Here's a similar table declaring variables so you can update it easier
int Population ;
Population = 312032486;
//My equations for calculating births in a year
long births ;
births = ((60 * 60 *24 *365) / 7) ;
// Calculation for deaths in a year
long deaths ;
deaths = ((60 * 60 *24 *365) / 13 ) ;
//Calculation for immigrants per year
long immigrants ;
immigrants = ((60 * 60 *24 *365) / 45 ) ;
//Calculation for rate of change
long rateofchange ;
rateofchange = births - deaths + immigrants ;
//Output for births in a year
System.out.println("Number of births in a year = " + births ) ;
//Output for deaths in a year
System.out.println("Number of deaths in a year = " + deaths);
//Output for immigrants per year
System.out.println("Number of immigrants per year = " + immigrants );
//Table with population at year 0 through year 5
+
"\n0\t\t\t" + Population +
"\n1\t\t\t" + (Population + rateofchange) +
"\n2\t\t\t" + (Population + (rateofchange * 2)) +
"\n3\t\t\t" + (Population + (rateofchange * 3)) +
"\n4\t\t\t" +(Population + (rateofchange * 4)) +
"\n5\t\t\t" + (Population + (rateofchange * 5))) ;

I hope your break down all the videos like this, as I think it’s more important to learn to solve the problem first before you write code! Because the syntax part is easy but the problem solving and reasoning needs to be explained just like you did here. Thanks man!!

Thanks DUDE! Way to break down the reasoning to code, awesome!!!
