import java.time.temporal.TemporalQuery;
/*from w ww  .ja va 2  s .c  om*/
public class Main {
  public static void main(String[] argv) {
    LocalDate date = LocalDate.parse("2013-01-12");
    TemporalQuery<Quarter> quarterOfYearQuery = new QuarterOfYearQuery(); 
    
    System.out.println(date.query(quarterOfYearQuery));
  }
}
enum Quarter {
  FIRST, SECOND, THIRD, FOURTH;
}
class QuarterOfYearQuery implements TemporalQuery<Quarter> {
  @Override
  public Quarter queryFrom(TemporalAccessor temporal) {
      LocalDate now = LocalDate.from(temporal);

      if(now.isBefore(now.with(Month.APRIL).withDayOfMonth(1))) {
          return Quarter.FIRST;
      } else if(now.isBefore(now.with(Month.JULY).withDayOfMonth(1))) {
          return Quarter.SECOND;
      } else if(now.isBefore(now.with(Month.NOVEMBER).withDayOfMonth(1))) {
          return Quarter.THIRD;
      } else {
         return Quarter.FOURTH;
      }
  }
}
