Java Exception Handling: ArrayIndexOutOfBoundsException & ArithmeticException

Did you know this about Java Wrapper Classes? In Java, not all objects are created equal. Some wrapper classes cache frequently used values to improve performance and reduce memory usage. This means Java may reuse existing objects instead of creating new ones — something that can even affect how == behaves! Understanding this small internal optimization can make a big difference in interviews and real-world coding.

📘 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

📘 Day 25 | Core Java Series Polymorphism is one of the core pillars of Object-Oriented Programming in Java. It allows the same method to behave differently in different situations. Remember this: Overloading → Compile time Overriding → Runtime Once polymorphism is clear, Java OOP concepts start to connect naturally. 📌 Save this for revision 💬 Feedback is welcome #Java #CoreJava #OOP #Polymorphism #LearningInPublic

🎥 New Video in My Java Arrays Series – Array Traversal in Java After introducing the basics of Arrays in Java, I’ve uploaded my second video, where I explain Array Traversal — how to access and work with each element step by step. 👉 If you’re a beginner in Java, this might help you. 👍 I’d really appreciate your support — watch, like, and share if you find it useful. Your feedback really helps me improve. #Java #Programming #LearnJava #Arrays #CodingJourney #StudentDeveloper #TechLearning #LinkedInCreators #Consistency

🚀 Today I Learned – Inheritance in Java •Today, I learned about Inheritance, the second pillar of Object-Oriented Programming (OOP) in Java. 🔹 Inheritance allows one class (child) to acquire properties and behaviors from another class (parent). 🔹 In Java, inheritance is achieved using the extends keyword. 🔍 Key Concepts I Covered: ✅ Single Inheritance – One parent → One child ✅ Multilevel Inheritance – Grandparent → Parent → Child ✅ Hierarchical Inheritance – One parent → Multiple children ✅ Hybrid Inheritance – Combination of inheritance types (concept exists) ❌ Multiple Inheritance – Not supported in Java classes 💎 Diamond Problem •I also understood why Java does not support multiple inheritance with classes — to avoid ambiguity when two parent classes contain the same method. Understanding inheritance helps in: •Code reusability •Better organization •Building scalable applications #Java #OOP #Inheritance #LearningJourney #SoftwareDevelopment #CoreJava #Programming #TapAcademy

🔹 Java Concept of the Day 📌 Can we use string as a variable name in Java? Yes ✅ Java is case-sensitive, so: String → Predefined class (used to store text) string → Just a normal variable name Example: int string = 10; System.out.println(string); ✔ Output: 10 But ⚠ this is not a good practice because it creates confusion between the String class and the variable name. 💡 Best Practice: Always use meaningful and clear variable names like: int number = 10; 🧠 Key Learning: In Java, identifiers are case-sensitive, but good naming conventions make your code more readable and professional. #Java #Programming #CodingBasics #DSA #LearningInPublic #JavaDeveloper

❌ Faced a NullPointerException today while practicing Java. Lesson learned: Always check if an object is null before calling methods on it. Example: Instead of directly using: object.method() Use: if(object != null) Errors are the best teachers in programming 💻 #Java #LearningJourney #100DaysOfCode
