Unlock the power of the Priority Queue in Java! ⭐ This isn't your standard FIFO queue. In this tutorial, we explore how a Priority Queue processes elements based on their priority, not just their arrival time.

We'll start with the basics and then dive into the crucial role of the Comparator interface for defining custom ordering.

What you'll learn:

What is a Priority Queue? How is it different from a standard Queue?

Understanding the Min-Heap and Max-Heap behavior.

How to use Natural Ordering (for Integers, Strings, etc.).

The most important part: Custom Comparators for your own objects.

Practical use-cases: Task scheduling, Dijkstra's algorithm, and finding top K elements.

A complete code example from start to finish.

Perfect for intermediate Java learners and a must-know for technical interviews!
