Implement a method concatenate in class LinkedQueue. This method should take all the elements of a queue sourceQ and append them to the end of another queue targetQ. The operation should result in sourceQ being an empty queue. Test this method in the main method of LinkedQueue.

public class LinkedQueue implements Queue $\{$

$/**$ The primary storage for elements of the queue $*/$

private SinglyLinkedList list $=$ new SinglyLinkedList$<>()$; $//$ an empty list

$/**$ Constructs an initially empty queue. $*/$

public LinkedQueue$()\{\}//$ new queue relies on the initially empty list

$/**$

$*$ Returns the number of elements in the queue.

$*$ @return number of elements in the queue

$*/$

@Override

public int size$()\{$ return list.size$()$; $\}$

$/**$

$*$ Tests whether the queue is empty.

$*$ @return true if the queue is empty, false otherwise

$*/$

@Override

public boolean isEmpty$()\{$ return list.isEmpty$()$; $\}$

$/**$

$*$ Inserts an element at the rear of the queue.

$*$ @param element the element to be inserted

$*/$

@Override

public void enqueue$($E element$)\{$ list.addLast$($element$)$; $\}$

$/**$

$*$ Returns, but does not remove, the first element of the queue.

$*$ @return the first element of the queue $($or null if empty$)$

$*/$

@Override

public E first$()\{$ return list.first$()$; $\}$

$/**$

$*$ Removes and returns the first element of the queue.

$*$ @return element removed $($or null if empty$)$

$*/$

@Override

public E dequeue$()\{$ return list.removeFirst$()$; $\}$

$/**$ Produces a string representation of the contents of the queue.

$*($from front to back$).$ This exists for debugging purposes only.
