finish up the code below so it runs as so: Customers in a Queue Simulation!

How many service areas? $4$

How long, in minutes, should the simulation run? $60$

Total customers served $=33$

Average wait time $=9\mathrm{.}6$

Longest wait time $=16$

Longest queue $=11$ this is the code so far: import java.util.$*$;

import java.io$.*$;
