ChronoLocalDate range() method in Java with Examples
Last Updated :
29 Apr, 2019
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:
import java.time.*;
import java.time.temporal.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] args)
{
ChronoLocalDate localD
= LocalDate.parse("2018-12-06");
System.out.println("ChronoLocalDate: "
+ localD);
ValueRange range
= localD.range(ChronoField.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:
import java.time.*;
import java.time.temporal.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] args)
{
ChronoLocalDate localD
= LocalDate.parse("2018-12-06");
System.out.println("ChronoLocalDate: "
+ localD);
ValueRange range
= localD.range(ChronoField.DAY_OF_YEAR);
System.out.println("Range of DAY_OF_YEAR: "
+ range);
}
}
|
Output:
ChronoLocalDate: 2018-12-06
Range of DAY_OF_YEAR: 1 - 365
