java.time.ZonedDateTime.query() Method Example

Description

The java.time.ZonedDateTime.query(TemporalQuery<R> query) method queries this date-time using the specified query.

Declaration

Following is the declaration for java.time.ZonedDateTime.query(TemporalQuery<R> query) method.

public <R> R query(TemporalQuery<R> query)

Parameters

query − the query to invoke, not null.

Return Value

the query result, null may be returned (defined by the query).

Exceptions

• DateTimeException − if unable to query (defined by the query).

• ArithmeticException − if numeric overflow occurs (defined by the query).

Example

The following example shows the usage of java.time.ZonedDateTime.query(TemporalQuery<R> query) method.

package com.tutorialspoint;

import java.time.ZonedDateTime;
import java.time.temporal.TemporalQueries;

public class ZonedDateTimeDemo {
   public static void main(String[] args) {

      ZonedDateTime date = ZonedDateTime.parse("2017-03-28T12:25:38.492+05:30[Asia/Calcutta]");
      System.out.printf("ZonedDateTime precision is %s%n",
         date.query(TemporalQueries.precision()));
   }
}

Let us compile and run the above program, this will produce the following result −

ZonedDateTime precision is Nanos
