Day 9: Interfaces After abstraction, the next important idea is interfaces. An interface defines a contract. It tells a class what behavior it must provide, without giving the full implementation itself. In Java, a class uses `implements` to follow that contract. This makes code more flexible, because different classes can follow the same interface in their own way. #Java #OOP #Programming #SoftwareEngineering #ComputerScience #koofkee

Today I learned about Abstraction in Java. Abstraction is a core concept of Object-Oriented Programming that focuses on hiding implementation details and showing only essential functionality. To understand it better, I implemented a simple payment system using an abstract class. Through this example, I understood: - How abstract classes work - How implementation is hidden from the user - How different behaviors can be achieved using the same structure I’m continuing to strengthen my understanding of Java and OOP concepts. #Java #Abstraction #OOP #LearningJourney

Day 43-What I Learned In a Day(JAVA) Today I worked on String concepts in Java and practiced some interesting problems. What I learned: Creating and using strings in Java Converting a number into an array using strings Handling characters using charAt() Problems I practiced: ✅ Created and manipulated strings ✅ Converted number -array using string ✅ Moved zeros to the end of an array These problems helped me understand how strings and arrays work together and improved my problem-solving skills. Learning step by step and getting better every day! Practiced 👇 #Java #CodingPractice #LearningJourney #Programming #100DaysOfCode

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

Day 45-What I Learned In a Day (JAVA) Today I explored some important concepts related to static in Java: 🔹 Static Method Learned how static methods belong to the class and can be called without creating an object. 🔹 Static Initializer (Static Block) Understood how a static block is executed only once when the class is loaded. 🔹 Single-Line Static Initializer Explored how we can initialize static variables in a single line. 🔹 Multi-Line Static Initializer Learned how to use static blocks for complex initialization logic.

Today, I explored one of the most important concepts of Object-Oriented Programming — Inheritance. Inheritance allows one class to acquire the properties and behavior of another class, making code more reusable and structured. I practiced three types of inheritance in Java: 1. Single Inheritance One class inherits from another. #oopsconcept #inheritance #java #codingjourney

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

Day 5: Inheritance As programs grow, many classes start sharing similar properties or behavior. That is where inheritance becomes useful. Inheritance allows one class to take the properties and behavior of another class. In Java, we use `extends` to create that relationship. This helps reduce repetition and makes code easier to organize when classes are related. #Java #OOP #Programming #SoftwareEngineering #ComputerScience #koofkee
