java的GreggorianCalendar的小问题

Question

java

Answer 1

import java.text.DateFormatSymbols;
import java.util.*;
public class Calendar {public static void main(String[] args)
{
GregorianCalendar d = new GregorianCalendar();
int today = d.get(Calendar.DAY_OF_MONTH);
int month = d.get(Calendar.MONTH);
d.set(Calendar.DAY_OF_MONTH,1);
int weekday = d.get(Calendar.DAY_OF_WEEK);
int firstdayofweek = d.getFirstDayOfWeek();
int indents = 0;
do
{
indents++;
d.add(DAY_OF_MONTH, 1);
weekday = d.get(Calendar.DAY_OF_WEEK);
}
while(weekday!=d.getFirstDayOfWeek());

String[] weekdayNAME = new DateFormatSymbols().getShortMonths();
do
{
System.out.printf("%4s",weekdayNAME[weekday]);
d.add(Calendar.DAY_OF_MONTH, 1);
weekday = d.get(Calendar.DAY_OF_WEEK);
}
while(weekday!=d.getFirstDayOfWeek());

weekday = d.get(Calendar.DAY_OF_WEEK);

System.out.println();
for(int i = 0;i < indents;i++)
System.out.print("    ");

d.set(Calendar.DAY_OF_MONTH, 1);
do
{
int day = d.get(Calendar.DAY_OF_MONTH);
System.out.printf("%3d",day);
if(day == today)
System.out.print("*");
d.add(Calendar.DAY_OF_MONTH, 1);
weekday = d.get(Calendar.DAY_OF_WEEK);
if(weekday == d.getFirstDayOfWeek())
System.out.println();
}
while(month == d.get(Calendar.MONTH));

if(weekday != d.getFirstDayOfWeek()) System.out.println();
}
}
刚才没发好，重新发一下，这里面的Calendar.DAY_OF_MONTH    Calendar.DAY_OF_WEEK之类的提示无法解析

Answer 2

你这是自己定义了一个类叫Calendar？  
public class Calendar {public static void main(String[] args)
{....Calendar.DAY_OF_WEEK然后你自己又用这个类的属性 DAY_OF_WEEK  他这些属性怎么会存在？   java.util.Calendar.DAY_OF_WEEK才行吧？

太感谢了，这么个小问题啊，刚学java没注意到这个类名的问题，当时就随便定义了个名字，没想到正好冲突了
