java 获取上周的每一天日期

下面是 Java 代码获取上周的每一天日期：

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

public class LastWeekDates {
    public static void main(String[] args) {
        LocalDate today = LocalDate.now();
        LocalDate lastWeekStart = today.minusWeeks(1).with(TemporalAdjusters.previousOrSame(DayOfWeek.MONDAY));
        LocalDate lastWeekEnd = today.minusWeeks(1).with(TemporalAdjusters.nextOrSame(DayOfWeek.SUNDAY));

        for (LocalDate date = lastWeekStart; !date.isAfter(lastWeekEnd); date = date.plusDays(1)) {
            System.out.println(date.format(DateTimeFormatter.ofPattern("yyyy-MM-dd")));
        }
    }
}

这个程序会输出上周每一天的日期，格式为 yyyy-MM-dd。你可以根据自己的需要修改日期格式和输出方式。
