📘 Day 30 | Core Java Series The Collections Framework is where Core Java concepts meet real-world programming. This visual explains the basics: 👉 List 👉 Set 👉 Map Remember this: List → Order matters Set → Uniqueness matters Map → Key–Value matters This marks the end of my Core Java learning series. Advanced Java topics coming next 🚀 📌 Save this for revision 💬 Feedback is welcome #Java #CoreJava #Collections #LearningInPublic #Programming

📘 Day 28 | Core Java Series Encapsulation is one of the most important pillars of Object-Oriented Programming in Java. It helps protect data and allows controlled access using methods. Remember this: Encapsulation = Data hiding + Controlled access If this concept is clear, writing secure and maintainable code becomes much easier. 📌 Save this for revision 💬 Feedback is welcome #Java #CoreJava #OOP #Encapsulation #LearningInPublic

🎯 Today’s Java lesson: Encapsulation Learned how data hiding, private variables, getters, setters, and validation work together to protect data and keep code clean, secure, and maintainable. One step closer to writing real-world Java code 💻☕ #Java #OOP #Encapsulation #LearningJourney #Programming

🚀 Practicing Core Java – Constructor Concept Today I implemented a Parameterized Constructor example in Java where employee details are initialized using constructor and static variable is shared across objects. Understanding the difference between: ✔ Instance Variables ✔ Local Variables ✔ Static Variables Step by step improving my Java fundamentals 💻 #Java #CoreJava #Constructors #Programming #Learning

📘 Day 15 | Core Java Series Java has primitive data types, but collections work only with objects. That’s where Wrapper Classes come in 👇 This visual explains: 👉 Primitive vs Wrapper mapping   👉 Why wrapper classes are needed  Remember this: Primitive → value   Wrapper → object  Once this is clear, collections and autoboxing make much more sense. 📌 Save this for revision 💬 Feedback is welcome #Java #CoreJava #LearningInPublic #JavaBasics #Programming

📘 Day 20 | Core Java Series The `static` keyword is one of the most important concepts in Java. This visual explains: 👉 static variables 👉 static methods 👉 static blocks 👉 static classes Remember this: static → class level non-static → object level Once this is clear, Java execution flow makes much more sense. 📌 Save this for revision 💬 Feedback is welcome #Java #CoreJava #LearningInPublic #JavaBasics #Programming

Practiced string filtering in Java using startsWith() and toLowerCase() 💻 Learned how to handle case-insensitive comparisons and loop through arrays efficiently. Small logic, but strong fundamentals 🚀 #Java #CoreJava #Programming #LearningByDoing #SoftwareEngineer #JavaDeveloper

Understanding Class and Object in Java (OOP Basics) In Java, Class and Object are the foundation of Object-Oriented Programming. 🔹 Class A class is a blueprint or template that defines properties (variables) and behaviors (methods). Example: Dog class defines name, color, height, and actions. 🔹 Object An object is a real-world instance of a class. Example: Tommy is an object created from the Dog class with actual values. 📌 Key Takeaway Class → Design / Blueprint Object → Real implementation Multiple objects can be created from a single class Promotes reusability, modularity, and clean code #Java #OOP #ObjectOrientedProgramming #ProgrammingBasics #JavaDeveloper #LearningJava #Coding
