我正在使用 Java 8 时间库从今天的日期确定前几周和前一年，然后将这些值存储在地图中。我想我已经找到了正确获取周数的方法，但我不完全确定获取年份的正确方法是什么。当前代码如下：
int weeksLimit = 5; // this value is passed into the method, but just setting it here as an example
Map<Integer, Integer> yearWeeks = new HashMap<Integer, Integer>();
LocalDate ld = LocalDate.now();
WeekFields weekFields = WeekFields.of(DayOfWeek.SUNDAY, 4);
for (int i = weeksLimit; i > 0; i--) {
LocalDate pastDate = ld.minusWeeks(i);
yearWeeks.put(pastDate.getYear(), pastDate.get(weekFields.weekOfWeekBasedYear()));
}
我不相信pastDate.getYear()是正确的用法。结果我想要的是：
