ZonedDateTime range() method in Java with Examples

The range() method of a ZonedDateTime class is used to get the range of valid values for the field passes as a parameter. This method returns ValueRange object which contains the minimum and maximum valid values for a field. This ZonedDateTime is helpful to enhance the accuracy of the returned range. When the field is not supported and method is unable to return range values then an exception is thrown.

Syntax:

public ValueRange range(TemporalField field)

Parameters: This method accepts one single parameter field which is the field to get range of values.

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 program to demonstrate
// ZonedDateTime.range() method

import java.time.*;
import java.time.temporal.ChronoField;
import java.time.temporal.ValueRange;

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

        // create a ZonedDateTime object
        ZonedDateTime zonedDT
            = ZonedDateTime
                  .parse(
                      "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]");

        // print ZonedDateTime
        System.out.println("ZonedDateTime of Calcutta: "
                           + zonedDT);

        // get range of MILLI_OF_SECOND field
        // from ZonedDateTime using range method
        ValueRange range
            = zonedDT.range(ChronoField.MILLI_OF_SECOND);

        // print range of MILLI_OF_SECOND
        System.out.println("Range of MILLI_OF_SECOND: "
                           + range);
    }
}

Output:

ZonedDateTime of Calcutta: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
Range of MILLI_OF_SECOND: 0 - 999

Program 2:

// Java program to demonstrate
// ZonedDateTime.range() method

import java.time.*;
import java.time.temporal.ChronoField;
import java.time.temporal.ValueRange;

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

        // create a ZonedDateTime object
        ZonedDateTime zonedDT
            = ZonedDateTime
                  .parse(
                      "2018-10-25T23:12:31.123+02:00[Europe/Paris]");

        // print ZonedDateTime
        System.out.println("ZonedDateTime of Calcutta: "
                           + zonedDT);

        // get range of NANO_OF_SECOND field
        // from zonedDateTime using range method
        ValueRange range
            = zonedDT.range(ChronoField.NANO_OF_SECOND);

        // print range of NANO_OF_SECOND
        System.out.println("Range of NANO_OF_SECOND: "
                           + range);
    }
}

Output:

ZonedDateTime of Calcutta: 2018-10-25T23:12:31.123+02:00[Europe/Paris]
Range of NANO_OF_SECOND: 0 - 999999999
