Java Collection, PriorityQueue Exercises: Convert a Priority Queue elements to a string representation

Java Collection, PriorityQueue Exercises: Exercise-11 with Solution

Write a Java program to convert a Priority Queue elements to a string representation.

Sample Solution:-

Java Code:

import java.util.*;
  public class Example11 {
  public static void main(String[] args) {

   // Create 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("Original Priority Queue: "+pq1);
   
   //Convert Priority Queue to a string representation
   String str1;
   str1 = pq1.toString();
   System.out.println("String representation of the Priority Queue: "+str1);    
  }
}

Sample Output:

Original Priority Queue: [Black, Red, Green, White]                    
String representation of the Priority Queue: [Black, Red, Green, White]
