithm is a set of rules or instructions that calculates operations and functions for computers to solve problems. Data structures are also, known as abstract data types that organize and store data in a format that enables it to be access and modified in an efficient way. Throughout this article I will share with you multiple types of algorithms and data structure designs. All of which have both their pros and their cons.   In addition, I will outline how to use these techniques to develop a structured program. Let’s get started. When determining the most appropriate algorithm to use in developing a structured program you should consider the time complexity. The time complexity is the relationship between the growth of an input size and the growth of the operations executed. The Big O Notation will classify the algorithm based on run time and space requirements. Examples of Algorithms: Binary Search: The binary search is an algorithm that finds a value within a...

The major functions of an Operating System (OS) are process management, memory management,  storage management, input/output (I/O) control and management, and protection and security.  Process   management executes instructions sequentially until complete. This function relies on the  CPU,   memory I/O and files to carry out its assignment. Additionally, it allows for creating system  process  and  provides the mechanisms for synchronization and communication. All data passes through memory management before and after it is processed. The same holds true for instructions for them to execute. This function manages which portion of the memory is utilized and how by allocation and deallocation. The storage management provides a uniform way for storing data that passes through the OS. This function also converts physical storage into local storage, like files. The management of files consist of creating, deleting, and mapping. I/O subs...
