Today, I explored one of the core concepts of Object-Oriented Programming — Polymorphism in Java. - Understood how a single interface can represent multiple behaviors. - Practiced method overriding and runtime polymorphism. - Implemented real examples using inheritance and dynamic method dispatch. This concept really changed how I think about writing flexible and scalable code. Sharing a small implementation I worked on. #Java #OOP #Polymorphism #CodingJourney #LearningInPublic #SoftwareDevelopment #TAP TAP Academy

🚀 Learning Java Polymorphism! Today I practiced a simple example of runtime polymorphism in Java using method overriding. 🔹 Created a base class payment 🔹 Extended it with UPI and CreditCard 🔹 Overrode the pay() method in each class 🔹 Used dynamic method dispatch to call different implementations 💡 Output: Pay using UPI Pay using Credit Card This helped me clearly understand how Java decides which method to execute at runtime. 📌 Key Concept: Polymorphism allows for one interface with multiple implementations, making code flexible and reusable. #Java #Programming #LearningJourney #Coding #OOP #PlacementsPreparation #Polymorphism #10000Coders Meghana M

Day 38 of Learning Java Today, I explored how a class executes inside the JVM (Java Virtual Machine). Understanding this lifecycle really helped me see what happens behind the scenes when we run a Java program. 🔹 Class Loading   • The JVM loads the class into memory   • It brings the ".class" file into the system 🔹 Linking Phase  • Verification → Checks bytecode for errors  • Preparation → Allocates memory for static variables (default values like 0)  • Resolution → Replaces symbolic references with actual memory references 🔹 Initialization  • Static variables get their actual assigned values  • Static blocks are executed 🔹 Execution  • Methods start running and the program logic is executed 🔹 Destruction  • Objects are destroyed and memory is cleaned up by the Garbage Collector Static variables first get default values during preparation, and later their actual values during initialization. Thanks to my mentor Ashim Prem Mahto for the clear explanations and for always clearing my doubts. #Java #JVM #LearningJourney #Programming #SoftwareDevelopment #BackendDevelopment #CodingLife #JavaDeveloper #TechLearning #StudentLife

#Day35 – Abstraction in Java 🧠 Today’s session completely changed the way I look at Abstraction in Java. 🔹 Key Learnings: ✔ Abstraction → showing essential features while hiding implementation ✔ Achieved using abstract classes & methods ✔ Abstract class → cannot be instantiated ✔ Can contain both abstract & concrete methods ✔ Abstract methods must be overridden in child classes ✔ Constructors, static methods, and variables are allowed in abstract classes ✔ Abstract class can extend another class (abstract or normal) 💡 One interesting insight: Abstract doesn’t just exist in Java — it exists in our life journey too. Many things are unknown (abstract) today, and become concrete over time. Special thanks to TAP Academy, and mentor Harshit T sir for the constant guidance and motivation 🙌 #Java #OOPS #Abstraction #Programming #CodingJourney #Consistency #Learning #TapAcademy

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

🚀 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

Strings are one of the most fundamental yet powerful components in Java, and understanding how they actually work can make a significant difference in writing efficient, reliable, and scalable applications. This guide breaks down key concepts such as how Strings are stored in memory (String Constant Pool vs Heap), why immutability is a core design decision, and how different comparison methods like ==, .equals(), .equalsIgnoreCase(), and .compareTo() behave in real scenarios. These are not just theoretical ideas they directly impact performance, memory optimization, and correctness of code. It also highlights the practical side of working with Strings, including commonly used methods and when to use mutable alternatives like StringBuilder or StringBuffer for better performance in specific use cases. #Java #SoftwareDevelopment #Programming #Coding #JavaDeveloper #TechSkills #BackendDevelopment #ComputerScience #TapAcademy
