JAVA INSTALLATION AND OBJECT-ORIENTED PROGRAMMING PRINCIPLES

-

Java is an object-oriented programming language. It was developed with the idea that “write once run anywhere”. Java can be installed using the following tutorials

Features of Object-Oriented Programming

Object oriented programming model makes use of the concept of classes and objects. The software programs that use this model arrange the entire program around data and objects unlike other programming paradigm’s where the program is arranged according to functions and logic. (See Alexander s Gillis, Sarah Lewis,2019)

This approach follows the following concepts for software development (see Java oops Concepts,2021) 

       Object – Object refers to a real-world entity such as a student, customer, flight, car etc. These real-world entities will have a state and a behavior. Every object has a address associated to it and they communicate with each other. Example – customer is an object which has a name (state) and is a regular customer to a e commerce website(behavior).

       Class – collection of objects is referred to as a class. Classes can also be defined as blueprint for individual objects, attributes and methods. (See Alexander s Gillis, Sarah Lewis,2019)

      Inheritance – Inheritance is defined as a process where classes inherit the features of existing classes (see interview bit, 2021).

      Polymorphism – Polymorphism is defined as the ability of an object to many forms. (See Alexander s Gillis, Sarah Lewis,2019)

      Abstraction – Abstraction refers to hiding the details and displaying the functionality. Example a car from outside is a single unit however inside there are multiple parts installed in it. see Java oops Concepts,2021)

      Encapsulation – Encapsulation is defined as wrapping of code and data together in a single unit called class.

Web/Mobile App Critique

  The application I chose for this weeks discussion was the   YouTube Web App. Usability Once a user loads the web app, he/she quickly notices a search box with a search button where one can search videos they want to watch. The search tool makes it easier and simple for a user to find a video of their choice without going through all the videos uploaded in the website's database. Additionally, it provides a microphone, an alternative to the search box, which can be very useful for physically challenged persons.  Besides, it has a user-friendly menu where users can click and view trending videos, browse the history of watched videos, liked videos, and your videos. The app allows users to create a list of videos to be watched later.    The app also provides a platform where users can create personal accounts using their email addresses to subscribe to videos they like and get notified whenever new videos are uploaded. This reduces the time and complexity, and saves data bundles for

Traveling Through a Network

     A packet is simply a piece of information traveling through a network. To begin with a packet arrives at the router which is responsible in determining the IP address of the packet, the IP address usually centers back to the original device used having been placed by the IP protocol. When the router has determined the packet’s IP address then it is sent to that address. If the IP address is not found then the packet is sent to a backup router where hopefully its destination is determined if not then it is passed to another router until the destination’s IP is found.      A ping can be explained as a signal sent to a site that requires response. The ping sent to google.com brought positive feedback as shown in the diagram 1 below, it shows the ping reached its destination and feedback has been sent back. The trace route to amazon.jp is shown in diagram 2 whereby we see the ping having trouble reaching its destination hence the timed out error at the end. Finally the trace route sho

     The fundamentals of information technology prepare students to succeed in their workplaces and future careers. Students usually begin their careers by establishing awareness of the role essentials to professional communications skill and leadership and their essentials for an organization's success. Information technology careers relate to the fundamentals of information technology through development. The fundamental of information technology is a discipline that trains students and trainees on building the skills professionally and ethically and use them for the organization's success. Various IT careers develop information technology fundamentals—learners, for instance, gain presentation management software skills, email, and word processing knowledge. A computer operates through capturing information, processing it, and giving outputs. Information technology fundamentals enable students to demonstrate digital literacy through the introductory study of operating systems
