Revise the Average Waiting Time program to do the following:

a) Also output the largest number of customers who were on a queue at the same time.

b) Choose the queue for a customer to enter based on shortest finish time, rather than shortest size. The user should have the ability to choose which approach to use for any simulation run.

{

void enqueue(T element);

//Adds element to the rear of this quee.

{

T dequeue() throws QueueUnderflowException;

//Throws QueueUnderflowException if this queue is empty;

//otherwise, removes front element from this queue and returns it

boolean isEmpty();

//Returns true if this queue is empty; otherwise, return false
