How to Use Jagged Arrays in Java for Irregular Data

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 9 of #50DaysOfCode – Java Today I practiced loops and arithmetic operations by writing a program to find the factorial of a given number. 💻 What I did: Took a number as input from the user Used a for loop to multiply numbers from 1 to n Displayed the factorial result 🧠 Concepts learned: Loops (for) Multiplication operations (*) Input/output using Scanner Step-by-step progress in Java! 💪 #Java #CodingJourney #LearnInPublic #Programming #50DaysOfCode

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 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

🔍 Java Insight of the Day -18: Method Overloading Today I explored Method Overloading, a key concept in Java that enables compile-time polymorphism. It allows multiple methods with the same name but different parameters—making code more readable and flexible. 💡 The Java compiler decides which method to invoke based on: • Method name • Number and type of parameters • Implicit type casting (type promotion) Also discovered that even the main() method can be overloaded—though only the standard signature is executed at runtime. #Java #MethodOverloading #OOP #CompileTimePolymorphism #TechLearning #WomenWhoCode #TapAcademy #100DaysOfCode #JavaDeveloper #CodingJourney #LinkedInLearning

🚀 *Learning Update: Java Arrays & Strings* This week, I explored *Arrays* and *Strings* in Java! 🌟 ✅ *Arrays*: Learned how to store multiple values of the same type in a single data structure, access elements using indices, iterate using loops, and perform common operations like sorting, searching, and updating values. ✅ *Strings*: Practiced handling text data, using methods like `length()`, `charAt()`, `substring()`, `concat()`, `replace()`, and `split()`. I also explored string immutability and how to manipulate strings efficiently. #Java #Programming #Coding #LearningJourney #Arrays #Strings #SoftwareDevelopment

💻 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

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

💻 Did you know you can print output in Java without a main() method? Here’s how 👇 class WithoutMain { static int variable = 10; static { System.out.println(variable); System.exit(0); } } 🧠 Explanation: • When the JVM loads the class, all static blocks execute automatically — even before checking for the main() method. • The System.exit(0); line stops execution before the JVM looks for main(), preventing the usual “main method not found” error. ✅ Output: 10 This is a fun trick to understand how class loading and static blocks work in Java. Not practical for production — but a great interview or concept question! 😉 #Java #Programming #LearnWithHarsh #CodingFacts #JVM #TechLearning

🌟 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
