谢谢各位解答,我的代码如下,各位看下有没什么问题:
String QEndDate= (String)request.getParameter("EndDate");

Calendar calendar = new GregorianCalendar();
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
Date Tdate = (Date) format.parse(QEndDate);
calendar.setTime(Tdate);
String WeekName = "";
switch(calendar.get(Calendar.DAY_OF_WEEK)){
case 1:
WeekName = "星期天";
break;
case 2:
WeekName = "星期一";
break;
case 3:
WeekName = "星期二";
break;
case 4:
WeekName = "星期三";
break;
case 5:
WeekName = "星期四";
break;
case 6:
WeekName = "星期五";
break;
case 7:
WeekName = "星期六";
break;
}
