java heap example

import java.util.PriorityQueue; public class MaxHeapWithPriorityQueue { public static void main(String args[]) { // create priority queue PriorityQueue<Integer> prq = new PriorityQueue<>(Comparator.reverseOrder()); // insert values in the queue prq.add(6); prq.add(9); prq.add(5); prq.add(64); prq.add(6); //print values while (!prq.isEmpty()) { System.out.print(prq.poll()+" "); } } }

min max heap java

// min heap: PriorityQueue implementation from the JDK
PriorityQueue<Integer> prq = new PriorityQueue<>();

// max heap: PriorityQueue implementation WITH CUSTOM COMPARATOR PASSED
// Method 1: Using Collections (recommended)
PriorityQueue<Integer> prq = new PriorityQueue<>(Collections.reverseOrder());
// Method 2: Using Lambda function (may cause Integer Overflow)
PriorityQueue<Integer> prq = new PriorityQueue<>((a, b) -> b - a);
