计算世界末日倒数日

看了电影《2012》，编写一个程序计算现在距离世界末日还有多少天

import java.util.*;

public class Date2010 {
    public static void main(String[] args) {
        GregorianCalendar g = new GregorianCalendar();
/*        int year = (int)g.get(Calendar.YEAR);
        int month = (int)g.get(Calendar.MONTH)+1;
        int date = (int)g.get(Calendar.DATE);
        System.out.println("Today is " + year + "-" + month + "-" + date);
*/        
        GregorianCalendar f = new GregorianCalendar(2012, Calendar.DECEMBER, 21);
        
        long dMillis = f.getTimeInMillis() - g.getTimeInMillis();
        long dDay = dMillis/(24*60*60*1000);
        
        System.out.println("今天距离2012年12月21日还有"+dDay+"日");
    }
}
