DATA BLOCK - city list and time difference from EST

String[] cities = { "London", "Paris", "Rome", "Seattle", "Tokyo" };

int[] timeDeltas = { 6, 7, 8, -3, -12 };

// TODO: create the ArrayList of TimeDifference objects using

new operator

// TODO: load the array list with the data with a regular for loop

//for (int i = 0; i < cities.length; i++)

{

// TODO: instantiate each TimeDifference object and add it

the ArrayList

}

// TODO: create Scanner object

// create a variable to hold a Time object reference

Time inputTime;

// prompt for a valid current time

inputTime = getValidTime(input);

// flush input buffer stream

input.nextLine();

// TODO: prompt for desired city name and receive input String

// TODO: loop to prompt user for city and call findCityTime or quit

Answer 1

In order to correctly handle this, you can create a cities class that has the city name and time difference. You can then add the cities object an arraylist. Once you prompt the user for input, you can search the arraylist checking if the city name matches the user input. Once a match is found you can retrieve that city object and get it's timedifference and get the actual time since eastern time is know.
