How many vehicles do you want to create?

INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

Description

Assignment 2 will extend the midterm – please use the sample solution for the midterm as your starting point. Instead of having the available vehicles hard-coded in the source code, at program startup, the user should be given two choices: 1) to enter the available vehicles, or 2) to load the available vehicles from a file. If the user chooses option 1, the program should prompt the user for the number of vehicles to enter, and then allow the user to enter the details of the chosen number of vehicles. The program should then create a Vehicle array with the entered values and store the content of that array into a file called NewVehicles.txt. If the user chooses option 2, they program should ask for a file name, and then load the vehicles from that file and insert them into a Vehicle array. Now, irrespective of which choice the user made, the program should continue as before, by displaying the choice of vehicles from the array and allowing the user to create a rental.

Required File Format

 

The file to store vehicles must have the following structure: The first line contains the number of vehicles. After this, for each vehicle, the first line indicates the type of vehicle (Car or Truck), followed by lines for the model, the rate and finally the size or cargo capacity (depending on

 

whether it is a car or a truck). In other words, for each vehicle, the file should contain four lines. The following is an example of a file with three vehicles – a car followed by a truck followed by another car:

3

Car

Toyota Yaris 50.0 COMPACT

Truck Ford F150 120.0

8500.0

Car

BMW 750i 199.0 PREMIUM

 

The file to store to or load from should be located in the src folder of your Eclipse project. To access a file in that folder, use a relative path, similar to the following code example:

Path file = Paths.get("src\\" + fileName);
