获取根据当前时间 获取本周内每一天的开始时间与结束时间的时间段 最后的时间为59:59:59 输出类型为Date, 格式为2020-09-09 00:10:10 java

以下是Java代码实现：

import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;
import java.time.format.DateTimeFormatter;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        // 获取当前日期时间
        LocalDateTime now = LocalDateTime.now();

        // 计算本周的开始日期时间和结束日期时间
        LocalDateTime startOfWeek = now.with(DayOfWeek.MONDAY).with(LocalTime.MIN);
        LocalDateTime endOfWeek = now.with(DayOfWeek.SUNDAY).with(LocalTime.MAX);

        // 构造每一天的开始日期时间和结束日期时间列表
        List<LocalDateTime[]> dayRanges = new ArrayList<>();
        for (LocalDateTime date = startOfWeek; !date.isAfter(endOfWeek); date = date.plusDays(1)) {
            LocalDateTime startOfDay = date.with(LocalTime.MIN);
            LocalDateTime endOfDay = date.with(LocalTime.MAX);
            dayRanges.add(new LocalDateTime[]{startOfDay, endOfDay});
        }

        // 将每一天的开始日期时间和结束日期时间转换为指定格式的字符串，并输出
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        for (LocalDateTime[] range : dayRanges) {
            String startTime = range[0].format(formatter);
            String endTime = range[1].withHour(23).withMinute(59).withSecond(59).format(formatter);
            System.out.println(startTime + " - " + endTime);
        }
    }
}

输出结果如下所示：
