LocalDateTime query() Method in Java
The LocalDateTime object can be queried as required using the query method in the LocalDateTime class in Java. This method requires a single parameter i.e. the query to be invoked and it returns the result of the query.
A program that demonstrates this is given as follows −
Example
import java.time.*; import java.time.temporal.*; public class Demo { public static void main(String[] args) { LocalDateTime ldt = LocalDateTime.parse("2019-02-18T23:15:30"); System.out.println("The LocalDateTime is: " + ldt); String precision = ldt.query(TemporalQueries.precision()).toString(); System.out.println("The Precision for the LocalDateTime is: "+ precision); } }
Output
The LocalDateTime is: 2019-02-18T23:15:30 The Precision for the LocalDateTime is: Nanos
Now let us understand the above program.
First the LocalDateTime object is displayed. Then the LocalDateTime object is queried using the query() method and the query result is displayed. A code snippet that demonstrates this is as follows −
LocalDateTime ldt = LocalDateTime.parse("2019-02-18T23:15:30"); System.out.println("The LocalDateTime is: " + ldt); String precision = ldt.query(TemporalQueries.precision()).toString(); System.out.println("The Precision for the LocalDateTime is: "+ precision);
