Java Exception Handling: throw vs throws

I used to think learning Java was just syntax and code… until it proved me wrong. 💡 But over time, I realized something — it’s not about how much you cover, it’s about how much you truly understand. There were moments where I could explain a concept… but couldn’t apply it confidently. That’s when it hit me — I wasn’t learning deeply, I was just moving fast. ⚡ So now, I’m changing my approach. Slowing down. Asking more questions. Breaking things until I actually understand how they work. 🧠 This journey is no longer about “finishing Java” — it’s about building strong fundamentals that actually stay. I’ll be sharing what I learn along the way — the small insights, mistakes, and lessons that make a difference. 📌 What’s one concept you thought you understood… until you had to actually use it? 🤔 #Java #LearningInPublic #DeveloperJourney #Consistency #Growth

🚀 Understanding Method Overriding & super Keyword in Java 💻 One of the most important OOP concepts in Java is Method Overriding — and how we can still access the parent class method using the super keyword. 📌 Concept Highlight: When a subclass overrides a method from its superclass, we can still call the original (overridden) method using: 👉 super.methodName() 💡 Real Practice Scenario: We were given a problem where: A subclass overrides a method But we need to call both: ✔ Child class method ✔ Parent class method 🎯 Expected Output: Hello I am a motorcycle, I am a cycle with an engine. My ancestor is a cycle who is a vehicle with pedals. 🧠 Key Learning: ✔ Method Overriding allows runtime polymorphism ✔ super keyword helps access parent class methods ✔ Promotes code reuse and clean design ✔ Very common in interviews & coding platforms 💻 Takeaway: 👉 Always remember: Even if a method is overridden, the original behavior is still accessible using super 📚 Perfect for: ✔ Java beginners ✔ Students preparing for interviews ✔ Anyone learning OOP concepts #Java #OOP #MethodOverriding #SuperKeyword #JavaProgramming #CodingPractice #InterviewPreparation #LearnJava

#Day_13 of My Java Learning Journey – Writing Functions in Java Today I practiced how to create functions (methods) in Java, and I built a simple program to check whether a number is Even or Odd. 🔥 What I learned today: ✔ How to create a boolean function ✔ How to use if-else conditions inside a method ✔ How to return true/false ✔ How to call a method inside the main() function ✔ How to print the result in the console 🧩 Example I worked on: I created a method IfEven(int a) that: Prints whether the number is Even or Odd Returns a boolean value (true for even, false for odd) This helped me understand functions more clearly and how they improve code structure and reusability. #Java #LearningJourney #100DaysOfCode #Coding #Developer #JavaBeginners #OOP #CodeNewbie

I’m not a Java expert (yet). I’m learning it — and sharing along the way. 🚀 This week: Java Basics. Here’s what actually stuck with me 👇 🔹 Java is not just a language — it’s a platform JDK → JRE → JVM These 3 layers are the foundation. Most beginners skip this… and it shows later. 🔹 “Write Once, Run Anywhere” — but why? Because Java doesn’t compile to machine code. It compiles to bytecode, which runs on the JVM. That’s what makes Java platform-independent. 🔹 8 Primitive Data Types — everything else is reference int, long, double, char, boolean… If it’s not one of these → it stores a memory address, not the actual value. Sounds small, but this changes how memory and performance work. 🔹 OOP = 4 pillars Instead of just memorizing definitions, I focused on understanding them with code examples 👨💻 (Encapsulation, Inheritance, Polymorphism, Abstraction) 🤔 Still figuring this out: ❓ When should we use an abstract class vs an interface? Would love your insights 👇 📌 Learning in public = built-in accountability If you're on the same journey, let’s grow together. #Java #JavaLearning #LearningInPublic #SoftwareDevelopment #JavaDeveloper #CodingJourney

🚀 Day 1 of my Java journey! Today I spent 4 hours learning Java from scratch, and here's what I covered: ✅ How Java works (JVM, compile once, run anywhere) ✅ Setting up my development environment ✅ Variables — int, double, String, boolean ✅ Reading user input with Scanner ✅ Arithmetic operators ✅ String methods ✅ If/else logic and decision making ✅ Random numbers Java is a powerful, in-demand language for backend development and I am committed to learning it every day to become a Java developer. 💪 This is Day 1 of many.

