CSC 212 -- Project Proj4

• Goal: Write a query system for determine all of the flights between two airports.

• Input: flights.txt

• Log: Keep a log of the compile-time and runtime errors that you found and fixed in your code. If it is a runtime error, explain how you located the error. This will count for 10% of the grade for this project. You don't have to include trivial errors, only the ones that were harder to find, understand and fix.

• Grading of Source Code: Functionality: 50%; Indentation: 10%; Comments: 10%; Header containing name, project name and submission date: 5%; Project name and your name in zip file name, for example, proj4-smith.zip: 5%; input file: 10%; Well-written: 10%.

  Submissions that do not compile can receive as much as a 50% deduction.

• Overall Grading: Source code: 80%; UML diagram: 10%; Debugging log: 10%.

• Details:
  1. Construct the UML diagram for a Flight class that contains these private instance variables:

     Variable Name	Meaning
     orig	Airport of Origin
     dest	Airport of Destination
     day	Day of Flight Departure
     depart	Departure Time
     arrive	Arrival Time
     price	Price of Flight

     Include these methods: parameterized constructor, getters for all instance variables, a setter for price and a toString method. Also include a main method within the Flight class that tests all of the methods.

     Note:   This class is different than the ones we have written until now. The main method is included in the class, rather than placed in a separate test class.

  2. Write the JavaScript code for the Flight class. Run the main method to test your class.

  3. Write a CheckFlights class. It contains one instance variable, which is an array of Flight objects. Here is pseudocode for the main method:

     Instantiate the Flight array.  
         It should hold at least 417 elements.
     Populate the Flight array with data 
         from flights.txt.
     While(true)
         Prompt user to enter airport of origin.
         Input origin to search.
         Prompt user to enter airport of destination.
         Input destination to search.
         Prompt user to enter day of flight.
         Input day to search.
         Print the departure time, arrival time 
             and price for all flights that match 
             the entered criteria.
     End while.
     

     Use control-c to exit the program.

• Sample Output:  

  > javac Flight.java
  > javac CheckFlights.java
  > java CheckFlights
  Enter Airport of Origin: ORD
  Enter Airport of Destination: DFW
  Enter Day of Flight: MON
  
  Departure: 0740  Arrival: 0950  Price: 120.00
  Departure: 1410  Arrival: 1620  Price: 120.00
