Newbie to Newbie: An Introduction to Java Installation

Welcome fellow programmers and future programmers! For this post we are going to cover the basics of Java installation and what Integrated development environment (IDE) tools to use with your Java code. We will also delve into the concepts and features of the object-oriented design principles.

Java is a versatile and widely used programming language that forms the backbone of numerous software applications. Whether you are a seasoned developer or just starting, Installing Java is a fundamental step in your journey. Firstly, you will want to visit the official Oracle Java Developer kit (JDK) download page found here: https://www.oracle.com/java/technologies/downloads/ and select the version that is compatible with your Operating System (OS). For me, I am on a windows device so I selected the Windows tab and then found the most recent JDK version to download.

Once installed you will need an IDE tool in order to create and run/test your programming code. For me I used NetBeans IDE but you can use others such as Notepad+, Notepad, WordPad, Visual Studio (more common with Python), IntelliJ, and even eclipse. I followed this video for NetBeans on Youtube on the setup and creation of my first “Hello My Name is” Program. You can find the tutorial here: https://www.youtube.com/watch?v=wdpxnKry0ic

Object-oriented design (OOD) principles are the bedrock of effective software development. Some key principles include encapsulation, abstraction, inheritance, and polymorphism (Paul, 2019). Understanding these principles will help to understand and navigate the world of programming through Java. 

  • Encapsulation involves bundling data and methods into a class, hiding internal details and exposing only what’s necessary. This promotes modularity and enhances code readability. 
  • Abstraction simplifies complex systems by modeling classes based on their essential features. Developers focus on relevant details, ignoring unnecessary complexities, leading to more manageable code.
  • Inheritance enables a class to inherit properties and behaviors from another class. This promotes code reuse, allowing developers to build on existing code and create a hierarchical class structure. 
  • Polymorphism allows objects of different types to be treated as objects of a common type. It can be achieved through method overloading (compile-time polymorphism) and method overriding (runtime polymorphism), enhancing flexibility in code design. 

Overall the installation of Java can be easy, but sometimes overwhelming. While I know a thing or two about programming, I am just as new to the Java world. I found browsing Oracle: Java Documentation https://docs.oracle.com/javase/tutorial/ helpful to see what tutorials are out there to help me on my journey into downloading and understanding Java.

Newbie to Newbie: Algorithmic Design and Data Structure Techniques

Image
"It's so easy even a dinosaur can do it!" Are you new to the programming world and feeling overwhelmed by the terms "algorithmic design" and "data structures"? Fear not! In this blog post, we'll embark on a journey to demystify these concepts and explore their crucial role in developing structured programs. Algorithms are step-by-step procedures or instructions for solving a problem. Algorithmic design involves devising efficient algorithms to tackle various computational tasks. Data structures are formats for organizing, storing, and managing data. They provide efficient ways to access and manipulate data. Think of algorithms and data structures as the building blocks of programming. Just as a builder carefully selects the right bricks and mortar for constructing a sturdy building, a programmer chooses appropriate algorithms and data structures to craft efficient and reliable software. Certain algorithms and data structures are better suited for s...

Database Management: A Fundamental Component of Information Technology

Image
Database Management is a fundamental component of information technology, it is closely interwoven with the principles and history of computing, major hardware components, programming languages, application software, database concepts, and network architecture and security  (Vahid & Lysecky, 2019).  Database Management is a critical aspect of information technology that involves organizing, managing, and retrieving structured data efficiently. It connects to the core concepts of data storage, retrieval, and manipulation, which are fundamental in the realm of IT and computer science. The evolution of database management is closely tied to the history of computers. The means by which computers operate, including storage devices, processors, and memory, directly influence database performance and efficiency (Sumathi & Esakkirajan, 2010). Initially, data was stored in simple file systems, but with the growth of computing power, relational database management systems (RDBM...

Outside of the Classroom: Computers in the Workplace

In the healthcare industry, computers are crucial, ranging from patient care and record-keeping to research and development. Here's an overview of the functions of computers in healthcare and the importance of computer literacy for employees in this industry. Computers are used to create, maintain, and access electronic health records. EHRs like Epic, Cerner, and Meditech store patient information. To include medical history, diagnoses, medications, treatment plans, immunization dates, allergies, radiology images, and laboratory test results. Computers aid healthcare professionals in making informed decisions by providing evidence-based recommendations. These systems can analyze patient data to offer guidance on diagnosis, treatment plans, and medication dosages. Computers facilitate remote consultations, diagnostics, and monitoring of patients through telemedicine applications. This is particularly important for reaching patients in remote or underserved areas. Computers are utili...
