java 获取本周起止时间

以下是获取本周起止时间的 Java 代码：

import java.time.DayOfWeek;
import java.time.LocalDate;

public class Main {
    public static void main(String[] args) {
        LocalDate today = LocalDate.now();
        LocalDate monday = today;
        LocalDate sunday = today;

        while (monday.getDayOfWeek() != DayOfWeek.MONDAY) {
            monday = monday.minusDays(1);
        }

        while (sunday.getDayOfWeek() != DayOfWeek.SUNDAY) {
            sunday = sunday.plusDays(1);
        }

        System.out.println("本周起始日期：" + monday);
        System.out.println("本周结束日期：" + sunday);
    }
}

该代码使用 `java.time.LocalDate` 类获取当前日期，并通过循环找到本周的周一和周日。最后输出本周的起始日期和结束日期。

java获取本周起止时间

以下是 Java 获取本周起止时间的代码：

Calendar calendar = Calendar.getInstance();
int dayOfWeek = calendar.get(Calendar.DAY_OF_WEEK);
calendar.add(Calendar.DAY_OF_WEEK, 1 - dayOfWeek);
Date startDate = calendar.getTime();
calendar.add(Calendar.DAY_OF_WEEK, 6);
Date endDate = calendar.getTime();

这段代码获取了当前时间所在的周的起始日期和结束日期，其中起始日期为周一，结束日期为周日。

java 获取本周起止时间 返回Date

可以使用以下代码获取本周的起止时间：

import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;

public class Main {
    public static void main(String[] args) {
        LocalDate today = LocalDate.now();
        LocalDate startOfWeek = today.with(DayOfWeek.MONDAY);
        LocalDate endOfWeek = today.with(DayOfWeek.SUNDAY);
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
        String startOfWeekStr = startOfWeek.format(formatter);
        String endOfWeekStr = endOfWeek.format(formatter);
        System.out.println("本周起始时间：" + startOfWeekStr);
        System.out.println("本周结束时间：" + endOfWeekStr);
    }
}

输出结果如下：

本周起始时间：2022-02-28
本周结束时间：2022-03-06
