ChronoZonedDateTime query() method in Java with Examples
query() method of an ChronoZonedDateTime interface used to query this ChronoZonedDateTime using the specified query as parameter.The TemporalQuery object passed as parameter define the logic to be used to obtain the result from this ChronoZonedDateTime.
Syntax:
default <R> R query(TemporalQuery<R> query)
Parameters: This method accepts only one parameter query which is the query to invoke.
Return value: This method returns the query result, null may be returned.
Exception: This method throws following Exceptions:
Below programs illustrate the query() method:
Program 1:
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
ChronoZonedDateTime zlt
= ZonedDateTime.parse(
"2018-10-25T23:12:31.123+02:00[Europe/Paris]" );
String value
= zlt.query(
TemporalQueries.precision())
.toString();
System.out.println( "Precision value"
+ " for ChronoZonedDateTime is "
+ value);
}
}
|
Output:
Precision value for ChronoZonedDateTime is Nanos
Program 2:
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
ChronoZonedDateTime zlt
= ZonedDateTime.parse(
"2018-10-25T23:12:31.123+02:00[Europe/Paris]" );
System.out.println( "offset value for "
+ "ChronoZonedDateTime is "
+ zlt.query(
TemporalQueries.offset()));
}
}
|
Output:
offset value for ChronoZonedDateTime is +02:00
