Chapter 6, Problem 12PE

Explanation of Solution

Program:

File name: “Population.java”

//Define a class named Population

public class Population

{

    //Define main method

    public static void main(String[] args)

    {

        //Declare variables and initialize the values

        //set growth rate in percent

        double RATE_OF_GROWTH_OF_MEXICO=0.0101;

        //set decay rate in percent

        double RATE_OF_DECAY_OF_USA=0.0015;

        //set years

        int years=1;

        //Set Mexico population as 128 million

        double mexicoPopulation=128000000;

        //Set USA population as 323 million

        double usaPopulation=323000000;

        //Print the result

System.out.printf("%-10s%-20s%-15s\n","Years","Mexico","USA");

        /*While condition that checks if the Mexico

        population is less than USA population */

        while (mexicoPopulation<usaPopulation)

        {

            //Print the result
