What you'll learn in this thread: ✅ What is a Thread (and the #1 beginner mistake) ✅ Thread Lifecycle — all 5 states explained ✅ Synchronization — volatile vs synchronized vs Lock ✅ Deadlock — how it happens + how to prevent it ✅ Thread Pools — which one to use & when 🎯 A tricky interview question 90% of devs get wrong 💡 Quick tip before you swipe: Never call run() directly. Always use start(). One line. Career-saving advice. 😅 🔁 Repost if this helped someone on your team. 💾 Save this — you'll need it before your next interview. 🔔 Follow for more Java deep-dives every week. #Java #Multithreading #Programming #SoftwareEngineering #JavaDeveloper #BackendDevelopment #CodingTips #TechTwitter #100DaysOfCode #InterviewPrep

Today's Daily DSA Challenge focuses on a fundamental algorithm: Binary Search. What is the time complexity of Binary Search? Feel free to share your answers in the comments.

Here is one the most asked technical interview questions, LeetCode: Longest Substring Without Repeating Characters (medium) Given a string, find the length of the longest substring without repeating characters. 💡 Key idea: Use a sliding window and adjust it whenever a duplicate appears. 🧠 Solution: - Use two pointers to form a window and a hashmap to track character positions. - Move the right pointer through the string. - If a character repeats inside the window, move the left pointer past its last position. - Update the max length at each step. Time Complexity and Space Complexity: O(n) #LeetCode #Algorithms #CodingInterview #SoftwareEngineering #DSA #Java

🚀 Improving DSA one step at a time! Today I solved LeetCode 1446 – Consecutive Characters 🧠 🔍 Problem Insight: Find the longest substring where all characters are the same. 💡 Approach: Traverse the string and keep counting consecutive characters while tracking the maximum. ⚡ Time Complexity: O(n) ⚡ Space Complexity: O(1) 🎥 Full explanation: 👉https://lnkd.in/gbqbVV5Q 🔥 I’m posting daily LeetCode solutions with simple explanations. 👉 Follow me for DSA 👉 Subscribe for full tutorials 💬 Comment “DSA” if you're preparing for interviews! #LeetCode #DSA #Java #Coding #Programming #InterviewPrep #Developers

While preparing for interviews, I revised some important Object-Oriented Programming (OOP) concepts: 🔹 Abstraction Showing only important details and hiding internal implementation 📌 Example: Driving a car without knowing how the engine works internally 🔹 Association A relationship where two classes are connected but can exist independently 📌 Example: Driver and Car 🔹 Composition A strong relationship where one object cannot exist without the other 📌 Example: Car and Engine (if car is destroyed, engine is also gone) 🔹 Aggregation A weak relationship where objects can exist independently 📌 Example: Student and College 💡 These concepts are very important for building strong programming fundamentals and cracking interviews. #OOP #Java #InterviewPreparation #Coding #Learning #Developers #SoftwareTesting #TechSkills
