range() method of the LocalDateTime class is useful to get the minimum and maximum values as a ValueRange object for the field passed as a parameter to this method. This method returns ValueRange object only for those fields which are supported by LocalDate object. So when the field is not supported by this method then an exception is thrown by this method.
Syntax:
public ValueRange range(TemporalField field)
Parameters: This method accepts one parameter field which is the field to query the range.
Return value: This method returns the range of valid values for the field.
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// LocalDateTime.range() method  import java.time.*;import java.time.temporal.*;  public class GFG {    public static void main(String[] args)    {        // create LocalDateTime objects        LocalDateTime l1            = LocalDateTime                  .parse("2018-12-06T19:21:12");          // apply range() method of LocalDateTime class        ValueRange result            = l1.range(ChronoField.MILLI_OF_SECOND);          // print results        System.out.println("Range in MILLI_OF_SECOND: "                           + result);    }} |
Output:
Range in MILLI_OF_SECOND: 0 - 999
Program 2:
// Java program to demonstrate// LocalDateTime.range() method  import java.time.*;import java.time.temporal.*;  public class GFG {    public static void main(String[] args)    {        // create LocalDateTime objects        LocalDateTime l1            = LocalDateTime                  .parse("2018-12-06T19:21:12");          // apply range() method of LocalDateTime class        ValueRange result            = l1.range(ChronoField.DAY_OF_YEAR);          // print results        System.out.println("Range in DAY_OF_YEAR: "                           + result);    }} |
Output:
Range in DAY_OF_YEAR: 1 - 365
