How to continue the loop after getting Null object in SpringBoot Application?

In my Code ,I have used Null Object checker and simply applied a conditional Statement there , if condition is false (ie.Object == null) it should continue the loop giving sort of warning else add that Object's value in a List.

Boolean isDobNull = 
                    Objects
                    .requireNonNull( userDob )
                    .toInstant()
                    .isBefore( 
                        Instant.now() 
                    ) 
                ;
      if(isDobNull == false || isDobNull == null){
          log.warn("DOB is missing: "+ activeUser.getUserName());
         continue;
      }else {
         // statements

            }
