Encapsulation in Object-Oriented Programming

Drawbacks of Arrays – Know Before You Use! Arrays are one of the most fundamental data structures, but they come with their own limitations 👇 🔹 Fixed size – once declared, it can’t be changed 🔹 Insertion & deletion are time-consuming 🔹 Requires contiguous memory allocation 🔹 No dynamic resizing capability Understanding these drawbacks helps in choosing the right data structure for efficient problem-solving #DataStructures #Programming #Java #Coding #SoftwareDevelopment #Learning #TechTips

💻 Built a Diamond Pattern in Java using pure logic and nested loops. While practicing DSA fundamentals, I implemented this pattern by understanding how spaces and stars align in each row. This helped me strengthen my control over loops, conditions, and pattern-based problem solving. 📌 Key Learning: Breaking a complex pattern into smaller logical steps makes it much easier to implement. Consistency in solving such problems is what builds strong programming logic. #Java #DSA #Programming #CodingJourney #ProblemSolving #LogicBuilding #Developers #Learning #100DaysOfCode

Today I learned about Runtime Polymorphism in Java. Runtime Polymorphism is achieved using method overriding, where a subclass provides its own implementation of a method defined in the parent class. It helps in achieving dynamic behavior, meaning the method call is resolved at runtime instead of compile time. Example: I created an Animal class with a sound() method, and then different animals override it with their own sound. Dog → Barks Cat → Meows This shows how the same method behaves differently based on the object. #Java #Programming #OOP #Learning #CodingJourney

🚀 Exploring the principles of Object-Oriented Programming 🔹 Inheritance – reusing code effectively 🔹 Encapsulation – managing and protecting data 🔹 Polymorphism – one interface, multiple forms 🔹 Abstraction – hiding complexity Building a strong foundation in programming. 💻✨ #Java #OOP #Programming #LearningJourney #SoftwareDevelopment #consistency

Today I practiced a simple yet important concept of Object-Oriented Programming — Method Overriding. 🔹 Created a parent class (Shape) with a draw() method 🔹 Overrode the same method in child classes Circle and Rectangle 🔹 Demonstrated runtime polymorphism using a parent class reference 💡 This example clearly shows how Java decides which method to call at runtime based on the object type. 📌 Output: Drawing a Circle Drawing a Rectangle ✨ Concepts Covered: ✔ Inheritance ✔ Method Overriding ✔ Runtime Polymorphism #Java #OOP #Programming #Coding #MethodOverriding #Polymorphism #LearningJourney #SoftwareDevelopment #JavaDeveloper

🚀 Understanding Inheritance in Object-Oriented Programming (OOP) As part of my learning journey in programming, I explored one of the core concepts of OOP — Inheritance. Inheritance allows a class to acquire properties and behaviors from another class, promoting code reusability, scalability, and better structure in software development. 📌 In this visual, I’ve covered: • Introduction to Inheritance • Single Inheritance • Multilevel Inheritance • Hierarchical Inheritance • Multiple Inheritance • Hybrid Inheritance Each type demonstrates how classes can be related and extended in different ways, making programs more efficient and modular. 💡 This concept is widely used in languages like Java, Python, and C++ and is essential for writing clean and maintainable code. #TapAcademy #OOP #Java #Programming #SoftwareDevelopment #LearningJourney #Coding #ComputerScience

Saving this as a reminder of what long-term consistency looks like. 1070/2002 days of code and 1800+ LeetCode questions is not about talent, it’s about discipline. As I work on my own 365 days of code and data journey, posts like this keep me going. Inspiring work, Shivam. 🔥

Day 4: Constructors After understanding classes, objects, encapsulation, and access modifiers, the next step is learning how objects get their initial values. That is where constructors come in. A constructor is used to initialize an object when it is created. In Java, it has the same name as the class, has no return type, and runs automatically when the object is created. Simple idea, but very important, because it helps us create objects in a cleaner and more intentional way. #Java #OOP #Programming #SoftwareEngineering #ComputerScience #koofkee

🚀 #Day11 of #111DaysOfLearningForChange Continuing my learning consistency challenge with Code for Change. Today, I continued with Object-Oriented Programming (OOP) in Java, focusing on how objects are created and managed. Topics covered: • Encapsulation • Constructors • Types of Constructors: – Parameterized Constructor – Non-Parameterized Constructor – Copy Constructor • Destructors While practicing, I focused on how data can be kept safe inside a class and how objects are created and initialized properly. This session gave me a clearer understanding of how real-world programs are structured using OOP concepts. Consistently learning and improving every day. #CodeForChange #111DaysOfLearningForChange #Day11 #OOP #Consistency #DSAwithJava

🚀 Day 7 of My Java Learning Journey – Advance Arrays Today, I explored advanced concepts of arrays in Java, moving beyond basics into more structured and flexible data handling. Here’s what I learned 👇 🔹 Working with 2D Arrays (Matrix) → Understanding rows & columns using nested loops 🔹 Exploring Jagged Arrays → Handling arrays with different column sizes 🔹 Passing arrays to methods → Learning how arrays behave when passed as arguments 🔹 Returning arrays from methods → Building reusable and modular code 💡 This practice helped me realize how arrays can represent complex data structures and how methods make code more organized and reusable. 📌 Key Learning: Mastering arrays is essential because they are the building blocks for advanced topics like data structures and algorithms. 💻 Small steps every day = Big progress over time! #Java #Programming #CodingJourney #Arrays #2DArray #JaggedArray #100DaysOfCode #Learning #JavaDeveloper
