import java.time.temporal.ValueRange;

public class LocalDateDemo

{

    public static void main(String[] args)

    {

        LocalDate date = LocalDate.parse("2017-12-03");

        /*

         * Parameters:

         * 

         * field - the field to query the range for, not null

         * 

         * Returns:

         * 

         * the range of valid values for the field, not null

         */

        ValueRange dayOfMonthRange = date.range(ChronoField.DAY_OF_MONTH);

        System.out.println("dayOfMonthRange = "+dayOfMonthRange);

        System.out.println("Max DayOfMonth = "+ dayOfMonthRange.getMaximum());

        System.out.println("Min DayOfMonth = "+ dayOfMonthRange.getMinimum());

        System.out.println("--------------------------");

        ValueRange monthOfYearRange = date.range(ChronoField.MONTH_OF_YEAR);

        System.out.println("monthOfYearRange = "+monthOfYearRange);

        System.out.println("Max MonthOfYear = "+ monthOfYearRange.getMaximum());

        System.out.println("Min MonthOfYear = "+ monthOfYearRange.getMinimum());

        System.out.println("--------------------------");

        ValueRange dayOfYearRange = date.range(ChronoField.DAY_OF_YEAR);

        System.out.println("dayOfYearRange = "+dayOfYearRange);

        System.out.println("Max DayOfYear = "+ dayOfYearRange.getMaximum());

        System.out.println("Min DayOfYear = "+ dayOfYearRange.getMinimum());

    }

}

Output

dayOfMonthRange = 1 - 31

Max DayOfMonth = 31

Min DayOfMonth = 1

--------------------------

monthOfYearRange = 1 - 12

Max MonthOfYear = 12

Min MonthOfYear = 1

--------------------------

dayOfYearRange = 1 - 365

Max DayOfYear = 365

Min DayOfYear = 1
