public class JavaCalendarExample {
    public static void main(String[] args) {
        // 获取当前日期
        LocalDate currentDate = LocalDate.now();
        // 计算上周的开始日期
        LocalDate startOfLastWeek = currentDate.minusWeeks(1).with(DayOfWeek.MONDAY);
        // 计算上周的结束日期
        LocalDate endOfLastWeek = currentDate.minusWeeks(1).with(DayOfWeek.SUNDAY);

        // 格式化日期
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
        String startDate = startOfLastWeek.format(formatter);
        String endDate = endOfLastWeek.format(formatter);

        // 输出结果
        System.out.println("上周的开始日期是：" + startDate);
        System.out.println("上周的结束日期是：" + endDate);
