Java == vs equals() in Java Programming

🚀 New Post in my #TechnicalScripter2026 Series! Ever wondered how Java manages strings efficiently? In this post, I explain the concept of the String Pool and how it helps optimise memory and performance. 🔗 Explore the post below. https://lnkd.in/gQnvNaQW #Java #Programming #CodingConcepts

Day 31/100 – Revisiting Java Arrays & Enhanced For Loop ☕ Today I revisited the Enhanced For Loop (for-each loop) in Java while practicing array traversal. Instead of using indexes like a traditional for loop, the enhanced loop lets us directly iterate through each element of the array, making the code cleaner and easier to read. Example idea: for(int num : arr) → goes through each element one by one. Key takeaways: • Cleaner way to traverse arrays and collections • Reduces chances of index-related errors • Makes code more readable and concise Small concepts like these build a stronger programming foundation over time. Still learning. Still consistent. 🚀 #100DaysOfCode #Java #Programming #CodingJourney #SoftwareDevelopment #Consistency #LearningInPublic

📚 Understanding Association in Object-Oriented Programming (OOP) In Java, Association represents a relationship between two classes where objects interact with each other. It is mainly divided into two types: 🔹 Aggregation (Weak Relationship) The secondary object can exist independently of the primary object. Example: A mobile phone and a charger. Even if the phone is lost, the charger can still be used. 🔹 Composition (Strong Relationship) The secondary object is completely dependent on the primary object. Example: A mobile phone and its operating system. If the phone is destroyed, the OS cannot exist separately. Understanding these relationships helps in designing better object-oriented systems with clear structure and maintainability. #Java #OOP #Association #Aggregation #Composition #Programming #SoftwareDevelopment

Turning simple logic into working code 💻✨ Today I worked on a basic yet essential problem in Java—finding the maximum value in an array. It’s one of those foundational exercises that really strengthens your understanding of loops, arrays, and conditionals. 🔹 Took user input using Scanner 🔹 Stored values in an array 🔹 Iterated to find the maximum element What seems simple at first actually builds the backbone of problem-solving skills in programming. Every small step counts in the journey of becoming a better developer 🚀 #Java #CodingJourney #Programming #ProblemSolving #LearningByDoing

Solved “Valid Anagram” problem in Java today 💻 Learned how to efficiently check if two strings are anagrams using: • Sorting approach (clean but O(n log n)) • Frequency array approach (optimized O(n)) 🚀 Key takeaway: Choosing the right approach can significantly improve performance, especially for large inputs. Consistent practice with DSA is helping me strengthen problem-solving skills and think in terms of optimization. #Java #DSA #LeetCode #ProblemSolving #CodingJourney #Programming

How many of you know that this line creates TWO objects? String s1 = new String("Hello"); One object is created in the Heap and another in the String Pool. But things become interesting when we combine concepts like: • Compile-time vs Runtime concatenation • final variables • intern() behavior I’ve added a few tricky Java String questions in this document to test your understanding. Try answering them before checking the explanation. Curious to know — how many did you get right? 👇 #Java #JavaInterview #JavaDevelopers #StringPool #Programming

Day 45-What I Learned In a Day (JAVA) Today I explored some important concepts related to static in Java: 🔹 Static Method Learned how static methods belong to the class and can be called without creating an object. 🔹 Static Initializer (Static Block) Understood how a static block is executed only once when the class is loaded. 🔹 Single-Line Static Initializer Explored how we can initialize static variables in a single line. 🔹 Multi-Line Static Initializer Learned how to use static blocks for complex initialization logic.
