Implementing Armstrong Number Logic in Java with Scanner and Loops

Functional Programming 's building blocks in Java Hi all, the slides deck linked here is a short introduction to functional programming features introduced with Java 8. The next article will go one step beyond with advanced features as brought by the VAVR library. I hope it will be useful. Happy coding...

Hello LinkedIn! Today I learned about Constructors in Java, an essential part of Object-Oriented Programming. 📌 What I understood: ✅ A Constructor is a special method used to initialize objects ✅ Constructor name must be same as the class name ✅ It does not have a return type ✅ Types of constructors – Default & Parameterized ✅ Helps in setting initial values to object properties Understanding constructors is helping me write more structured and object-oriented programs. Step by step, moving deeper into Java and OOP concepts 💻🔥 Consistency + Practice = Progress #Java #OOP #Constructor #Programming #LearningJourney #Developer

As part of strengthening my Core Java fundamentals, I recently explored Method Overloading, a key concept in Object-Oriented Programming. Method Overloading enables a class to have multiple methods with the same name but different parameter lists (varying in number, type, or order of parameters). This is resolved at compile time and is an example of compile-time polymorphism. 🔎 Key Takeaways: • The method name remains the same • The parameter list must differ • Changing only the return type is not sufficient • Improves code readability and reusability 💡 Practical Implementation: I implemented overloaded methods for arithmetic operations such as addition, subtraction, and multiplication using different data types (int, float, double). This helped me understand how Java determines which method to invoke based on the arguments passed. Building strong fundamentals in Java is helping me develop a deeper understanding of OOP principles and writing cleaner, more maintainable code. #Java #CoreJava #OOPS #MethodOverloading #Programming #LearningJourney #SoftwareDevelopment

📘 Day 15 – Java Number Program Series Continuing my Java fundamentals journey with number-based logic programs 💻🧠 📌 Today’s Programs: 1️⃣ Reverse a number 2️⃣ Count the number of digits in a number 3️⃣ Check whether a number is a Strong number 4️⃣ Check whether a number is an Armstrong number 5️⃣ Print Fibonacci series up to a given number 💡 Day 15 Takeaway: Today was less about syntax and more about mastering number logic and mathematical reasoning in Java. #Java #JavaDeveloper #CoreJava #Programming #ProblemSolving #SoftwareDevelopment #CodingJourney #JavaLearning

Day 31/100 – Revisiting Java Arrays & Enhanced For Loop ☕ Today I revisited the Enhanced For Loop (for-each loop) in Java while practicing array traversal. Instead of using indexes like a traditional for loop, the enhanced loop lets us directly iterate through each element of the array, making the code cleaner and easier to read. Example idea: for(int num : arr) → goes through each element one by one. Key takeaways: • Cleaner way to traverse arrays and collections • Reduces chances of index-related errors • Makes code more readable and concise Small concepts like these build a stronger programming foundation over time. Still learning. Still consistent. 🚀 #100DaysOfCode #Java #Programming #CodingJourney #SoftwareDevelopment #Consistency #LearningInPublic

🚀 Day 14 – Solving Array Challenges in Java Not every day is about learning a new concept. Some days are about strengthening what we already know by solving more challenges 💪 Today, I focused on solving multiple array-based problems to improve my logical thinking and problem-solving skills in Java. 🧩 Problems I Solved: ✔ Find the Sum and Average of all elements in an array ✔ Count the Number of Occurrences of a specific element ✔ Find the Maximum and Minimum element in an array ✔ Check whether the given array is Sorted ✔ Create a new array after Deleting a specific element 🛠 Skills Improved: • Loop mastery (for, while) • Conditional logic • Array traversal techniques • Edge case handling • Writing clean and modular code 💡 Key Takeaway: Consistency matters more than speed. Every small challenge solved builds stronger fundamentals in programming. Step by step improving problem-solving ability and confidence in Core Java 🚀 #100DaysOfCode #Java #CoreJava #DSA #ProblemSolving #Arrays #DataStructures #Programming #CodingJourney #DeveloperLife #SoftwareDeveloper #BackendDeveloper #JavaDeveloper #LearningJourney #TechSkills

Today, I focused on understanding and practicing Methods in Java, one of the most important building blocks of programming. Methods help in writing clean, reusable, and organized code. By breaking a large problem into smaller tasks, methods improve readability, maintainability, and efficiency of programs. 🔹 Explored method declaration and definition 🔹 Practiced return types and void methods 🔹 Worked with parameters and arguments 🔹 Implemented method overloading 🔹 Solved multiple problems using modular approach Through this practice, I enhanced my logical thinking and gained deeper clarity on how structured programming works in real-world applications. Consistent practice of fundamentals is helping me build a strong foundation in Java. 💻✨ #Java #Programming #LearningJourney #Coding #SoftwareDevelopment #CoreJava#TapAcademy

Hello Connections 👋 Today I practiced a Java concept called Anonymous Class. An Anonymous Class is a class without a name that is created and instantiated at the same time. It is mainly used when we want to override a method for one-time use without creating a separate class. In the example above: • I created a Parent class with a method "message()" • Then I used an Anonymous Class to override that method • When the object calls "obj.message()", the overridden method from the anonymous class is executed 💡 This helps developers write quick implementations and reduce unnecessary class creation. Learning and sharing small concepts every day to strengthen my Java programming fundamentals 🚀 #Java #JavaProgramming #AnonymousClass #Coding #LearningJourney

✨DAY-16: 💻 From Messy Variables to Clean Arrays – The Power of Smart Coding! This meme perfectly shows the difference between writing code without arrays and using arrays in Java. 🔴 Without Arrays: Java Copy code int mark1 = 86; int mark2 = 71; int mark3 = 90; int mark4 = 65; 👉 Too many variables 👉 Hard to manage 👉 Not scalable 👉 Messy and inefficient Imagine handling 100 student marks like this 😅 🟢 With Arrays: int[] marks = {86, 71, 90, 65, 79}; ✅ Organized ✅ Easy to access using index ✅ Simple to loop ✅ Clean and scalable Arrays help us store multiple values of the same type in a single variable, making our code structured and efficient. 📌 Daily Life Lesson: When things are unorganized, life feels stressful. When structured properly, everything becomes simple and productive. Learn concepts clearly — code smarter, not harder 🚀 #Java #Programming #Arrays #CodingLife

📚 Understanding Association in Object-Oriented Programming (OOP) In Java, Association represents a relationship between two classes where objects interact with each other. It is mainly divided into two types: 🔹 Aggregation (Weak Relationship) The secondary object can exist independently of the primary object. Example: A mobile phone and a charger. Even if the phone is lost, the charger can still be used. 🔹 Composition (Strong Relationship) The secondary object is completely dependent on the primary object. Example: A mobile phone and its operating system. If the phone is destroyed, the OS cannot exist separately. Understanding these relationships helps in designing better object-oriented systems with clear structure and maintainability. #Java #OOP #Association #Aggregation #Composition #Programming #SoftwareDevelopment
