Java Collection, PriorityQueue Exercises: Exercise-7 with Solution

Write a Java program to compare two priority queues.

Sample Solution:-

Java Code:

import java.util.PriorityQueue;
  public class Exercise7 {
  public static void main(String[] args) {
  // Create a empty Priority Queue
        PriorityQueue<String> pq1 = new PriorityQueue<String>();  
     // use add() method to add values in the Priority Queue
          pq1.add("Red");
          pq1.add("Green");
          pq1.add("Black");
          pq1.add("White");
          System.out.println("First Priority Queue: "+pq1);
          PriorityQueue<String> pq2 = new PriorityQueue<String>();  
          pq2.add("Red");
          pq2.add("Pink");
          pq2.add("Black");
          pq2.add("Orange");
          System.out.println("Second Priority Queue: "+pq2);
          //comparison output in Priority Queue
         for (String element : pq1){
             System.out.println(pq2.contains(element) ? "Yes" : "No");
          }      
     }
}

Sample Output:

First Priority Queue: [Black, Red, Green, White]                       
Second Priority Queue: [Black, Orange, Pink, Red]                      
Yes                                                                    
Yes                                                                    
No                                                                     
No
