I am working with this code:

public class Date {

private final int month;
private final int day;
private final int year;

public Date(int m, int d, int y) {
if (!increment(m, d, y))
throw new RuntimeException("Invalid");
month = m;
day = d;
year = y;
}
private static boolean increment(int m, int d, int y) {
int[] DAYS = { 0, 31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 };
if (m < 1 || m > 12)
return false;
if (d < 1 || d > DAYS[m])
return false;
if (m == 2 && d == 29 && !isLeapYear(y))
return false;
return true;
}
private static boolean isLeapYear(int y) {
if (y % 400 == 0)
return true;
if (y % 100 == 0)
return false;
return (y % 4 == 0);
}
public Date next() {
if (increment(month, day + 1, year))
return new Date(month, day + 1, year);
else if (increment(month + 1, 1, year))
return new Date(month + 1, 1, year);
else
return new Date(1, 1, year + 1);
}
public String toString() {
return day + "-" + month + "-" + year;
}
public static void main(String[] args) {
Date today = new Date(9, 30, 2010);
System.out.println(today);
for (int i = 0; i < 35; i++) {
today = today.next();
System.out.println(today);
}
}
}

What I can not figure out how to do is now create a separate file that will ask the user to input a month, a day and a year and asks the user how many days ahead to show. I know I will use JOptionPane.showInputDialog to ask for the user input, but how will I pass it back to the code to show the current day and then the entered number of days in advance to show?

A very nice indentation and totally consistent but not very readable ...

kind regards,

When I pasted my code between the code tags it removed my indentions...

Strange; I copied thousands snippets of code, straight from an Eclipse editor or from vi, and never did this forum software remove my indentation; whether tabs or spaces ...

Ah, but you didn't copy form the floral subcontinent so-called tutorial site with the crappy codez, which is where this came from.

Correct, I am working on a similar project, in my mind, I was thinking let me get the ins-and-out of exactly how this code runs from start-to-finish and then let me take what I learn and apply to my project.

I have written this code:

What made you wait 667 days to ask about something you posted as an answer to someone else's question on 23 July 2010?

I did not post this answer. I was googling a to how to start my project (which I said is very similar) and came across that code. So I began working with that code to see exactly how it worked, but I am unable to get a piece of it figured out (and I will have to do the same thing in my code when I begin to write it).

[DarrylBurke]

In that case, why did you say this?

Force of habit. I will modify my original post.
