Problem:compliles but won't run

Posted: Oct 14, 2005 12:17 PM

I'm using JDK5 and textpad 4.7.3.
Here is the code, if someone can tell me what is wrong and why it won't run I'd really appreciate it.
P.S. many thanks

import java.util.ArrayList;
import java.util.GregorianCalendar;

public class ArrayListStrings1
{
public static void main(String[] args)
{
GregorianCalendar aDay = new GregorianCalendar();

int year = aDay.get(GregorianCalendar.YEAR);
int month = 1 + aDay.get(GregorianCalendar.MONTH);
int day = aDay.get(GregorianCalendar.DATE);
String dateOne = "\n" + year + "/" + month + "/" + day;
aDay.add(GregorianCalendar.DATE, 14);

year = aDay.get(GregorianCalendar.YEAR);
month = 1 + aDay.get(GregorianCalendar.MONTH);
day = aDay.get(GregorianCalendar.DATE);
String dateTwo = "\n" + year + "/" + month + "/" + day;
aDay.add(GregorianCalendar.DATE, 14);

year = aDay.get(GregorianCalendar.YEAR);
month = 1 + aDay.get(GregorianCalendar.MONTH);
day = aDay.get(GregorianCalendar.DATE);
String dateThree = "\n" + year + "/" + month + "/" + day;
aDay.add(GregorianCalendar.DATE, 14);

year = aDay.get(GregorianCalendar.YEAR);
month = 1 + aDay.get(GregorianCalendar.MONTH);
day = aDay.get(GregorianCalendar.DATE);
String dateFour = "\n" + year + "/" + month + "/" + day;

//Make ArrayList of four dates, imported java.util.ArrayList

ArrayList fourFortnights = new ArrayList();

fourFortnights.add( dateOne );
fourFortnights.add( dateTwo );
fourFortnights.add( dateThree );
fourFortnights.add( dateFour );
}
}

Simply Add the line below as the last line of main method.
System.out.print(fourFortnights);
Then compile and run.

Sorry,
I forgot to include System.out.println(fourFortnights); in my posting, but it is in the code. I am getting a runtime error and I was hoping someone could explain why.

Well It runs perfectly.But if you are getting runtime errors I need to know what errors you are getting.Send a listing of errors.
