呃，自己写一个方法好了。这个不难。

[code="java"]
public static void main( String[] args)
{
printWeekAndDay(new Date());
}

public static void printWeekAndDay(Date date)
{
/* set the date */
GregorianCalendar calendar = new GregorianCalendar();
calendar.setGregorianChange(date);

int diff = GregorianCalendar.SUNDAY - calendar.get(GregorianCalendar.DAY_OF_WEEK);

/* start from sunday */
calendar.add(GregorianCalendar.DAY_OF_MONTH, diff);

/* print week and date in this week */
for (int i = GregorianCalendar.SUNDAY; i <= GregorianCalendar.SATURDAY; i++)
{
    System.out.println(calendar.getTime());
    calendar.add(GregorianCalendar.DAY_OF_MONTH, 1);
}

}
[/code]
