问题描述

目前,我正在创建一个 java 日程安排应用程序,我想知道如何在使用 Calendar 类获取一周的第一天时找到一周中的当前日期.

At the moment, I'm creating a java schedule app and I was wondering how to find the current day of the week while using the Calendar class to get the first day of the week.

这是我在课堂上用来设置一周时间表的方法

Here is the method I'm using in a class in order to set up a week schedule

public static String getSunday() {
    SimpleDateFormat d = new SimpleDateFormat(dayDate);
    Calendar specific = cal;
    specific.add(Calendar.DAY_OF_YEAR, (cal.getFirstDayOfWeek() - ??));
    return d.format(specific.getTime());
}

推荐答案

可以通过Calendar.DAY_OF_WEEK调用get()获取当前星期几/p>

You can get the current day of the week by calling get() with Calendar.DAY_OF_WEEK

public int getTodaysDayOfWeek() {
  final Calendar c = Calendar.getInstance();
  return c.get(Calendar.DAY_OF_WEEK);
}

另外,虽然我不确定我是否完全理解您要做什么,但对我来说它看起来很可疑.(例如 cal 是什么?)

Also, while I'm not sure I understand exactly what you're trying to do, it looks fishy to me. (What's cal for example?)