🚀 Mastering Java Switch Statements – From Basic to Advanced I recently practiced different ways of using switch statements in Java, and here’s what I learned step-by-step 👇 🔹 1. Traditional Switch (Basic) ➡️ Used multiple case blocks with break statements ➡️ Works but repetitive and lengthy 🔹 2. Grouping Cases ➡️ Combined multiple cases using commas ➡️ Cleaner and reduces duplication 🔹 3. Switch with Arrow (->) ➡️ Introduced modern syntax ➡️ No need for break ➡️ More readable and concise 🔹 4. Using Variable for Output ➡️ Stored result in a variable ➡️ Better for structured and reusable code 🔹 5. Switch as Expression ➡️ Directly returns value ➡️ Makes code shorter and powerful 🔹 6. Using yield Keyword ➡️ Used in block-style switch expressions ➡️ Helps return values explicitly ➡️ Converted output to uppercase for better formatting ✨ Key Takeaways: ✔ Code readability improved step by step ✔ Reduced redundancy ✔ Learned modern Java features ✔ Understood difference between statement vs expression 🙏 Grateful for the Guidance: A special thanks to my mentor Anand Kumar Buddarapu sir for guiding me and encouraging me to explore Java pattern programming and logical coding techniques.

#Day_10 of My Java Learning Journey ! Today I explored Java String Methods and learned how powerful and flexible string handling can be in Java. (1) Concatenation (+ and .concat()) (2) String length (3) Searching with .contains() (4) Converting to uppercase (5) Case-sensitive & case-insensitive comparison (6) Replacing characters (7) Finding index positions Understanding these methods is helping me write cleaner and more efficient Java code. Step by step, getting better every day! 💻 #Java #StringMethods #CodingJourney #100DaysOfCode #Learning #Developer

I almost gave up on Java in my second month of learning it. The verbosity was driving me crazy. My friends were building cool stuff with Python in 10 lines. I was still writing boilerplate. But my mentor said something I never forgot. "Java doesn't let you cut corners. And that's exactly why enterprises trust it." Slowly it started making sense. The structure. The strictness. The way it forces you to think before you type. Fast forward to today, I've built and shipped systems that handle millions of requests. And Java is still at the core of every single one. The language didn't change. My patience did. If you're a beginner struggling with Java right now, just give it a little more time. It clicks. And when it does, it really clicks. 🙌 What was YOUR turning point with Java? Tell me in the comments 👇 #Java #CodeLife #SoftwareEngineering

🚀 Day 13 of My Java Journey Today I explored Java Keywords — the building blocks of Java programming 💻 🔑 Key Learnings: • Java has 53 reserved keywords • Keywords are predefined & cannot be used as identifiers • All keywords are written in lowercase • Learned categories: 👉 Program Control (if, else, for, while...) 👉 OOP Concepts (class, interface, extends...) 👉 Miscellaneous (import, package, this...) 💡 Interesting Fact: "true", "false", and "null" are reserved literals, not keywords! ⚠️ Bonus Tip: Keywords like "goto" and "const" are reserved but not used in Java Aman Soni 📌 Understanding keywords is the first step to mastering Java syntax and logic. #Java #Programming #CodingJourney #100DaysOfCode #JavaDeveloper #Learning #Tech #Beginners #CodeNewbie #DeveloperJourney

Day 44 of Java Learning Today, I explored Functional Interfaces in Java — a key concept that powers modern Java programming, especially with lambda expressions. 💡 A Functional Interface is an interface that contains exactly one abstract method. It may have multiple default or static methods, but only one abstract method defines its core functionality. ✨ Why Functional Interfaces matter: Enable lambda expressions for cleaner and shorter code Improve readability and maintainability Support functional programming style in Java Widely used in streams and APIs 🔍 Common Built-in Functional Interfaces: Runnable Callable Comparator Consumer Supplier Function ⚡ Key Insight: Using the @FunctionalInterface annotation ensures that the interface follows the rule of having only one abstract method, helping avoid mistakes during development. #Java #FunctionalProgramming #LambdaExpressions #CodingJourney #LearningJava
