🚀 Learning OOPs with Java – Abstraction & Polymorphism 💻 Today I practiced an important concept of Object-Oriented Programming: Abstraction with Polymorphism. 🔹 I created an abstract class Pen with an abstract method draw(). 🔹 Then I implemented two subclasses: BluePen and RedPen. 🔹 Both classes override the same method in their own way. 👉 This shows how one method can behave differently (Polymorphism). 💡 Key Learning: Abstract class defines structure, not implementation Subclasses must override abstract methods Same reference, different objects = powerful concept! 📌 Code Output: Pen -> Blue Pen -> Red I'm improving step by step and enjoying the journey of learning Java 🚀 #Java #OOP #Programming #Coding

🚀 Day 16/45 – Understanding Abstraction in Java On Day 16 of my Java learning journey, I explored Abstraction, one of the core principles of Object-Oriented Programming. Abstraction focuses on hiding implementation details and showing only the essential functionality to the user. 📚 What I Learned Today Today I learned: ✔ What abstraction is and why it is important ✔ How to use abstract classes in Java ✔ Understanding abstract methods (methods without body) ✔ How abstraction works with inheritance 💻 Practice Work To apply my learning, I implemented: • An animal example using abstract class • A shape example demonstrating abstraction 🎯 Key Takeaway Abstraction helps simplify complex systems by hiding unnecessary details and focusing on what is important. It plays a key role in building clean and scalable applications. Step by step, I am gaining a deeper understanding of OOP concepts. #Java #Programming #LearningInPublic #CodingJourney #SoftwareDevelopment #OOP

🚀 Day 2 of My Java Learning Journey Today’s focus: Operators & Input/Output — the building blocks of logic and interaction. From performing calculations ➕➖✖️➗ to handling real-time user input ⌨️ and displaying output 🖥️, I’m starting to see how programs actually think and respond. 💡 Key takeaways: • Understanding how different operators shape decision-making • Learning how input/output connects users with code • Writing small programs that feel more “alive” Every line of code is getting me one step closer to becoming a better developer. Consistency > Motivation. Showing up every day. 🔁 #Java #LearningInPublic #100DaysOfCode #Programming #CodingJourney #Developers #TechSkills #JavaBasics #StudentDeveloper #BuildInPublic

🚀 Day 14 of Java Learning 📌 Today’s Topic: Instance Block vs Static Block vs Constructor 💡 Here’s what I learned: ✔️ Static Block → Executes only once (at class loading time) ✔️ Instance Block → Runs every time an object is created ✔️ Constructor → Initializes the object after instance block ✔️ Execution Order → Static → Main → Instance → Constructor → Method 🧠 Key Takeaways: 🔹 Static blocks are useful for one-time setup 🔹 Instance blocks run before constructors 🔹 Constructors help in object initialization 🔹 Understanding execution flow is super important for interviews 💻 Practiced with code examples to understand real execution flow 🔥 📈 Consistency is the key — one step closer to mastering Java! #Java #Programming #Coding #Developers #OOP #100DaysOfCode

90% of your app uses Strings… but do you really know them? Today I spent some time understanding *Strings in Java*… and honestly, it’s deeper than it looks At first, I thought strings are just text we use in programs. But today I learned things like: * Strings are *immutable* (they can’t be changed once created) * Difference between *Heap Memory & String Pool (SCP)* * Why using equals() is important instead of == * And how small things can affect *performance & memory* It’s interesting how such a basic concept plays a huge role in real applications Still learning step by step… but enjoying the process If you’re learning Java too, what topic are you currently on? 👇 #Java #LearningJourney #Coding #Programming #BeginnerDeveloper #SoftwareDevelopment #100DaysOfCode

Learning Polymorphism in Java Today I explored one of the core concepts of OOPs – Polymorphism. It allows a single method to perform multiple behaviors depending on the object. 🔹 Covered: Compile-time polymorphism (Method Overloading) Runtime polymorphism (Method Overriding) Real examples with Java code Understanding this concept improves code flexibility, reusability, and scalability. 📘 Sharing my handwritten notes + examples for better understanding. #Java #OOP #Polymorphism #Programming #CodingJourney #Learning #JavaDeveloper #SoftwareDevelopment

Reversed String in Java | Easy Logic + Coding 💡 Strong fundamentals are essential to become a confident developer. This example shows how String Reversal works using simple logic: • Start with a given string • Traverse the string from last character to first • Use loop or built-in methods • Form the reversed string Practicing these types of problems improves logical thinking and strengthens coding basics. 📊 Example Input : LIVE Output : EVIL 🎥 I’ve also created a short video explaining this concept with code: YouTube link : https://lnkd.in/eKH2JJwa #Java #Programming #ProblemSolving #Coding #SoftwareDevelopment #Learning #CSE #Developers #LogicBuilding #String

📆 Day 227 & 228 of 365 Days Focused on practicing DSA basics using Python along with continued Java practice. Worked on strengthening fundamentals like arrays, loops, and basic problem-solving patterns in Python, while also maintaining consistency with Java to improve logic and coding flow. These sessions were all about building a strong foundation across both languages and getting more comfortable with solving problems step by step. #Python #Java #DSA #ProblemSolving #CodingPractice #Developers #Programming #TechJourney #BuildInPublic #Learning #SoftwareEngineering

🚀 Mastering Sequenced Collections in Java (LinkedHashSet & LinkedHashMap) Ever struggled with maintaining insertion order while working with collections? 🤔 That’s where Sequenced Collections in Java come into play! Using classes like LinkedHashSet and LinkedHashMap, we can solve real-world problems where order + uniqueness + performance matter. From removing duplicates while preserving order ➡️ to building LRU Cache and finding non-repeating elements, these collections are incredibly powerful in both interviews and real-time applications 💡 I’ve compiled a set of practical and unique programs demonstrating how these collections can be used effectively. 📄 Attaching a document with all examples — feel free to explore and try them out! #Java #Collections #Java21 #LinkedHashMap #LinkedHashSet #Programming #Developers #Coding #InterviewPrep #TechLearning
