Question

Programming and Logic 1: Java

In this program you'll need to store the populations of 12 countries.

Define two arrays that will be used in parallel to store the names of the countries and their populations.

Write a loop that uses these arrays to print each country's name and its population.

For an extra 7 points

Add a loop in your main method which asks the user running it if they would like to look up a given country's population. When they indicate “No” the program terminates.

Prompt user: What country would you like to look up?

Upon user entering something the program searches the country names array to see if it's there..

If it is output the country name searched for and it's corresponding population

If it is not output the country name searched for and that it was not found.

Explanation / Answer

// Import statements

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

//Class begins

public class PopulationOfCountries

{

// Main Method

public static void main(String[] args) throws IOException {

//Population Array

int[] population = new int[12];

//Country Array

String[] countryNames = new String[12];

// Initializing population values

population= new int[]{136796000,126267000,319111000,21346200,18817200,72721212,12642323,36444564,1239445,2436453,1123445,1212344};

//Initializing Country names

countryNames= new String[]{"China","America","United States","Indonesia","Brazil","Nigeria","Bangadesh","Poland","BHARAT","Thailand","Newjersy","Singapore"};

// FOr loop for printing data

for(int i=0;i<population.length;i++){

System.out.println(countryNames[i]+ "--" +population[i] );

}

// For loop asking the requirement of user

for (int i= 1; i<i+1; i++){

System.out.println("Would you like to lookup a countrys population [Yes OR No]");

//reading information from user

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

String choice =br.readLine();

//Exit the code if the user send NO

if(choice.equalsIgnoreCase("No")){

System.exit(0);

}

else{

//Printing the population based on the user's required country name

System.out.println("What country would you like to look up?");

String countryName =br.readLine();

for (i = 0; i < 12; i ++)

{

if(countryName.equalsIgnoreCase(countryNames[i]))

{

System.out.println(countryNames[i] + "----" + population[i]);

break;

}

}

}

}

}

}
