🎯 Introduction to Collections Framework | Java Collections Deep Dive | Coders Arcade

Welcome to Coders Arcade!
In this session, we shift our focus from manual data structure implementation to mastering the Java Collections Framework — an essential toolset for any Java developer. We'll explore the most commonly used interfaces and classes, understand how they work under the hood, and learn when to use what in real-world scenarios.

🚀 What’s Inside:

* 📚 Collections Overview – Understand the need for collections and how they evolved from arrays and linked structures
* 🗂️ Core Interfaces – Explore `List`, `Set`, `Queue`, and `Map` — with practical examples
* 💻 Key Implementations – Hands-on with `ArrayList`, `LinkedList`, `HashSet`, `TreeSet`, `HashMap`, `TreeMap`, `PriorityQueue`
* 🧰 Utility Classes & Algorithms – Using `Collections` and `Arrays` utility classes for sorting, searching, and more
* ⚙️ Use-Cases & Best Practices – When to choose which collection, performance tips, and common pitfalls
