Question

Create a whole new class called Canada. It consists of an array of size 13. Each element in the array is also an array: an array of three Strings:

1. The name of a province or territory
2. The name of the capital city of the province or territory
3. The name of the largest city by population of the province or territory

Provice -------------- Capital -------------- Largest City (by population)
Ontario -------------- Toronto ------------- Toronto
Quebec -------------- Quebec City ------- Montreal
Nova Scotia --------- Halifax ------------- Halifax
New Brunswick ---- Fredericton -------- Saint John
Manitoba ----------- Winnipeg ---------- Winnipeg
British Columbia -- Victoria ------------ Vancouver
Prince Edward ----- Charlottetown ---- Charlottetown
Island
Saskatchewan ----- Regina -------------- Saskatoon
Alberta -------------- Edmonton ---------- Calgary
Newfoundland ----- St.John's ------------ St.Jon's
and Labrador

Populate the array inside the Country constructor. The following code will be useful:

public static final int BC = 0;
public static final int AB = 1;
etc...

public static final int NAME_OF_PROVINCE = 0;
public static final int NAME_OF_CAPITAL_CITY = 1;
public static final int NAME_OF_BIGGEST_CITY = 2;

provinces[BC] = {"british columbia", "victoria", "vancouver"};
provinces[AB] = {"alberta", "edmonton", "calgary"}
etc...

Create a method called public String getCapitalCityOf(String province) which returns the name of the capital city of the province (the parameter); if there is no such province, return null.

Create a method called public String getLargestCityOf(String province) which returns the name of the largest city of the province (the parameter); if there is no such province, return null.

Create a method called public String getProvinceWhoseCapitalIs(String city) which returns the name of the province whose capital city is the city (the parameter); if there is no such city, return null.

Create a method called public void displayAllProvinceInfo() which prints out all the data from the two-dimensional array in exactly the following format:

The capital city of BRITISH COLUMBIA is Victoria, but the largest city is Vancouver.
OR
The capital city of NEWFOUNDLAND AND LABRADOR is St. John’s, and it is also the largest city.

Explanation / Answer

SOURCE CODE:

public class Canada {

/*

public static final int BC = 0;   
public static final int AB = 1;
etc...

public static final int NAME_OF_PROVINCE = 0;
public static final int NAME_OF_CAPITAL_CITY = 1;
public static final int NAME_OF_BIGGEST_CITY = 2;

provinces[BC] = {"british columbia", "victoria", "vancouver"};

//This type of array initialization is not supported in Java

//And it has been ommitted purposfully

provinces[AB] = {"alberta", "edmonton", "calgary"}

//This type of array initialization is not supported in Java

//And it has been ommitted purposfully
etc...

public static final int NAME_OF_PROVINCE = 0;
