Understanding the Main Method in Java

Day 18 of #50DaysOfCode – Java Today’s challenge: Calculate the Product of Digits in a Number! A simple yet logical problem that enhances understanding of loops and arithmetic operations 💡 📘 Example: Input → 234 Output → 24 (2 × 3 × 4 = 24) #Java #CodingChallenge #50DaysOfCode #CodeEveryday #LogicBuilding #LearnToCode #ProgrammingBasics

Day 19 of #50DaysOfCode – Java Today’s challenge: Count the number of even and odd digits in a given number! ✨ This problem helps strengthen your understanding of loops, modular arithmetic, and conditional logic — all key concepts in programming 💪 #Java #CodingChallenge #50DaysOfCode #ProgrammingBasics #LearnToCode #CodeNewbie #LogicBuilding #DailyCoding

Day 20 of #50DaysOfCode – Java Today’s task: Find the sum of all odd digits in a given number! 🔢 A simple yet logical exercise that helps strengthen your understanding of loops, conditionals, and digit manipulation. 💡 👉 This program takes a number as input and calculates the total of its odd digits using a while loop and the modulus operator. #Java #CodingChallenge #50DaysOfCode #LearnToCode #ProgrammingBasics #LogicBuilding #CodeEveryday #JavaProgramming

Day 22 of #50DaysOfCode – Java 🚀 Today’s challenge was to check whether a number is a Strong Number 💪 A Strong Number is a number in which the sum of the factorials of each digit equals the original number. Example: 145 → 1! + 4! + 5! = 145 ✔️ (Strong Number) This problem helped me practice: ✔️ Using loops inside loops ✔️ Calculating factorials ✔️ Strengthening logic-building skills #Java #CodingChallenge #50DaysOfCode #LogicBuilding #ProgrammingBasics #LearnToCode #DailyCoding #StrongNumber

“𝒀𝒆𝒉 𝒐𝒓𝒊𝒈𝒊𝒏𝒂𝒍 𝒘𝒂𝒍𝒂 𝒌𝒚𝒖𝒏 𝒃𝒂𝒅𝒂𝒍 𝒈𝒂𝒚𝒂?” If you’ve ever asked that while cloning objects in Java — this post is for you! Here’s a simple visual breakdown of Shallow vs Deep Copy. #Java #LearningEveryday #SoftwareDevelopment #Coding

Day 24 of #50DaysOfCode – Java 💻 Today’s challenge was to check whether a number is an Automorphic Number. An Automorphic Number is a number whose square ends with the same digits as the number itself. Examples: 5 → 25 ✔️ (ends with 5) 76 → 5776 ✔️ (ends with 76) This problem helped me understand digit comparison, modulus operations, and number patterns in Java 🔍✨ #Java #CodingChallenge #50DaysOfCode #LearnToCode #ProgrammingBasics #LogicBuilding #CodeDaily #ProblemSolving #AutomorphicNumber #JavaBeginner

Why does 1 == 1 return true but 128 == 128 return false in Java? 🤔 Last week, I stumbled across this little Java “paradox” again — and it reminded me how deep even the simplest lines of code can go. I broke it down in my latest article — explaining what really happens under the hood with Integer caching and autoboxing. 👉 Check it out here: https://lnkd.in/ef2Zxadr #Java #Programming #Coding #SoftwareEngineering #JavaInternals

Today I worked on a small but very interesting problem in Java: reversing the words in a sentence. For example: Input: "I love Java" Output: "Java love I" Here’s a clean approach using split() Key Points: trim() removes leading and trailing spaces split("\\s+") handles multiple spaces between words This simple program is a great example of using Java’s string handling and array manipulation. Try it out and see how easy it is to reverse words in any sentence! #Java #Programming #Coding #DSA #ProblemSolving

🚀 Exploring Abstraction in Java! Today, I practiced one of the key OOP concepts — Abstraction using an example program in Java. In this program, I created an abstract class Shape and implemented different subclasses like Square, Rectangle, and Circle, each providing its own logic for calculating the area. ✨ Key Concepts Covered: Abstract classes and methods Method overriding Dynamic method dispatch Code reusability and clarity through abstraction 🧠 Output: The program accepts input for each shape and displays the calculated area dynamically. Learning abstraction helped me understand how we can hide implementation details and focus only on essential functionalities. 💻 #Java #OOPs #Abstraction #LearningByCoding #ProgrammingJourney #CodePractice

Day 23 of #50DaysOfCode – Java 💻 Today’s challenge was to check whether a number is a Perfect Number. A Perfect Number is a number that is equal to the sum of all its positive divisors (excluding itself). Example: 6 → 1 + 2 + 3 = 6 28 → 1 + 2 + 4 + 7 + 14 = 28 This problem helped me strengthen my understanding of loops, conditions, and mathematical logic 🔍✨ #Java #CodingChallenge #50DaysOfCode #LearnToCode #ProgrammingBasics #LogicBuilding #CodeDaily #ProblemSolving
