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

 Live Demo

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);
