Draw a UML class diagram for the following code:
import java.util.*;
public class QueueOperationsDemo {
public static void main(String[] args) {
Queue<String> linkedListQueue = new LinkedList<>();
linkedListQueue.add("Apple");
linkedListQueue.add("Banana");
linkedListQueue.add("Cherry");
System.out.println("Is linkedListQueue empty? " + linkedListQueue.isEmpty());
System.out.println("Front element: " + linkedListQueue.peek());
System.out.println("Removed element: " + linkedListQueue.remove());
System.out.println("Front element after removal: " + linkedListQueue.peek());
Queue<Integer> arrayDequeQueue = new ArrayDeque<>();
arrayDequeQueue.add(10);
arrayDequeQueue.add(20);
arrayDequeQueue.add(30);
System.out.println("Is arrayDequeQueue empty? " + arrayDequeQueue.isEmpty());
System.out.println("Front element: " + arrayDequeQueue.peek());
System.out.println("Removed element: " + arrayDequeQueue.remove());
System.out.println("Front element after removal: " + arrayDequeQueue.peek());
Queue<Double> priorityQueue = new PriorityQueue<>();
priorityQueue.add(5.5);
priorityQueue.add(3.3);
priorityQueue.add(7.7);
System.out.println("Is priorityQueue empty? " + priorityQueue.isEmpty());
System.out.println("Front element: " + priorityQueue.peek());
System.out.println("Removed element: " + priorityQueue.remove());
System.out.println("Front element after removal: " + priorityQueue.peek());

- Simple JAVA linkedlist code implementation please help and complete any part you can - Without using the java collections interface (ie do not import java.util.List,LinkedList, Stack, Queue...)- Create an implementation of LinkedList interface- For the implementation create a tester to verify the implementation of thatdata structure performs as expected Build Bus Route – Linked List- Your task is to:o Implement the LinkedList interface (fill out the implementation shell)o Put your implementation through its paces by exercising each of themethods in the test harnesso Create a client (a class with a main) ‘BusClient’ which builds a busroute by performing the following operations on your linked list:o§ Create (insert) 4 stations§ List the stations§ Check if a station is in the list (print result)• Check for a station that exists, and onethat doesn’t§ Remove a station§ List the stations§ Add a station before another station§ List the stations§ Add a station after another station§ Print the...arrow_forwardJava: Which of the following operations has the least running time in a Queue (assume that only Queue interface operations are available; some operations may require use of an additional temporary queue)? Multiple choice. Deleting the element at the rear of the queue Checking if an element x is present in the queue Finding the number of elements in the queue all of the above have identical worst case running timearrow_forwardIn C++,arrow_forward
