Help...Why won't this compile?

What you're doing is using days after the if statement; without curly braces only a valid statement is allowed.

But if you add curly braces, days will be available only in the if block.

So what you should do is:

import java.util.Calendar;

import javax.swing.JOptionPane;

public class GetAge{

public static void main(String[] args){

int month=Integer.parseInt(JOptionPane.showInputDialog

(null,"Enter what month(MM) you were born:"));

int day=Integer.parseInt(JOptionPane.showInputDialog

(null,"Enter what day(dd) you were born:"));

int year=Integer.parseInt(JOptionPane.showInputDialog

(null,"Enter what year(yyyy) you were born:"));

Calendar rightNow = Calendar.getInstance();

int year2 = rightNow.get(Calendar.YEAR);

int day2 = rightNow.get(Calendar.DATE);

int month2 = rightNow.get(Calendar.MONTH)+1;

int years = year2-year-1;

int months = month2-month+12;

int days = 0;//declare here

if(day2 >= day)

days = day2-day; //...and use here

else

days = day-day2+8;//..and here

JOptionPane.showMessageDialog(null,"You are: " + years

+ " years " + months + " months and " + days + " days old.");

}

}
