Class TripCity

java.lang.Object
  AmericanCity
      TripCity

public class TripCity
extends AmericanCity

The Trip class is both an executable class and an instantiatable class that each student must further define for HW4. For a complete description, of this assignment go to:

http://www.cs.stonybrook.edu/~cse114/hw/HW4.html


This class runs a program that provides a menu to the user such that they may enter trip information, including the starting city and destination city, as well as the Latitude/Longitude coordinates of those respective cities. This program then prints a trip summary including the trip cities and the trip distance, which should be calculated by a method in this class.

Constructor Summary

TripCity()
Default Constructor for TripCity, when called it initializes both the city name and the state code to NOWHERE and coordinates to 0.

TripCity(java.lang.String initCity, java.lang.String initStateCode, int lat_deg, int lat_min, char lat_dir, int long_deg, int long_min, char long_dir)
Default Constructor for TripCity, when called it initializes both the city name, the state code, and coordinates to the provided parameters

Method Summary

double	calcDistance(TripCity otherCity) Method that returns a Double that represents the distance in miles between two TripCity objects.
void	setCity(java.lang.String initCity, java.lang.String initStateCode, int lat_deg, int lat_min, char lat_dir, int long_deg, int long_min, char long_dir) Mutator method for TripCity, when called it sets both the city name, the state code, and coordinates to provided paramaters
java.lang.String	toString() Method that returns a string that "textually represents" this object.
