我想检查一周是否结束了jodatime

Question

我试着用from.isBefore(to)检查一周是否结束了。来自LocalDate（例如今天）和from.plusDays(6)，所以一周。现在的问题是它始终是真的。我如何修复toDate，fromDate只是计数并且在达到if条件后做某事？

LocalDate from = LocalDate.now();

LocalDate to = from.withPeriodAdded(Period.days(6), 1);

if(from.isBefore(to)) {
   //do something;
}....

Answer 1

如果你有from，并且你通过在to增加6天计算from，from将始终在之前（并且from.isBefore(to)将始终返回True）。您需要明确检查两个日期之间的差异是否为7天。

看看静态的daysBetween(ReadableInstant start, ReadableInstant end)方法。

Answer 2

好的，我解决了。我在我的日常文件中写了当前的LocalDate。然后我用index.Of从File中读取String并将其解析为LocalDate。我添加了这个Date 6 Days和来自CurrentDate的计数器。也许这不是最好的解决方案，但它有效......

    //In my Async-Class where the Files get written
          LocalDate currentDate = LocalDate.now();
          outputStream.write(currentDate.toString().getBytes());


 //In my Main-clasS
    final LocalDate currentDate = LocalDate.now(); //Current Date
    final int daysbetween = 6; //days between current date and date of file
    final int index = openfilewed().indexOf("2", 30); //Date from file
    final LocalDate[] filedate = new LocalDate[1];
    final LocalDate[] reach = new LocalDate[1];

     filedate[0] = LocalDate.parse(openfilemon().substring(index));
     reach[0] = filedate[0].plusDays(daysbetween);
           if (currentDate.isBefore(reach[0])){
              //do something
           }
