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

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

🌟 Main Method in Java The main method is the entry point of every Java program. It allows the OS to hand over control to your code for execution. 📝 Signature: public static void main(String[] args) 💡 public → accessible to OS 💡 static → no object needed 💡 void → no return 💡 String[] args → command-line arguments ✅ Example: class Demo { public static void main(String[] args) { System.out.println("Hello World!"); } } #Java #ProgrammingBasics #Coding #HelloWorld #LearningJourney #ComputerScience

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

💻 Exploring Patterns in Java! Today, I implemented a simple yet classic program — a Hollow Square Pattern using nested loops in Java. This program helps in understanding: ✅ The logic behind nested for-loops ✅ The use of conditional statements for pattern control ✅ How small programs improve logical thinking & coding structure Here’s the output for input 3: *** * * *** Every line of code brings a new learning opportunity. 🔥 #Java #Programming #PatternPrinting #DeveloperJourney #CodingPractice #LogicBuilding #LearnWithCode

🚀 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 7 of #50DaysOfCode – Java Today I practiced arrays and conditional statements by writing a program to find the smallest number from five user inputs. 💻 What I did: Took 5 numbers from the user Stored them in an array Used a loop and if condition to find the smallest number 🧠 Concepts learned: Arrays (int[]) Loops (for) Conditional statements (if) Input/output using Scanner Step by step, getting stronger with Java! 💪 #Java #CodingJourney #LearnInPublic #Programming #50DaysOfCode

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

🔹 The 4 Pillars of Object-Oriented Programming in Java Understanding the core principles of Object-Oriented Programming — Encapsulation, Inheritance, Polymorphism, and Abstraction — is essential for writing clean, reusable, and scalable code in Java. In this post, Otávio Borges breaks down each of these pillars with clear examples to help developers strengthen their object-oriented mindset. 💡 #Java #OOP #ObjectOrientedProgramming #JavaDevelopers #Programming #SoftwareDevelopment #Coding #LearnJava #BrasilJUG #DevsJava

Day 21 of #50DaysOfCode – Java Today’s challenge was Printing All Prime Numbers Between 1 and N. This task helped me understand how to identify prime numbers and how nested loops work in Java. Key learnings from today: 🔹 A prime number is divisible only by 1 and itself 🔹 We can check primality by testing divisibility 🔹 Using logical conditions and loops together improves problem-solving Slowly building confidence with new concepts every day! 💪✨ #Java #CodingJourney #50DaysOfCode #PrimeNumbers #LogicBuilding #ProgrammingBasics #LearningEveryday
