Just dropped a new video on Comparator Interface in Java — covering custom sorting logic using multiple approaches (class, anonymous class and lambda). A clean, visual explanation to make sorting truly click. #Java #Comparator #Coding #LearningEveryday Watch here: https://lnkd.in/geW_UKh9

Many developers ask: Why do Java Collections not support primitive data types? The reason is that Java Collections work with objects, not primitives. To handle primitive values, Java uses Wrapper Classes like Integer, Double, and Character. Example: int → Integer double → Double char → Character This process is called Autoboxing and Unboxing. Understanding such small concepts can make a big difference in mastering Java. 🚀 #CoreJava #JavaTips #Programming #JavaDeveloper

Day 62 of #100DaysOfLeetCode 💻✅ Solved #219. Contains Duplicate II problem in Java. Approach: • Used two nested loops to compare elements within range k • For each element, checked next k elements • If any duplicate is found within distance k, returned true • If no such pair exists, returned false Key Learning: ✓ Practiced checking duplicates within a given range ✓ Strengthened understanding of array traversal with conditions ✓ Learned the importance of optimizing nested loop solutions Learning one problem every single day 🚀 #Java #LeetCode #DSA #Arrays #ProblemSolving #CodingJourney #100DaysOfCode

#Day17 – Understanding Constructors in Java ⚙️ Today’s session helped me understand how constructors work in Java and how they are used while creating objects. Key Learnings: ✔ A Constructor is a special type of method whose name is the same as the class name ✔ Constructors do not have any return type, not even void ✔ Constructors are automatically called when an object is created using the new keyword ✔ If a programmer does not create any constructor, Java Compiler provides a Default Constructor ✔ Learned about Parameterized Constructors and Zero-Parameterized Constructors ✔ Understood Constructor Overloading (multiple constructors with same name but different parameters) ✔ Explored Constructor Chaining using this(), where one constructor calls another constructor within the same class TAP Academy Harshit T #Java #OOPS #CoreJava #Constructors #Programming #SoftwareDevelopment #LearningJourney #Consistency

📚 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

Leetcode Problem || Complement of Base 10 Integer(1009) 🚀 The Bitwise Complement problem using Java. 🔹 Idea: The complement of a number means flipping all bits in its binary representation (0 → 1 and 1 → 0). Instead of manually converting the number to binary, I used a bit manipulation trick: 1️⃣ Find the highest set bit using Integer.highestOneBit(n) 2️⃣ Create a mask with all bits set to 1 up to that position 3️⃣ Use XOR (^) with the mask to flip the bits #LeetCode #Java #BitManipulation #CodingPractice #ProblemSolving #SoftwareDevelopment

Day 9 – Java Streams Practice Series Today, I worked on finding the first repeated character in a string using Java Streams. Approach: Converted the string into a stream of characters Used Collectors.groupingBy() with LinkedHashMap to preserve insertion order Counted occurrences of each character Filtered characters with frequency greater than 1 Retrieved the first repeated character using findFirst() Key Learning: Using LinkedHashMap is important because it maintains the order of elements, which helps in identifying the first repeated character correctly. Why this matters: This problem helps strengthen concepts like stream transformations, grouping, counting, and order preservation in collections. Consistent practice is helping me build a deeper understanding of Java Streams and problem-solving. #Java #JavaStreams #CodingPractice #DataStructures #ProblemSolving #BackendDevelopment #100DaysOfCode

✅ DSA Day 8 / 100 Solved Reverse an Array on HackerRank using Java. Problem: Given an array, return the array in reverse order. Logic : - Use the built-in method Collections.reverse() -This method reverses the elements of the list directly -Then return the reversed list This problem helped me understand how arrays/lists can be manipulated easily using Java utility methods. #DSA #100DaysOfCode #Java #HackerRank #LearningInPublic #BeginnerDSA

🚦 Built a Traffic Light Simulation using Java Threads! I recently worked on a project where I implemented a traffic light system using multithreading concepts in Java. Each signal runs as an independent thread, simulating real-world traffic flow. 💡 Key Highlights: Used ThreadPool for efficient thread management Simulated real-time signal switching (Red → Yellow → Green) Extended the project to visualize signals on a webpage Focused on understanding concurrency from scratch (no shortcuts!) 🛠️ Tech Stack: Java | Multithreading | (Optional: HTML/CSS/JS for visualization) This project helped me deeply understand how threads work and how real-world systems like traffic control can be modeled programmatically. Would love your feedback or suggestions to improve it further! #Java #Multithreading #DSA #BackendDevelopment #Projects #LearningInPublic
