I am looking to get this project done for a fair price. It must be done in Java and I need it finished by Wednesday November 20th, around 5PM eastern time zone. If you have any questions please feel free to message me privately. Below are the instructions as well as an attached PDF of the project.
This project will familiarize you with the creation and
execution of threads, and with the use of the Thread class methods. In order to
synchronize the threads you will have to use (when necessary), run( ), start( ),
currentThread( ), getName( ), join( ), yield( ), sleep(time), isAlive( ), getPriority( ),
setPriority( ), interrupt( ).
In synchronizing threads, do NOT use any semaphores, wait( ), notify( ) or
Tourists go to Ellis Island to learn about the beginnings
of America, and about their ancestors who immigrated to
Every one and a half hours a documentary movie is
presented. A movie session contains a presentation
period, and the movie. Before the movie session starts,
interested visitors wait in the lobby (use busy waiting).
When the session starts, visitors check if there are
available seats, and if yes, they take one of the
available seats. Checking and updating the number of
available seats represents a critical section and it
should be done from inside of a synchronized method. If
there are no free seats, the visitors leave the room.
They will attempt to attend the next coming movie session
(use busy waiting). They are, a bit, worried that they
might not be able to attend any movie session, so they
rush and check if there are available seats in the next
presentation. In order to do so, they increase their
priority (use getPriority and setPriority). Note: this
should happen for a very short time and after the check,
the priority is reset back to default. If the next
session is already full they give up (use yield() to
simulate give up) and move on in visiting the museum.
Visitors that attend the movie session will next listen
to the speaker’s presentation (busy waiting). After the
watching the movie they will also move on in visiting the
Before the movie starts, a speaker will give a short
introduction to the present audience. When the
presentation ends, everybody watches the movie (sleep of
At the end of the day, when the museum is closing, all
visitors will leave. They will do this in decreasing
order of their name (id) (this must be implemented using
isAlive() and join())
The speaker waits for the time to start the presentation
(by sleeping for a time that is long enough so that it
will be interrupted when times comes. (use interrupt( )
and isInterrupted()). At the end of the day the speaker
In order to keep track of the time, we need an additional
thread, named clock. The clock will signal when a session
starts, when a session ends, and when it is the end of
the day. (This will be implemented by having the clock
sleep for fixed interval of time) Between movie sessions
we should have a break of 15 minutes.
Initial values: theater capacity: 6
Using Java programming, synchronize the three types of threads,
visitor(s), speaker, clock, in the context of the problem.
Closely follow the implementation requirements.
Use appropriate [url removed, login to view]( ) statements and the age( )
method to reflect the time of each particular action done by a
specific thread. This is necessary for us to observe how the
synchronization is working.
