Improve
query() method of an ZonedDateTime class used to query this ZonedDateTime using the specified query as parameter.The TemporalQuery object passed as parameter define the logic to be used to obtain the result from this ZonedDateTime.
Syntax:
Java
Java
public <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:
- DateTimeException - if unable to query .
- ArithmeticException - if numeric overflow occurs.
// Java program to demonstrate
// ZonedDateTime.query() method
import java.time.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
// create ZonedDateTime object
ZonedDateTime zlt
= ZonedDateTime.parse(
"2018-10-25T23:12:31.123+02:00[Europe/Paris]");
// apply the query method of ZonedDateTime class
String value
= zlt.query(
TemporalQueries.precision())
.toString();
// print the result
System.out.println("Precision value"
+ " for ZonedDateTime is "
+ value);
}
}
// Java program to demonstrate// ZonedDateTime.query() methodimport java.time.*;import java.time.temporal.*;public class GFG { public static void main(String[] args) { // create ZonedDateTime object ZonedDateTime zlt = ZonedDateTime.parse( "2018-10-25T23:12:31.123+02:00[Europe/Paris]"); // apply the query method of ZonedDateTime class String value = zlt.query( TemporalQueries.precision()) .toString(); // print the result System.out.println("Precision value" + " for ZonedDateTime is " + value); }}
Output:
Program 2:
Precision value for ZonedDateTime is Nanos
