Java Operators: Arithmetic, Relational, Logical, Assignment

📘 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.

Variables are the foundation of every Java program 🧱 In Part 4 of my Java Basics to Advanced series, I explain variables and data types in a simple and practical way. 👇 Which data type did you learn first in Java? #Java #JavaBasics #LearnJava #Programming #SoftwareDevelopment #JavaDeveloper #JavaProgramming

🎯 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

📘 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

📘 Day 14 | Core Java Series Strings in Java are not all the same. This visual explains the difference between: 👉 String 👉 StringBuilder 👉 StringBuffer Remember this: String → Immutable StringBuilder → Fast & Mutable StringBuffer → Thread-safe Choosing the right one improves performance and clarity. 📌 Save this for revision 💬 Feedback is welcome #Java #CoreJava #LearningInPublic #JavaBasics #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

Java Scanner Class Explained | Beginner Friendly Core Java. The Scanner class is one of the most beginner-friendly ways to take user input in Java. This short video explains: - What Scanner class is - How it uses System.in - Commonly used Scanner methods Ideal for beginners starting their Java programming journey. 🎥 Watch more Java tutorials on my YouTube channel: https://lnkd.in/gwqCZWkg #Java #CoreJava #JavaProgramming #JavaBasics #SoftwareDevelopment #LearnToCode #Programming #JavaTutorial

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

📘 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

Understanding Static in Java 🚀 Today I learned about the static keyword in Java and created this example to demonstrate three important concepts: ✅ Static Variable - Shared by all objects of the class ✅ Static Block - Executes once when the class is loaded ✅ Static Method - Can be called without creating an object In this Student class example: 1.schoolName is static, so all students share the same school 2.The static block runs first, before the main method 3.The add() method is static and can be called directly using the class name When we change Student.schoolName, it updates for all student objects immediately! #Java #Programming #Learning #JavaDevelopment #CodingJourney #SoftwareDevelopment
