min heap java implementation code example

Example 1: max heap java

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()+" ");
        }
    }

}

Example 2: use Java NetBeans to write code to implement the list [5, 3, 17, 10, 84, 19, 6, 22, 9] in a Max Heap data structure. For each parent node, display the left and right child of the node.

The Max Heap is 
 PARENT : 52 LEFT CHILD : 21 RIGHT CHILD :23
 PARENT : 21 LEFT CHILD : 15 RIGHT CHILD :13
 PARENT : 23 LEFT CHILD : 7 RIGHT CHILD :16
 PARENT : 15 LEFT CHILD : 5 RIGHT CHILD :9
The max val is 52
