LocalTime query() Method in Java with Examples

query() method of an LocalTime class used to query this LocalTime using the specified query as parameter.The TemporalQuery object passed as parameter define the logic to be used to obtain the result from this LocalTime.

Syntax:

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.

Below programs illustrate the query() method:
Program 1:

// Java program to demonstrate 
// LocalTime.query() method 

import java.time.*; 

import java.time.temporal.*; 

public class GFG { 

    public static void main(String[] args) 

    { 

        // create LocalTime object 

        LocalTime lt = LocalTime.parse("10:15:30.00"); 

        // apply query method of LocalTime class 

        String value 

            = lt.query(TemporalQueries.precision()) 

                  .toString(); 

        // print the result 

        System.out.println("Precision value for LocalTime is "

                           + value); 

    } 
}

Output:

Precision value for LocalTime is Nanos

Program 2: Showing if query did not found the required object then it returns null.

// Java program to demonstrate 
// LocalTime.query() method 

import java.time.*; 

import java.time.temporal.*; 

public class GFG { 

    public static void main(String[] args) 

    { 

        // create LocalTime object 

        LocalTime lt = LocalTime.parse("10:15:30.00"); 

        // apply query method of LocalTime class 

        // print the result 

        System.out.println("Zone value for LocalTime is "

                           + lt.query( 

                                 TemporalQueries.offset())); 

    } 
}
