Gregorian Calendar

[FOX427]

Hi All!
I am having difficulties with GregorianCalendar class, working with a java book that asks to implement program that prints these results:
1) the date and weekday that is hundred days from today
2) the weekday of my birthday
3) the date that is 10,000 days from my bday.
So far, I have this:

import java.util.GregorianCalendar;

public class Calendar {

	private static int DAY_OF_MONTH;
	private static int MONTH;
	private static int YEAR;
	private static int DAY_OF_WEEK;
	private static int JUNE;

	/**
	 * @param args
	 */

	public static void main(String[] args) {
		
		GregorianCalendar cal = new GregorianCalendar(); //today's date
		GregorianCalendar mybday = new GregorianCalendar(1987, Calendar.JUNE, 9); //my birthday
		
		
		// now cal is a hundred days from today
		cal.add(Calendar.DAY_OF_MONTH, 100);
		
		int dayOfMonth = cal.get(Calendar.DAY_OF_MONTH);
		int month = cal.get(Calendar.MONTH);
		int year = cal.get(Calendar.YEAR);
		int weekday = cal.get(Calendar.DAY_OF_WEEK);
		//1 is Sunday, 2 is Monday, ..., 7 is Saturday
		
		//The date and weekday that is 100 days from today
		System.out.println("The date and weekday that is 100 days from today");
		System.out.println("MONTH: " + month);
		System.out.println("YEAR: " + year);
		System.out.println("DAY OF MONTH: "+ dayOfMonth);
		System.out.println("DAY OF WEEK: "+ weekday);
		
		
		
		//My birthday's weekday
		int dayOfMonth2 = mybday.get(Calendar.DAY_OF_MONTH);
		int month2 = mybday.get(Calendar.MONTH);
		int year2 = mybday.get(Calendar.YEAR);
		int weekday2 = mybday.get(DAY_OF_WEEK);
		System.out.println("MY BIRTHDAY'S WEEKDAY IS " + weekday2);
		
		//The date that is 10,000 days from my birthday
		System.out.println("The date that is 10,000 days from my birthday");
		mybday.add(Calendar.DAY_OF_MONTH, 10000);
		
		System.out.println("MONTH: " + month2);
		System.out.println("YEAR: " + year2);
		System.out.println("DAY OF MONTH: "+ dayOfMonth2);
		System.out.println("DAY OF WEEK: "+ weekday2);
		

	}

	

}

on console windows it gives me:
The date and weekday that is 100 days from today
MONTH: 1
YEAR: 1
DAY OF MONTH: 1
DAY OF WEEK: 1
MY BIRTHDAY'S WEEKDAY IS 1
The date that is 10,000 days from my birthday
MONTH: 1
YEAR: 1
DAY OF MONTH: 1
DAY OF WEEK: 1

which is of course not correct...any ideas why it is giving me wrong results? thanks!

Big suggestion: don't give the class you've created the same name as a core Java class, and then give it constants (that are all 0 by default) that shadow the true Calendar class's constants and do nothing but confuse your program. Rename your program and import the true Calendar class and use *its* useful constants.

oh shoot! that works! thank you for your suggestions! :)
