Please help, i've asked this several times, but the codes couldn't run. If possible, please give give codes in java/python. C++ also possible but need it to be able to run. TIA. Theres a txt file of data given. Below :

secondary, with a single queue associated with each set. Customers arrive in
the system and are served first by a primary server and, on completion of this
service, by a secondary server. If all servers of a particular type are busy, the
customer 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 consist
of 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, you
are NOT allowed to use the library of the language that implement queue. You need to
write 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.x
Operating System:
o Windows XP Professional,
o Windows Vista Home / Business,
o Windows 7,
o
Windows 10,
o Ubuntu Linux 8.04 LTS or above.
If you use a different environment, please make sure that you MUST check with
your 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 program
inside a readme.txt file. The markers will refer to this file when marking.
Programs should be appropriately documented with comments.

Your 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 queuing
and 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 service
times. This set is terminated by a dummy record with arrival time and service
times all equal to 0. (Note: the arrival times are sorted in ascending order).
For example, the data file:
32
1 2 3
335
322
432
524
000
indicates there are 3 primary servers and 2 secondary servers. The first service
(customer) arrives in minute 1 (first minute of simulation), and the service requires
2 minutes of primary server's time and 3 minutes of secondary server's time. The
second service (customer) arrives in minute 3, and it requires 3 minutes of primary
server'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 is
possible to have two customers arrive in the same time as shown in the above
sample data (second and third customers).)
Your program should read the name of the data file from standard input and
then read the data in the named file into the simulation. For example, the
following command will trigger the execution of your program by reading the
data file provided:
./QueueSim datafile.dat or
java QueueSim datafile.dat
The simulation is to be of a system with two sets of servers, primary and
