java public static LocalDate getStartDateOfWeekint year int week LocalDate firstDayOfYear = LocalDateofyear 1 1; LocalDate firstDayOfFirstWeek = firstDayOfYearwithTemporalAdjustersfirs

可以在计算结束后，将startDate加上一天，从而得到正确的起始日期。修改后的代码如下：

public static LocalDate getStartDateOfWeek(int year, int week) {
    LocalDate firstDayOfYear = LocalDate.of(year, 1, 1);
    LocalDate firstDayOfFirstWeek = firstDayOfYear.with(TemporalAdjusters.firstInMonth(firstDayOfYear.getDayOfWeek()));
    LocalDate startDate = firstDayOfFirstWeek.plusWeeks(week - 1).plusDays(1);
    return startDate;
}
