Question 1 1 pts This code (from the textbook) creates a Queue reference variable, but assigns a LinkedList object to it. Why? Queue waitList = new LinkedList 0); waitList.add("Neumann party of 1"); waitList.add("Amdahl party of 2"); waitList.add("Flynn party of 4"); System.out.println("Serving: " + waitList.remove()); System.out.println("Serving: " + waitList.remove()); System.out.println("Serving: " + waitList.remove()); O Queue is a Java interface and not an implementation. The Java.util.LinkedList.remove() method is used to remove an element from a linked list. The element is removed from the beginning or head of the linked list. The Java.util.LinkedList.add(T object) method is used to append the specified element to the end of this list. O Linked List is a superclass of queue Linked List is a subclass of queue Linked List and Queue are in the same package Question 2 1 pts Which of the following is the output of the below code: import java.util."; public class Queue Samples public static void main(String[] args) { Queue cities= new LinkedList0; cities.add("Charlotte"); cities.add("Miami"); cities.add("Washington DC"); cities.add("Atlanta"); System.out.println(cities.remove(): Charlotte O Miami Washington DC O Atlanta
