Given that the elements of a PriorityQueue are ordered according
to natural ordering, and:
2. import java.util.*;
3. public class GetInLine {
4. public static void main(String[] args) {
5. PriorityQueue<String> pq = new
PriorityQueue<String>();
6. pq.add("banana");
7. pq.add("pear");
8. pq.add("apple");
9. System.out.println(pq.poll() + " " + pq.peek());
10. }
11. }
What is the result?
Homework Answers
Answer: apple banana
For a priorityqueue interface ,poll() method retrieves the head of the list which is banana; poll() method retrieves tail of the queue which is apple
Hence apple banana is the output.
