<?php // Example of using PriorityQueue in Java import java.util.PriorityQueue; import java.util.Comparator; public class PriorityQueueExample { public static void main(String[] args) { // Creating a PriorityQueue with a custom comparator PriorityQueue queue = new PriorityQueue<>(Comparator.reverseOrder()); // Adding elements queue.add(10); queue.add(20); queue.add(15); // Incorrectly expecting the smallest element System.out.println("Head of the queue: " + queue.peek()); // Outputs 20 // Removing elements while (!queue.isEmpty()) { System.out.println(queue.poll()); } } } ?>
