🧰 Heaps in Java Using PriorityQueue | Complete Guide to PriorityQueue Methods
In this video, you’ll learn how to implement and use heaps in Java using the PriorityQueue class — Java’s built-in way to work with min heaps (and how to create max heaps too!). We’ll explore the full range of operations supported by this powerful class.
🔍 What’s Covered:
How Java’s PriorityQueue internally implements a Min Heap
Creating a Max Heap using custom comparators
Adding, removing, and peeking elements
Commonly used methods: add(), poll(), peek(), remove(), offer(), contains()
Real-world use cases of PriorityQueue in coding interviews
Time complexities of operations
Gotchas and best practices for using heaps in Java
Perfect for Java learners, interview prep, and competitive programmers!
