The range() method of a ChronoLocalDate interface is used to get the range of valid values for the field passes as a parameter. This method returns a ValueRange object which contains the minimum and maximum valid values for a field. When the field is not supported then an exception is thrown. This ChronoLocalDate is helpful to enhance the accuracy of the returned range. Syntax:
public ValueRange range(TemporalField field)
Parameters: This method accepts one single parameter field which is the field to query the range for. Return value: This method returns ValueRange which is the range of valid values for the field, not null. Exception: This method throws following Exceptions:
  • DateTimeException - if the range for the field cannot be obtained.
  • UnsupportedTemporalTypeException - if the field is not supported.
Below programs illustrate the range() method: Program 1: Java
// Java program to demonstrate
// ChronoLocalDate.range() method

import java.time.*;
import java.time.temporal.*;
import java.time.chrono.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a ChronoLocalDate object
        ChronoLocalDate localD
            = LocalDate.parse("2018-12-06");

        // print ChronoLocalDate
        System.out.println("ChronoLocalDate: "
                           + localD);

        // get range of Days field
        // from ChronoLocalDate using range method
        ValueRange range
            = localD.range(ChronoField.DAY_OF_MONTH);

        // print range of DAY_OF_MONTH
        System.out.println("Range of DAY_OF_MONTH: "
                           + range);
    }
}
Output:
ChronoLocalDate: 2018-12-06
Range of DAY_OF_MONTH: 1 - 31
Program 2: Java
// Java program to demonstrate
// ChronoLocalDate.range() method

import java.time.*;
import java.time.temporal.*;
import java.time.chrono.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a ChronoLocalDate object
        ChronoLocalDate localD
            = LocalDate.parse("2018-12-06");

        // print ChronoLocalDate
        System.out.println("ChronoLocalDate: "
                           + localD);

        // get range of DAY_OF_YEAR field
        // from ChronoLocalDate using range method
        ValueRange range
            = localD.range(ChronoField.DAY_OF_YEAR);

        // print range of DAY_OF_YEAR
        System.out.println("Range of DAY_OF_YEAR: "
                           + range);
    }
}
Output:
ChronoLocalDate: 2018-12-06
Range of DAY_OF_YEAR: 1 - 365
