Java Collection, PriorityQueue Exercises: Iterate through all elements in priority queue

Java Collection, PriorityQueue Exercises: Exercise-2 with Solution

Write a Java program to iterate through all elements in priority queue.

Sample Solution:-

Java Code:

import java.util.PriorityQueue;
public class Exercise2 {
  public static void main(String[] args) {
    PriorityQueue<String> pq = new PriorityQueue<String>();  
  pq.add("Red");
  pq.add("Green");
  pq.add("Orange");
  pq.add("White");
  pq.add("Black");
  System.out.println("Elements of the Priority Queue: ");
  // iterate the Priority Queue
  for (String element : pq) {
    System.out.println(element);
    }
 }
}

Sample Output:

Elements of the Priority Queue:                                        
Black                                                                  
Green                                                                  
Orange                                                                 
White

Java: Tips of the Day

Choice between Float and Double:

Data type Bytes used Significant figures (decimal)
Float 4 7
Double 8 15

Double is often preferred over float in software where precision is important because of the following reasons:
Most processors take nearly the same amount of processing time to perform operations on Float and Double. Double offers far more precision in the same amount of computation time.
