Ticket Booking System with ReentrantLock

$$ Create a program that simulates a theater ticket booking system where multiple

users $($threads$)$ try to book seats simultaneously.

$$ The Theater class should represent the seating arrangement and have methods for

booking seats. Use reentrant locks to ensure that a seat cannot be double$-$booked.

$$ Implement a bookSeat$($int seatNumber$)$ method in the Theater class that marks

a specific seat as booked. If the seat is already booked, the method should print

a message indicating that the seat is unavailable. Use reentrant locks to prevent

multiple threads from booking the same seat simultaneously.

$$ Add a feature where, if a seat is unavailable, the thread is added to a waiting list

$($simulated with a queue$).$ If the seat becomes available, the first thread in the

waiting list should be notified.

$$ Add a timeout feature where a thread attempts to book a seat only for a limited

amount of time. If it cannot acquire the lock within the timeout, it should cancel

the booking attempt
