问题描述

我有一个日期，我需要知道星期几，所以我使用了一个 GregorianCalendar 对象，但我得到了一些不正确的日期.

I have a date and I need to know the day of the week, so I used a GregorianCalendar object but I get back some dates that are incorrect.

GregorianCalendar calendar = new GregorianCalendar(year, month, day);
int i = calendar.get(Calendar.DAY_OF_WEEK);

我做错了什么?

谢谢！

编辑解决方案:

mont--;
GregorianCalendar calendar = new GregorianCalendar(year, month, day);
int i = calendar.get(Calendar.DAY_OF_WEEK);

    if(i == 2){
        dayOfTheWeek = "Mon";
    } else if (i==3){
        dayOfTheWeek = "Tue";
    } else if (i==4){
        dayOfTheWeek = "Wed";
    } else if (i==5){
        dayOfTheWeek = "Thu";
    } else if (i==6){
        dayOfTheWeek = "Fri";
    } else if (i==7){
        dayOfTheWeek = "Sat";
    } else if (i==1){
        dayOfTheWeek = "Sun";
    }

推荐答案

TimeZone timezone = TimeZone.getDefault();
Calendar calendar = new GregorianCalendar(timezone);
calendar.set(year, month, day, hour, minute, second);

String monthName=calendar.getDisplayName(Calendar.MONTH, Calendar.SHORT, Locale.getDefault());//Locale.US);
String dayName=calendar.getDisplayName(Calendar.DAY_OF_WEEK, Calendar.SHORT, Locale.getDefault());//Locale.US);
