Thread: Please help with simple output.

Hello, This is my first time posting and I'd like to thank you guys in advance and I'm glad I have a resource to help me when I'm completely over my head. I just began a java course and I had to write a program that would display the population each year for five years. I used a linear population increase. But I cannot get the answers to format in an easily recognizable number. I know I could use the int variable, but I'm supposed to be as accurate and it displays as 3.14812582703967E8. Please help and thank you.

public class Population {
 
	public static void main(String[] args) {
		// TODO Auto-generated method stub
 
		double births = 60 / 7.0;
		double birthsPerHour = births * 60;
		double birthsPerDay = birthsPerHour * 24;
		double birthsPerYear = birthsPerDay * 365; //births over a year
 
		double deaths = 60 / 13.0;
		double deathsPerHour = deaths * 60;
		double deathsPerDay = deathsPerHour * 24;
		double deathsPerYear = deathsPerDay * 365;//deaths over a year
 
		double immigrants = 60 / 45.0;
		double immigrantsPerHour = immigrants * 60;
		double immigrantsPerDay = immigrantsPerHour * 24;
		double immigrantsPerYear = immigrantsPerDay * 365;//immigrants over a year
 
		int population =  312032486;
		double population1 =  (population + birthsPerYear + immigrantsPerYear) - deathsPerYear;
 
	System.out.println("The population for year 1 is " + population1); //print population year 1
 
		double population2 = (population1 + immigrantsPerYear + birthsPerYear) - deathsPerYear;
 
	System.out.println("The population for year 2 is " + population2); //print population year 2
 
		double population3 = (population2 + immigrantsPerYear + birthsPerYear) - deathsPerYear;
 
	System.out.println("The population for year 3 is " + population3);//print population year 3
 
		double population4 = (population3 + immigrantsPerYear + birthsPerYear) - deathsPerYear;
 
	System.out.println("The population for year 4 is " + population4); //print population year 4
 
		double population5 = population4 + immigrantsPerYear + birthsPerYear - deathsPerYear;
 
	System.out.println("The population for year 5 is " + population5); //print population year 5
 
 
 
 
	}
 
}
