如何从java中的时区获取一天

Question

我的输入将是时区

public/

输出应该是属于那个时区的日子。

String timeZone = currentTimeZone.getID();
timezone = America/Los_Angeles

这是我到目前为止所尝试的内容。

Monday

Answer 1

Calendar calendar = Calendar.getInstance();
Calendar LATime = new GregorianCalendar(TimeZone.getTimeZone("America/Los_Angeles"));
LATime.setTimeInMillis(calendar.getTimeInMillis());
int year = LATime.get(Calendar.YEAR);
int month = LATime.get(Calendar.MONTH);
int date = LATime.get(Calendar.DATE);
int dayOfWeek = calender.get(Calendar.DAY_OF_WEEK);

试一试

Answer 2

您可以使用其他给出整数的答案，然后您可以相应地将其映射到星期几，或者您可以使用SimpleDateFormat打印星期几，如下所示：

SimpleDateFormat sdf = new SimpleDateFormat("EEEE");
Date datetime = new Date();
sdf.setTimeZone(TimeZone.getTimeZone("America/Los_Angeles"));
System.out.println("America/Los_Angeles " + sdf.format(datetime));

希望这有帮助。

我们也可以设置calendar.setFirstDayOfWeek（）;默认它是周日的开始。
