Stacks & Queues in Java | Linked Lists, Arrays, Generics & Real-World Applications

Discover two of the most fundamental data structures in computer science: Stacks and Queues.

In this tutorial, we explore how to store and manage collections of objects efficiently, implement these structures in Java, and leverage advanced language features like generics and iterators to write clean, reusable code.

🎓 Learning Objectives:

✅ Define and implement stack and queue data types
✅ Use linked lists and resizing arrays for efficient storage
✅ Apply Java generics and iterators for reusable code
✅ Analyze time and space complexity of operations
✅ Explore real-world applications like expression parsing and queue simulations
