Implementing Diamond Pattern in Java with Loops and Logic

Today I practiced a simple yet important concept of Object-Oriented Programming — Method Overriding. 🔹 Created a parent class (Shape) with a draw() method 🔹 Overrode the same method in child classes Circle and Rectangle 🔹 Demonstrated runtime polymorphism using a parent class reference 💡 This example clearly shows how Java decides which method to call at runtime based on the object type. 📌 Output: Drawing a Circle Drawing a Rectangle ✨ Concepts Covered: ✔ Inheritance ✔ Method Overriding ✔ Runtime Polymorphism #Java #OOP #Programming #Coding #MethodOverriding #Polymorphism #LearningJourney #SoftwareDevelopment #JavaDeveloper

Sum of the Array in Java | Easy Logic + Coding 💡 Strong fundamentals are the key to mastering programming. This example shows how to find the sum of array elements using simple logic: • Start with an array of numbers • Initialize a sum variable to 0 • Traverse the array using a loop • Add each element to the sum • Print the final result Practicing these basic problems helps build strong logical thinking and coding confidence. 📊 Example Input : [1, 2, 3, 4] Output : 10 🎥 I’ve also created a short video explaining this concept with code: YouTube link : https://lnkd.in/g9SJ3hvJ #Java #Programming #ProblemSolving #Coding #SoftwareDevelopment #Learning #CSE #Developers #LogicBuilding #Arrays

🔁To My Java Full Stack Journey Instead of just learning loops, I tried solving real problems 👇 🔹 Rotate a number k times 🔹 Problem Statement: n = 12345, k = 2 Output → 45123 🔹 What I learned: Loops help solve real problems Logic building is important Practice improves thinking #JavaFullStack #CodingJourney #Programming #100DaysOfCode

🚀 Turning a simple Java problem into a learning moment! Today I worked on a small but interesting problem: 👉 Find the absolute difference between a number and its reversed form. Leetcode problem: https://lnkd.in/g3wkXSyg 🔍 What this taught me: How to reverse a number using modulus (%) and division (/) Why storing the original value matters before modifying it How Math.abs() helps ensure the result is always positive 💡 Example: If n = 123 Reversed = 321 Absolute difference = |123 - 321| = 198 Sometimes, even small coding challenges sharpen problem-solving skills and reinforce core programming concepts. #Java #Coding #ProblemSolving #DSA #Programming #SoftwareDevelopment #Developers #CodingJourney #LeetCode

Today I learned about Runtime Polymorphism in Java. Runtime Polymorphism is achieved using method overriding, where a subclass provides its own implementation of a method defined in the parent class. It helps in achieving dynamic behavior, meaning the method call is resolved at runtime instead of compile time. Example: I created an Animal class with a sound() method, and then different animals override it with their own sound. Dog → Barks Cat → Meows This shows how the same method behaves differently based on the object. #Java #Programming #OOP #Learning #CodingJourney

🚀 100 Days Java + DSA Challenge | Day 2 Today’s focus was on strengthening my programming fundamentals by covering: 🔹 Operators in Java (Arithmetic, Relational, Logical, Assignment) 🔹 Conditional Statements (if, if-else, nested if, switch) Understanding how operators work and how decisions are made in code is essential for building strong logic. These concepts are the backbone of problem-solving in Data Structures and Algorithms. 💡 Practiced writing multiple programs using conditions and improved my logical thinking step by step. Consistency is the key — small progress every day leads to big results. #100DaysOfCode #Java #DSA #LearningJourney #Coding #SoftwareDevelopment

Working with Arrays in Java has been a major step in strengthening my programming fundamentals 💻 Arrays are one of the most essential concepts in programming—they help in storing multiple values in a single variable, making data handling more efficient and structured. While practicing, I explored different operations like traversal, searching, sorting, and working with both one-dimensional and two-dimensional arrays. Understanding arrays also improved my problem-solving skills, especially when dealing with real-world scenarios such as matrix operations, finding patterns, and optimizing logic. Concepts like index handling, memory allocation, and nested loops became much clearer through consistent practice. This journey is helping me build a strong foundation for advanced topics like data structures and algorithms 🚀 Consistency + Practice = Improvement #Java #Arrays #Programming #Coding #DeveloperJourney #ProblemSolving #StudentLife #Learning #TechSkills #Consistency

Day 7: Polymorphism After inheritance and method overriding, the next important idea is polymorphism. Polymorphism means one reference can take many forms. In Java, a parent type can hold a child object, and when a method is called, the behavior depends on the actual object behind it. That is what makes OOP more flexible and powerful. The same method call can behave differently in different classes. #Java #OOP #Programming #SoftwareEngineering #ComputerScience #koofkee

How do you solve problems where you need to try every possible combination? This is where Backtracking comes in. In this short video, I explained: - What is backtracking - How it works (try → explore → undo) - Real-world examples like N-Queens and Sudoku - Importance of pruning Backtracking is a powerful approach for solving complex constraint-based problems.

Reversed String in Java | Easy Logic + Coding 💡 Strong fundamentals are essential to become a confident developer. This example shows how String Reversal works using simple logic: • Start with a given string • Traverse the string from last character to first • Use loop or built-in methods • Form the reversed string Practicing these types of problems improves logical thinking and strengthens coding basics. 📊 Example Input : LIVE Output : EVIL 🎥 I’ve also created a short video explaining this concept with code: YouTube link : https://lnkd.in/eKH2JJwa #Java #Programming #ProblemSolving #Coding #SoftwareDevelopment #Learning #CSE #Developers #LogicBuilding #String
