need help on this. Thanks in advance! Page 2secondary, with a single queue associated with each set. Customers arrive inthe system and are served first by a primary server and, on completion of thisservice, by a secondary server. If all servers of a particular type are busy, thecustomer will enter either the primary or secondary queue as appropriate.The simulation should be run until the last customer has left the system.Output, to standard output, for each version of the queuing process will consistof the following data:• Number of people served.Time last service request is completed.• Average total service time.•Average total time in queue(s). Both overall and separate.Average length of queue. For each queue and overall.•Maximum Length of queue. For each queue and overall.• Total idle time for each server.NOTE: Since the question is to assess your understanding of the concept of Queue, youare NOT allowed to use the library of the language that implement queue. You need towrite the codes (implementation) of Queue for this exercise. (See point (iii).)Other requirements:.Software (programming language):o Java Version - JDK 6 update 17 or above (Using Windows)o C++ / C compiler - g++ 4.0 or above (Using Linux)o Python 3.xOperating System:o Windows XP Professional,o Windows Vista Home / Business,o Windows 7,oWindows 10,o Ubuntu Linux 8.04 LTS or above.If you use a different environment, please make sure that you MUST check withyour lecturers first!For C++ solution, students are to give batch / make files for compilation.Students are to place all compilation and instructions on how to run the programinside a readme.txt file. The markers will refer to this file when marking.Programs should be appropriately documented with comments. Part B:Page IYour task for this assignment is to investigate some of the properties of queues.You should write a Java, C++, or Python program which simulates the queuingand service of a set of requests at a fast food restaurant.Input consists of the following data:• The number of primary servers in the system.• The number of secondary servers in the system.• A set of service requests each consisting of an arrival time and two servicetimes. This set is terminated by a dummy record with arrival time and servicetimes all equal to 0. (Note: the arrival times are sorted in ascending order).For example, the data file:321 2 3335322432524000indicates there are 3 primary servers and 2 secondary servers. The first service(customer) arrives in minute 1 (first minute of simulation), and the service requires2 minutes of primary server's time and 3 minutes of secondary server's time. Thesecond service (customer) arrives in minute 3, and it requires 3 minutes of primaryserver's time and 5 minutes of secondary server's time, etc.The last entry of the data file 0 0 0 indicate the end of simulation. (Note that it ispossible to have two customers arrive in the same time as shown in the abovesample data (second and third customers).)Your program should read the name of the data file from standard input andthen read the data in the named file into the simulation. For example, thefollowing command will trigger the execution of your program by reading thedata file provided:./QueueSim datafile.dat orjava QueueSim datafile.datThe simulation is to be of a system with two sets of servers, primary and
