Program Requirements • Create a new class called “ThemePark.†Inside it, put your main program. This program will manage and monitor all the theme park rides in the park. ThemePark should extend Thread. • Create a new class called “Amusement.†This class should extend Thread. This class will have the following variables and methods to access them. (Remember to use proper Object-Oriented design in its creation): o A ride type (e.g., “Bumper Cars,†“Rollercoaster,†“Carouselâ€) o A waiting Queue (those waiting in line) o A ride Queue (those actively riding the ride) o A maximum capacity (controls how many people can ride) o A ride duration (how long the ride takes) o A running Boolean (is the ride running? True/false) – initially set to false • Override the run() function inside your “Amusement†class. This function should do the following o Set the “running†state to true o Sleep for x seconds (where x is the ride’s duration) o When finished, set the “running†state to false • Inside ThemePark, instantiate five Amusement objects. Assign each Amusement a type, capacity, and duration. Put the capacity at around 20–60 riders at one time o Create a new Queue called “attendees.†Fill this with unique numbers from 1–1000 o Start each of the Amusement threads. Have ThemePark check every second on the “running†status of each Amusement. If an Amusement is not running, first put all of the riders in the Amusement’s ride Queue into the “attendees†Queue. Put the maximum number of riders from the ride’s waiting Queue into the ride Queue. Finally, take a set number of riders from the “attendees†Queue and place them in the Amusement’s waiting Queue Note: here is a diagram to help you make sense of the flow of riders into the various Queues: • If the user types “END,†stop all of the threads and place the riders back into the attendees Queue. Then exit the program Include appropriate comments throughout your code. Remember to use standard Java naming conventions. Put your name and description of the program in the comments at the top. Submit your ThemePark, Amusement, and all associated project Java and class files, as well as a screenshot of it in operation on your computer. Package all of these in a zip file and name the submission in the format: NAME_COURSE_ASSIGNMENT_DATE.zip Submission is due by 11:59 p.m. ET. • If the user types “END,†stop all of the threads and place the riders back into the attendees Queue. Then exit the program Include appropriate comments throughout your code. Remember to use standard Java naming conventions. Put your name and description of the program in the comments at the top. Submit your ThemePark, Amusement, and all associated project Java and class files, as well as a screenshot of it in operation on your computer.

Paper For Above instruction

The task involves designing a multi-threaded simulation of an amusement park's ride management system using Java. The primary goal is to create classes that mimic the operation of rides, queues of visitors, and the overarching theme park controller, demonstrating principles of object-oriented programming, concurrency, and thread management.

At the core of this simulation is the "ThemePark" class that extends Thread. It functions as the central controller, monitoring and coordinating multiple ride instances and overseeing visitor flow. The "Amusement" class models individual rides, also extending Thread, encapsulating properties such as ride type, capacity, ride duration, and operational state. Each amusement ride has its own waiting queue for visitors waiting to board and a ride queue for those actively participating in the ride.

The simulation begins with instantiating five Amusement objects within the ThemePark class, each assigned specific attributes such as type, capacity, and duration. An "attendees" queue is initialized with unique identifiers from 1 to 1000, representing individual visitors. The main ThemePark thread then starts each amusement thread.

In the core loop, the ThemePark thread checks every second whether each ride is running. If a ride is not active, the system returns riders from its ride queue back to the main attendees queue, signifying the end of the ride cycle. It then transfers riders from the waiting queue into the ride queue, up to the ride's maximum capacity, simulating boarding. Next, a certain number of visitors from the attendees queue are moved into each ride's waiting queue, representing new visitors waiting their turn.

This cycle continues, simulating the ongoing operation of the amusement park rides. The user can input "END" at any point to halt the simulation, at which stage all active riders are returned to the attendees queue, and all threads are safely terminated.

Proper synchronization mechanisms (e.g., synchronized blocks, wait/notify) are essential to prevent race conditions when multiple threads access shared queues. Comments and Java naming conventions should be used extensively for clarity and maintainability.

In summary, this program demonstrates how multi-threaded programming can be used to realistically model complex, concurrent systems such as amusement park operations, emphasizing thread control, resource sharing, and graceful shutdown procedures.
