How to compare LocalDate instances Java 8

Question

I am writing an app that needs to be quite accurate in dates and I wonder how can I compare LocalDate instances   for now I was using something like   LocalDate localdate1   LocalDate   now    LocalDate localdate2   someService getSomeDate    localdate1 equals localdate2     But I noticed that my app is giving me some confusing results  and I think it is because of the date comparing   I am thinking about obtaining the time from 1970  in long and compare those two  but I must be easier  I am sure of it

I believe this snippet will also be helpful in a situation where the dates comparison spans more than two entries   static final int COMPARE EARLIEST   0   static final int COMPARE MOST RECENT   1    public LocalDate getTargetDate List lt LocalDate gt  datesList  int comparatorType        LocalDate refDate   null     switch comparatorType              case COMPARE EARLIEST                    returns the most earliest of the date entries           refDate    LocalDate  datesList stream   min Comparator comparing item - gt                         item toDateTimeAtCurrentTime     get              break          case COMPARE MOST RECENT              returns the most recent of the date entries            refDate    LocalDate  datesList stream   max Comparator comparing item - gt                       item toDateTimeAtCurrentTime     get              break           return refDate

Using equals    LocalDate does override equals   int compareTo0 LocalDate otherDate        int cmp    year - otherDate year       if  cmp    0            cmp    month - otherDate month           if  cmp    0                cmp    day - otherDate day                       return cmp      If you are not happy with the result of equals    you are good using the predefined methods of LocalDate    isAfter   isBefore   isEqual      Notice that all of those method are using the compareTo0   method and just check the cmp value  if you are still getting weird result  which you shouldn t   please attach an example of input and output
