Question

(Population projection) The U.S. Census Bureau projects population based on the following assumptions: One birth every 7 seconds One death every 13 seconds One new immigrant every 45 seconds Write a program to display the population for each of the next five years. Assume the current population is 312,032,486 and one year has 365 days. Hint: In Java, if two integers perform division, the result is an integer. The fractional part is truncated. For example,5 / 4 is 1 (not 1.25) and 10 / 4 is 2 (not 2.5). To get an accurate result with the fractional part, one of the values involved in the division must be a number with a decimal point. For example, 5.0 / 4 is 1.25 .

Explanation / Answer

class popu_project
{
   public static void main(String args[])
   {
       int totsec,birth, death, imm, totyear,totpop;

       totsec=60*60*24*365;
       birth=totsec/7;

       death=totsec/13;

       imm = totsec/45;
      
       totyear=birth+imm-death;

       totpop=312032486+totyear*5;

       System.out.println("Total population after 5

years will be"+totpop);
   }
}
