What Is Object-Oriented Programming in Java and Why Does It Matter?

Java is super popular in the programming world, and one of the main reasons for that is its use of object-oriented programming (OOP). So, what exactly is OOP in Java, and why should you care? OOP is a way to organize your code by grouping related data and functions into objects. This makes Java easier to work with, more organized, and simpler to update.

Key Ideas Behind Object-Oriented Programming

To get a grip on OOP in Java, you need to know four main ideas: Encapsulation, Inheritance, Polymorphism, and Abstraction. These concepts help you write clean and reusable code, which is pretty important in software development today.

Encapsulation: Keeping Data Safe

Encapsulation means protecting the internal data of an object from being accessed directly. You do this using private variables and public methods. When you take a Java course in Coimbatore, you’ll learn how this helps keep your code secure and safeguards data from accidental changes.

Inheritance: Building on Existing Code

Inheritance lets a new class take on the properties of an existing class, which cuts down on code repetition and encourages reuse. Grasping this idea is key if you want to dive deeper into Java development, especially in a Java Full Stack Developer course in Coimbatore.

Polymorphism: Flexibility in Code

Polymorphism allows you to treat objects as if they are from their parent class rather than their specific class. This means you can write more flexible code that works across different cases. You’ll definitely encounter this in Java training in Coimbatore, and it’s essential for creating scalable applications.

Abstraction: Simplifying Complexity

Abstraction is all about hiding the messy details and only showing what’s necessary. For example, when you use your smartphone, you don’t need to understand how everything works inside it. Java uses abstract classes and interfaces to make things simpler, which you’ll notice in any solid Java course in Coimbatore.

Why It Matters in Real Life

So, circling back: What is OOP in Java and why is it important? Its real strength comes from making big software projects easier to manage. OOP allows multiple developers to work on their parts without stepping on each other’s toes.

OOP and Full Stack Development

Full stack developers cover both the frontend and backend. Understanding OOP in Java can make your backend logic much better. That’s why a Java Full Stack Developer Course in Coimbatore focuses on OOP right from the start.

Java and Your Career Path

If you're looking to become a software developer, getting a good handle on OOP is a must. Companies love using Java for building big applications because of its OOP focus. Joining a Java training program in Coimbatore can help you get the practical experience you need to be job-ready.

Getting old is interesting. I've always been a middle ground between sports (skateboarding, surfing, jiu-jitsu) and an avid student. Over time, it's clear that you can't keep trying the same tricks, just as you can't study the same way.

Today, as I'm writing an article about event-driven architectures, I realize that final exams in college were much easier, just like it's not as easy to jump the same stairs on a skateboard as I did when I was 18. In the image, you can see my favorite note-taking app, Obsidian, and my Neovim terminal. I'm diving deep into Java, and for that, I'm taking a Spring Boot bootcamp offered by Claro through the DIO Innovation One platform.

Coding: My Escape, My Obsession

Programming—ahh, what a paradox! Sometimes it’s an absolute thrill, and other times, it’s the most stressful thing ever. For me, coding isn’t just a skill; it’s my escape. Whenever life gets heavy, my mind instinctively drifts to programming. New ideas, fresh logic, endless possibilities—it’s like therapy but with syntax errors.

But somewhere along the way, this escape became a full-blown obsession. My four years of engineering? A blur of code, projects, and fixing bugs—mine and everyone else's. I was always working, always solving something. And now, when I look back, I struggle to find those carefree moments of pure fun. Sure, I enjoyed college, but every memory somehow loops back to programming.

I don’t regret it. I don’t claim to be a coding genius either—I’m still learning, still growing. But one thing’s for sure: programming has shaped me in ways I never imagined. It gave me purpose, resilience, and a language beyond words.

Yet, here’s what I’ve realized—life isn’t just about writing perfect code; it’s about writing a story worth remembering. And while programming will always be a part of me, I want to step beyond the screen, embrace new experiences, and create moments that don’t just end in a semicolon.

Because in the end, the best code I’ll ever write is the one that balances passion with life itself.

Network switches

What’s a network switch ?

A switch is a device used in computer networks to connect multiple devices together within a single local area network (LAN). Its main role is to facilitate communication between different connected devices, such as computers, printers, servers, IP phones, etc.

It is a mini-computer which is made up of RAM, ROM, flash RAM, NVRAM, a microprocessor, connectivity ports and even an operating system.

RAM

RAM (Random Access Memory) contains the current configuration of the switch and temporarily stores the MAC address table, which is then processed by the microprocessor.

Microprocessor

The microprocessor is the heart of the switch, responsible for data processing, including switching and creating links between multiple devices.

External memories

External memories, such as flash RAM, ROM, and NVRAM (Non-Volatile RAM), store configuration files , different versions of the IOS , etc ...

Ports

The switch ports are the communication interfaces of the switch. There are several of them, generally 24 for a Cisco switch. Each port is associated with an LED which indicates its status and activity.

How does it work ?

Now how does a switch work to transfer information from one machine to another?

