Week 13 i) In Chapter 11, you created an interactive RentalDemo class that obtains all the data for four rentals from Sammy's Seashore Rentals, including details about the contract number, length of the rental, and equipment type. Now, modify the class so that it becomes immune to user data entry errors by handling exceptions for each numeric entry. Each time the program requires numeric data—for example, for the rental period—continuously prompt the user until the data entered is the correct type. Save the revised program as RentalDemo.java. Create a zip file of the .java file(s) and submit the assignment. ii) a. In Chapter 12, you created an interactive RentalDemo class that obtains all the data for four rentals from Sammy's Seashore Rentals, including details about the contract number, length of the rental, and equipment type. Now, modify the program to create a data file that contains each contract number, rental time in hours and minutes, equipment type code and name, and price. Save the program as RentalDemoAndCreateFile.java. b. Write a program that displays the data saved in the file created in part 2a. Save the program as DisplayRentalFile.java. Create a zip file of the .java file(s) and submit the assignment. Week 14 i) In previous chapters, you have created a number of programs for Carly's Catering. Now, create an interactive GUI program that allows the user to enter the number of guests for an event into a text field; if the value entered is not numeric, set the event price to 0. Also allow the user to choose one entree from a group of at least four choices, up to two side dishes from a group of at least four choices, and one dessert from a group of at least three choices. Display the cost of the event as $35 per person; as the user continues to make selection changes, display a list of the current items chosen. If a user attempts to choose more than two side dishes, remove all the current side dish selections so that the user can start over. Save the program as JCarlysCatering.java. Create a zip file of the .java file(s) and submit the assignment. ii) . In previous chapters, you have created a number of programs for Sammy's Seashore Rentals. Now, create an interactive GUI program that allows the user to enter a rental time in hours into a text field; if the value entered is not numeric, set the rental price to 0. Also allow the user to choose one equipment type to rent from a group of seven choices. The rental fee is $40 per hour for a personal watercraft or pontoon boat; $20 per hour for a rowboat, canoe, or kayak; and $7 per hour for a beach chair or umbrella. Let the user add an equipment lesson for an extra $5. Display a message that indicates all the details for the rental, including the total price. Save the program as JSammysSeashore.java. Create a zip file of the .java file(s) and submit the assignment.

The administrators of Tiny College are so pleased with your design and implementation of their student registration and tracking system that they want you to expand the design to include the database for their motor vehicle pool. A brief description of operations follows:Faculty members may use the vehicles owned by Tiny College for officially sanctioned travel. For example, the vehicles may be used by faculty members to travel to off-campus learning centers, to travel to locations at which research papers are presented, to transport students to officially sanctioned locations, and to travel for public service purposes. The vehicles used for such purposes are managed by Tiny College’s Travel Far But Slowly (TFBS) Center.Using reservation forms, each department can reserve vehicles for its faculty, who are responsible for filling out the appropriate trip completion form at the end of a trip. The reservation form includes the expected departure date, vehicle type required, destination, and name of the authorized faculty member. The faculty member who picks up a vehicle must sign a checkout form to log out the vehicle and pick up a trip completion form. (The TFBS employee who releases the vehicle for use also signs the checkout form.) The faculty member’s trip completion form includes the faculty member’s identification code, the vehicle’s identification, the odometer readings at the start and end of the trip, maintenance complaints (if any), gallons of fuel purchased (if any), and the Tiny College credit card number used to pay for the fuel. If fuel is purchased, the credit card receipt must be stapled to the trip completion form. Upon receipt of the trip completion form, the faculty member’s department is billed at a mileage rate based on the vehicle type used: sedan, station wagon, panel truck, minivan, or minibus. (Hint: Do not use more entities than are necessary. Remember the difference between attributes and entities!)All vehicle maintenance is performed by TFBS. Each time a vehicle requires maintenance, a maintenance log entry is completed on a prenumbered maintenance log form. The maintenance log form includes the vehicle identification, brief description of the type of maintenance required, initial log entry date, date the maintenance was completed, and name of the mechanic who released the vehicle back into service. (Only mechanics who have an inspection authorization may release a vehicle back into service.)As soon as the log form has been initiated, the log form’s number is transferred to a maintenance detail form; the log form’s number is also forwarded to the parts department manager, who fills out a parts usage form on which the maintenance log number is recorded. The maintenance detail form contains separate lines for each maintenance item performed, for the parts used, and for identification of the mechanic who performed the maintenance. When all maintenance items have been completed, the maintenance detail form is stapled to the maintenance log form, the maintenance log form’s completion date is filled out, and the mechanic who releases the vehicle back into service signs the form. The stapled forms are then filed, to be used later as the source for various maintenance reports.TFBS maintains a parts inventory, including oil, oil filters, air filters, and belts of various types. The parts inventory is checked daily to monitor parts usage and to reorder parts that reach the “minimum quantity on hand” level. To track parts usage, the parts manager requires each mechanic to sign out the parts that are used to perform each vehicle’s maintenance; the parts manager records the maintenance log number under which the part is used.Each month TFBS issues a set of reports. The reports include the mileage driven by vehicle, by department, and by faculty members within a department. In addition, various revenue reports are generated by vehicle and department. A detailed parts usage report is also filed each month. Finally, a vehicle maintenance summary is created each month.Given that brief summary of operations, draw the appropriate (and fully labeled) ERD. Use the Crow’s foot methodology to indicate entities, relationships, connectivities, and participations. You can use either Microsoft Visio or Vertabelo to draw and export the ERD. To upload and submit your assignment, click the submission button below to find and select your saved document. Make sure that the file is saved with your last name in the file name.
