(Population projection) The U.S. Census Bureau projects population based on the following assumptions:

public class Exercise_01_11 {
	public static void main(String[] args) {
		System.out.println("Population projection");
		System.out.println("Current population: 312032486");
		System.out.println("One birth every 7 seconds.");
		System.out.println("One death every 13 seconds.");
		System.out.println("One new immigrant every 45 seconds.");
		System.out.println("Yearly Population projection formula: ");
		System.out.println("Current population + ((births per year)");
		System.out.println("                   - (deaths per year)");
		System.out.println("                   + (new immigrants per year))");
		System.out.println("                   * year.");
		System.out.println("Year 1 projection: ");
		System.out.println(312032486 + (((31536000 / 7)
									 - (31536000 / 13)
									 + (31536000 / 45)) * 1));
		System.out.println("Year 2 projection: ");
		System.out.println(312032486 + (((31536000 / 7)
									 - (31536000 / 13)
									 + (31536000 / 45)) * 2));
		System.out.println("Year 3 projection: ");
		System.out.println(312032486 + (((31536000 / 7)
									 - (31536000 / 13)
									 + (31536000 / 45)) * 3));
		System.out.println("Year 4 projection: ");
		System.out.println(312032486 + (((31536000 / 7)
									 - (31536000 / 13)
									 + (31536000 / 45)) * 4));
		System.out.println("Year 5 projection: ");
		System.out.println(312032486 + (((31536000 / 7)
									 - (31536000 / 13)
