使用其他的日期和时间类如果我们只关注年份和月份，并不需要具体的日期和时间信息，那么我们可以考虑使用其他的日期和时间类型，例如YearMonth。 YearMonth类表示一个年份和月份的组合。我们可以使用YearMonth.parse方法将字符串解析为YearMonth对象，而无需关心具体的日期和时间。 类 YearMonth yearMonth = YearMonth.parse(str, formatter); System.out.println("解决方案 = null) { YearMonth reportDate = YearMonth.parse(line, formatter); System.out.println 对于每一行日期数据，我们使用YearMonth.parse方法将其解析为YearMonth对象，然后将其打印出来或进行其他的业务逻辑。