Suppose we have 4 machines: A, B, C and D connected to our switch in ports 1, 2, 3 and 4 as follows:

The switch only works with MAC addresses , so basically we have an empty MAC address table stored in RAM as soon as the switch starts up which looks like this : 

Transmitting data from machine A to machine B happens in the following steps:

Machine A sends a frame to machine B

Once this frame arrives at port 1 (which is the one linked to A), the switch reads the source MAC address and stores it in the MAC address table

The switch reads the destination MAC address and looks for it in the table, if it is not in the table, it broadcasts to all the active machines connected to the switch except the source one.

If the port linked to the machine we want is active, it sends a response frame from which the switch reads the MAC address we were looking for (@B)

Once done, it records the MAC address of B in the table.

This process repeats until the switch reaches what is called "MAC address table stability", that is to say it knows all the MAC addresses of the connected machines and has no more need to broadcast.

Starting and configuring a switch

When it comes to booting a switch, the process is similar to that of a traditional computer system:

POST (Power-On Self Test): The switch performs proper functioning tests on all hardware.

Loading IOS (Internetwork Operating System): The switch operating system is loaded.

Loading the configuration. At this stage we have two cases:

Either the switch already has a startup configuration defined and stored in NVRAM

Either the switch is blank and it is up to us to define the startup configuration when it goes to setup mode

Switch configuration

The configuration of a switch is done through different modes, such as user mode, privileged mode and global configuration mode, which allows access to specific configuration modes, such as interface mode, routing mode, line mode, etc.

And to do all this of course you must first connect the switch with the machine via the console cable and open a terminal emulator

💡 It should be noted that the only machine that can configure the switch is the one connected to it by a console cable, the others are only hosts.

Spent several hours today arguing with the other devs about how to rewrite our enterprise app launcher/updater because right now its pretty much a trojan.

in a nutshell: It currently downloads the individual JARs from our WildFly server, adds them to its classpath via the system classloader, then launches a target main method through reflection, effectively becoming that running process.

Someone from OPS found the list of security exceptions they needed to add to make it work (spoiler its a lot)

I hope the security team is preparing to have a heart attack when we have our meeting Wednesday

I now know the devastating feelings of being laid off of work.

Mind racing.

Am I reasonably competitive in the current Software Engineer job market? Don’t think about that yet.

Oh noes, I’ll have to study for coding interviews *again*. No stop, wait until Monday. Do ANYTHING ELSE.

Cuddle stuffed animal. Hug husband. Call mom, dad, sister. Join their vacation coming up. Stick to good news. Play Minecraft. Fold laundry. Play Overwatch. Plan house decorations. Rewatch Spider-verse. Little things.

Dev Journals #1 -- Code: The Gathering

Hello, there! Call me Mika Snowden, how do you do?

Presumptuous name, isn't it? Thought so too, but the other option was Turing, which is even more presumptuous.

Anyhow, my nickname's presumptuousness isn't the subject of this post. In fact, the subject of the day is a new project I'm starting.

You see, lovelies, I'm a junior developer who would like to become a Java-Angular FullStack Developer. I'm currently in a C#-Angular position, so I'm studying Java to find a new job.

As I still don't have any Java certifications, I've decided to study for them, so I wrote down a couple of project ideas to help me practice. Today, I started one of them and informed my friends about it. Why: Because, unlike my other silly projects, this one might be useful to someone.

I play Magic: The Gathering with my friends, and we have a box where we keep cards anyone can choose from to add to their deck. The issue is: no one ever knows what cards are there, how many, and who the box is with. Since our friendship group has been growing, I've decided to take upon myself the challenge of coding a program that keeps track of said cards.

"Mika, there's already an app for that."

I was informed, but I need an excuse to study Java. What excuse would be better than something you like doing?

So, I'm off to work.

Here, lovelies, are my first day of work fruits. Not much -- I found out I'm easily distracted --, but it's a start.

First, we have my starting object:

I made it work with some setters, after making every attribute private, and we managed to get a nice output on console.

Finally, I brushed off my old database skills, grabbed PostgreSQL and came up with a little table.

Not much, but I'm happy to report project "mtg-repo" (still working on a name) is coming together.

Ta-da!

Learn how to code the object pool pattern by pre-allocating memory and reusing objects. Which can greatly improve performance when reusing short lived objects like bullets and particles.

This tutorial will show you how to create and manage a pool of bullet objects. For example, this is useful in shooter and bullet hell games which have thousands of bullets on the screen.

The tutorial is written in the Java programming language, and uses the free Processing graphics library and integrated development environment.

The object pool pattern can be especially useful with programming languages which use automatic garbage collection like Java, C#, JavaScript, Python, etc.

Since automatic garbage collection can stall your program and reduce your frame rates. The object pool pattern gives you more control over when the garbage collector comes to reclaim the memory.

The downside of the object pool pattern is that it complicates the life cycle of the object. Meaning you need to reset the variables of the object before you can reuse it. Since its variables are unlikely to match the defaults after repeated use.

There are a few ways to implement the object pool pattern, this tutorial will show you one method.

Growing my (code)base

The open-source coding challenge I started back in June is approaching its first API freeze, in other words, version 1.0 ! On Monday night I released v0.9.8 with the following line counts:

+ 66K lines of code (excluding blanks and comments)

+ of which 40K are Java and 22K are C++

Compare with v0.9.0 (from October), which contained 42K lines of code, of which 23K were Java and 15K were C++.
