public static void main(String[], args) throws FileNotFoundExcepti.pdf

public static void main(String[], args) throws FileNotFoundException should be your main
method to deal with the possibility that the file is not found. It can have any name. Please also
see pages 478-480 of Liang's 10th Edition.
http://docs.oracle.com/javase/7/docs/api/java/io/FileNotFoundException.html BE SURE AND
PUT YOUR NAME IN A COMMENT AT THE TOP OF YOUR CODE. The program that you
turn in will always be in a single file named unfid.java where unfid is YOUR unf id. So , I
would name my file n00009873.java . This implies that the name of the class containing main
must be n00009873. So , in general, my class containing main will be named n00009873 and
the file containing all my classes will be named n00009873.java Design classes vehicle, car,
american_car, foreign_car, truck, and bicycle with ALL appropriate inheritances. vehicle is the
parent because everything is a vehicle or a member of a descendant of vehicle. The design of
the classes is VERY important. Each of these classes will be in the file with your nnumber class
that has the main() method. DESIGN, DESIGN, DESIGN. Your code must override the
toString method in each class to display ALL the relevant information from the record. Also
design an application class (your nnumber class with a main) that tests your classes and
processes a file of records. The file of data to be used will be constructed by me with the
following format used (examples are here): I WILL USE NOTEPAD TO CONSTRUCT THE
FILE. TEST WITH A FILE FROM NOTEPAD. vehicle owner's name (string) address (string)
phone (string) email (string) car owner's name (string) address (string) phone (string) email
(string) true or false for convertible (boolean) color (string) american car owner's name (string)
address (string) phone (string) email (string) true or false for convertible (boolean) color (string)
true or false for made in Detroit (boolean) true or false for union shop (boolean) foreign car
owner's name (string) address (string) phone (string) email (string) true or false for convertible
(boolean) color (string) country of manufacturer (string) import duty (float) bicycle owner's
name (string) address (string) phone (string) email (string) # of speeds (int) truck owner's name
(string) address (string) phone (string) email (string) # of tons (float) cost of truck (float) date
purchased (format below in exmample) etc.....these records can appear in any order and there
can be up to 200 of them. Records will have a blank line between them. You will need to use an
array of vehicle to store the data. Here are some examples of data: foreign car aMarioy

class (your nnumber with a main) that reads a file (from the command line) and fills an array of
type vehicle[] with new vehicle (params), new car (params), new american car (params) new
foreign car(params) , new truck (params), new bicycle (params), etc.: the params depend on the
first line that identifies each record. params is just a shorthand name for parameter list (the
arguments to a method.) To get the file , in jGrasp you must click on the tab file/check run args,
and then type the name of the file in the box at the top. I will test your program with my own
file! You must not type in the name of the file in your code because it is only specified at run
time. The name of the file in your code will be args[0] when you use public static void
main(String[], args) throws FileNotFoundException . Because the input comes from the file
instead of the keyboard you should be able to modify Scanner to deal with wrapping! Scanner x
= new Scanner(new File(args[0])). Google "java scanner" to learn about Scanner and/or "java
command line" to learn about args[0]. This information is located on pages 478-480 of Liang's
10th Edition. Print the output from each of the following calls: 1. Call a printAll method
that can be passed an array of type vehicle[] and which prints each element of the array
using the appropriate toString() methods. ArrayList is fine if you wish to use it. 2. Call a
sort method that can be passed an array of type vehicle[] and which sorts the array by email
addresses and prints the new sorted array using appropriate toString() methods. Any sort
method is fine, but it should sort according to unicode (case sensitive, that is to say that
all upper case is before any lower case)! 3. Call a method that prints the number of
records. 4. Call a method that prints just the bicycles and trucks (from the sorted array
using the appropriate toString() methods). 5. Call a method that prints the vehicles in area
code 987. THERE ARE NO PROMPTS. JUST RUN THE PROGRAM. Be sure to declare
variables as private, to extend all the classes appropriately, and to have the right constructors
(using super where appropriate), and the getters and setters for ALL the variables. MUST SEND
ALL THE OUTPUT FROM PRINTING TO THE CONSOLE, NOT TO A WINDOW.
