8.) Priority Queue (basic)

 Write a programe to search for a element in a priority queue.

import java.util.*;

public class PriorityQueueSearch {

    public static void main(String[] args) {

        // Create a priority queue and add some elements

        PriorityQueue<Integer> pq = new PriorityQueue<Integer>();

        pq.add(3);

        pq.add(1);

        pq.add(5);

        pq.add(2);

        pq.add(4);

        // Print the priority queue

        System.out.println("Priority Queue: " + pq);

        // Search for an element in the priority queue

        int searchElement = 2;

        boolean found = pq.contains(searchElement);

        // Print the search result

        if (found) {

            System.out.println(searchElement + " is present in the priority queue.");

        } else {

            System.out.println(searchElement + " is not present in the priority queue.");

        }

    }

}
