Project 4 Introduction - The SeaPort Project ... Your question needs more information to be answered. A Chegg Expert needs more info to provide you with the best answer. See comments below. . Question: 1 Project 4 Introduction - the SeaPort Project ser... Edit question 1 Project 4 Introduction - the SeaPort Project series For this set of projects for the course, we wish to simulate some of the aspects of a number of Sea Ports. Here are the classes and their instance variables we wish to define: SeaPortProgram extends JFrame o variables used by the GUI interface o world: World Thing implement Comparable o index: int o name: String o parent: int World extends Thing o ports: ArrayList o time: PortTime SeaPort extends Thing o docks: ArrayList o que: ArrayList // the list of ships waiting to dock o ships: ArrayList // a list of all the ships at this port o persons: ArrayList // people with skills at this port Dock extends Thing o ship: Ship Ship extends Thing o arrivalTime, dockTime: PortTime o draft, length, weight, width: double o jobs: ArrayList PassengerShip extends Ship o numberOfOccupiedRooms: int o numberOfPassengers: int o numberOfRooms: int CargoShip extends Ship o cargoValue: double o cargoVolume: double o cargoWeight: double Person extends Thing o skill: String Job extends Thing - optional till Projects 3 and 4 o duration: double o requirements: ArrayList // should be some of the skills of the persons PortTime o time: int Eventually, in Projects 3 and 4, you will be asked to show the progress of the jobs using JProgressBar's. 2 Here's a very quick overview of all projects: 1. Read a data file, create the internal data structure, create a GUI to display the structure, and let the user search the structure. 2. Sort the structure, use hash maps to create the structure more efficiently. 3. Create a thread for each job, cannot run until a ship has a dock, create a GUI to show the progress of each job. 4. Simulate competing for resources (persons with particular skills) for each job. Project 4 General Objectives Project 4 - Concurrency Resource pools o Threads competing for multiple resources Blocking threads Extending the GUI interface to visualize the resource pools and progress of the various threads. Documentation Requirements: You should start working on a documentation file before you do anything else with these projects, and fill in items as you go along. Leaving the documentation until the project is finished is not a good idea for any number of reasons. The documentation should include the following (graded) elements: Cover page (including name, date, project, your class information) Design o including a UML class diagram o classes, variables and methods: what they mean and why they are there o tied to the requirements of the project User's Guide o how would a user start and run your project o any special features o effective screen shots are welcome, but don't overdo this Test Plan o do this BEFORE you code anything o what do you EXPECT the project to do o justification for various data files, for example Lessons Learned o express yourself here o a way to keep good memories of successes after hard work 3 Project 4 Specific Goals: Extend project 3 to include making jobs wait until people with the resources required by the job are available at the port. Elaboration: 1. Reading Job specifications from a data file and adding the required resources to each Job instance. 2. Resource pools - SeaPort.ArrayList list of persons with particular skills at each port, treated as resource pools, along with supporting assignment to ships and jobs. 3. Job threads - using the resource pools and supporting the concept of blocking until required resources are available before proceeding. 4. The Job threads should be efficient: 1. If the ship is at a dock and all the people with required skills are available, the job should start. 2. Otherwise, the Job should not hold any resources if it cannot progress. 3. Use synchronization to avoid race conditions. 4. Each Job thread should hold any required synchronization locks for a very short period. 5. When a job is over, all the resources used by the job (the people) should be released back to the port. 6. When all the jobs of a ship are done, the ship should depart the dock and if there are any ships in the port que, one of then should should be assigned to the free dock, and that ships jobs can now try to progress. 7. NOTE: If a job can never progress because the port doesn't have enough skills among all the persons at the port, the program should report this and cancel the job. 5. GUI showing: o Resources in pools - how many people with skill are currently available o Thread progress, resources acquired, and resources requests still outstanding Deliverables: 1. Java source code files 2. Data files used to test your program 3. Configuration files used 4. A well-written document including the following sections: a. Design: including a UML class diagram showing the type of the class relationships b. User's Guide: description of how to set up and run your application c. Test Plan: sample input and expected results, and including test data and results, with screen snapshots of some of your test cases d.

Use one of the following formats: MS Word docx or PDF. 4 Your project is due by midnight, EST, on the day of the date posted in the class schedule. We do not recommend staying up all night working on your project - it is so very easy to really mess up a project at the last minute by working when one was overly tired.
