如何用Java编写今天的哪一天？

Question

我想今天写一天到控制台。例如，如果今天是星期一，请将"Monday"写入控制台。我是Java的新手，所以我还没有尝试过任何东西。

您可以尝试以下内容：

public class GetDayFromDate {

    public static void main(String[] args) {

        Date now = new Date();

        SimpleDateFormat simpleDateformat = new SimpleDateFormat("E"); // the day of the week abbreviated
        System.out.println(simpleDateformat.format(now));

        simpleDateformat = new SimpleDateFormat("EEEE"); // the day of the week spelled out completely
        System.out.println(simpleDateformat.format(now));

        Calendar calendar = Calendar.getInstance();
        calendar.setTime(now);
        System.out.println(calendar.get(Calendar.DAY_OF_WEEK)); // the day of the week in numerical format

    }
}
