Hustle & Code – Day 2/25 🔥 OOP in Java + LeetCode Arrays + First API Upgrade

🚀 Day 2 of my 25-Day Coding Challenge is done!
Today I explored OOP concepts in Java (Class, Objects, Methods and constructors), solved LeetCode Array problems (Contains Duplicate & Maximum Subarray), and even created my First Hello world API 🙌.

In this series, I’m documenting my journey of:
✅ Java + DSA preparation for placements
✅ LeetCode problem-solving (Easy to Medium)
✅ Step-by-step Backend Development (Node.js + APIs)
✅ Daily YouTube Shorts & Instagram Reels updates

This challenge is all about building consistency, sharpening problem-solving skills, and leveling up as a developer 💻🔥.

👉 Stay tuned for more — Day 3 drops tomorrow! 🚀
