Hey

[Shyamz1]

Hey there guys. I'm new to java and i am trying to create a program that prints out lines which say how many years of working you have left from a given year as command line argument. I have the following code, but it keeps displaying lines starting with the birthyear instead of the present year you have typed. The output should be:

You have 'yearsLeftWorking' years left.
In 'inSomeYear' you will have 'yearsLeftWorking' years left to work.
....
...
...
and so on each time depreciating the number of years working and increasing the year.

public class WorkFuture
{
public static void main(String [] args)
{

int retiringAge = 68;


int presentYear = Integer.parseInt(args[0]);


int birthYear = Integer.parseInt(args[1]);

int yearsLeftWorking = (retiringAge - (presentYear - birthYear));

System.out.println("You have " + yearsLeftWorking + " years left to work");

int inSomeYear = birthYear + 1;
int ageInSomeYear = inSomeYear - birthYear;
int retiringYear = birthYear + retiringAge;
for (int i=presentYear; i < retiringYear; presentYear++)

inSomeYear=inSomeYear + 1;
yearsLeftWorking = yearsLeftWorking - 1;
System.out.println("In " + inSomeYear + " you will have " + yearsLeftWorking + " years to work");


Any help?

Kind regards

Set up your for loop to begin at 0 and exit when greater than yearsLeftWorking.
say your for loop began like

for(int i=0;i<yearsLeftWorking;i++)

Now all you have to do is add i to presentYear(to get current year now) and subtract i from yearsLeftWorking(to get years left to work) through each iteration through the for loop

Hi.

it doesn't seem to work when you add i to presentYear and subtract from yearsLeftWorking as it skips out some years for some reason, but it works when u add 1 and subtract 1. But it seems to stop at "You have 24 years left to work" .. :S

Thanks

Kind Regards

Can I see what you have coded?

[Shyamz1]

Sure,

int retiringYear = birthYear + retiringAge;
for (int i=0; i < yearsLeftWorking; i++)
{
presentYear=presentYear + 1;
yearsLeftWorking = yearsLeftWorking - 1;
System.out.println("In " + presentYear + " you will have " + yearsLeftWorking + " years to work");

[al_Marshy_1981]

Sorry I should have been more specific do the subtraction/addition inside the System.out statement

for (int i=0; i < yearsLeftWorking; i++)
{
System.out.println("In " + (presentYear+i) + " you will have " + (yearsLeftWorking-i) + " years to work"); 
}

Ohhhh works finally! lol Thanks man. I'm just new to this, and i'm clearly not GOOD at it haha!

[al_Marshy_1981]

No problem, go through it all again, make sure you understand what is happening inside that final System.out statement. Just keep practicing.

[Shyamz1]

Cool! Thanks a lot mate.
