java 获取本周周一0点和周日24点

你可以使用 Calendar 类来获取本周的周一和周日的时间。具体实现代码如下：

import java.util.Calendar;

public class Main {
    public static void main(String[] args) {
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);
        calendar.set(Calendar.HOUR_OF_DAY, );
        calendar.set(Calendar.MINUTE, );
        calendar.set(Calendar.SECOND, );
        calendar.set(Calendar.MILLISECOND, );
        System.out.println("本周周一点：" + calendar.getTime());

        calendar.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY);
        calendar.set(Calendar.HOUR_OF_DAY, 23);
        calendar.set(Calendar.MINUTE, 59);
        calendar.set(Calendar.SECOND, 59);
        calendar.set(Calendar.MILLISECOND, 999);
        System.out.println("本周周日24点：" + calendar.getTime());
    }
}

输出结果如下：

本周周一点：Mon Sep 27 00:00:00 CST 2021
本周周日24点：Sun Oct 03 23:59:59 CST 2021
