Most developers focus only on speed… but memory usage is equally important. This is where Space Complexity comes in. In this short video, I covered: - What is space complexity - Big O notation for memory - O(1), O(n), O(n²) explained - Why recursion uses extra space Understanding both time and space complexity helps you write efficient and scalable code.

Abstraction is one of the core principles of OOP that focuses on hiding implementation details and showing only essential features of an object. In simple terms, abstraction allows you to focus on what an object does instead of how it does it. Why is Abstraction important? Reduces complexity in code Improves readability and maintainability Enhances security by hiding sensitive details Promotes reusability and flexibility How is it implemented in Java? Using abstract classes (partial abstraction) Using interfaces (full abstraction) Example: When you use a mobile phone, you simply make calls or send messages without knowing the internal circuitry. That’s abstraction in action! Mastering abstraction helps developers design scalable and efficient systems. #Java #OOP #Programming #SoftwareDevelopment #CodingConcepts

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

Explored the fourth pillar of Object-Oriented Programming, Abstraction, and applied it by solving a set of focused problems. This helped me understand how abstraction enables hiding implementation details while exposing only the essential functionalities, leading to cleaner architecture and better separation of concerns. Practicing these problems also gave me clarity on using abstract classes and interfaces effectively in Java. Building this foundation is helping me approach problems with a more structured and design-oriented mindset rather than just focusing on implementation.

🔹 Compile-Time vs Runtime Polymorphism Polymorphism is a fundamental concept in Object-Oriented Programming that enables a single interface to represent multiple forms, enhancing code flexibility and reusability. 📌 Compile-Time Polymorphism (Method Overloading) Resolved during compilation, it involves defining multiple methods with the same name but different parameter signatures. • Achieves early binding • Improves readability and structure • Offers better performance due to compile-time resolution 📌 Runtime Polymorphism (Method Overriding) Resolved at runtime, it occurs when a subclass provides a specific implementation of a method defined in its superclass. • Achieves dynamic binding • Enables runtime decision-making • Supports extensibility and scalability 💡 Key Distinction: Compile-time polymorphism is determined by the compiler, whereas runtime polymorphism is resolved during execution through dynamic method dispatch. A strong understanding of both is essential for designing efficient, scalable, and maintainable Java applications. #OOP #SoftwareEngineering #Programming

🚀 Code 6 – #50LeetCodeChallenge 🧩 Problem: Search Insert Position Given a sorted array of distinct integers and a target value, return its index if found. If not, return the position where it should be inserted to maintain sorted order. 💡 Approach: Use Binary Search to efficiently locate the target or its correct insertion position in O(log n) time. 📚 Key Takeaway: Binary search is the go-to technique for problems involving sorted arrays, especially when optimal time complexity is required. #LeetCode #Java #Coding #ProblemSolving #BinarySearch #Arrays #Programming

When coding.... it's always important to give meaningful names to your variables. This improves human readability. So the time I create an array of booleans, I'm going to call it aBunchOfBool. Uhm.... well maybe not. #programming #coding #humor #silly #codingJoke #codingHumor #java #javaProgramming #ProgrammingTips

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

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.
