The addTo(Temporal) method of Duration Class in java.time package is used add this duration to the specified temporal object, passed as the parameter. Syntax:
public Temporal addTo?(Temporal temporalObject)
Parameters: This method accepts a parameter temporalObject which is the amount to be adjusted in this duration. It should not be null. Return Value: This method returns an object of the same type with the temporalObject adjusted to it. Exception: This method throws:
- DateTimeException: if unable to add.
- ArithmeticException: if numeric overflow occurs.
Below examples illustrate the Duration.addTo() method: Example 1:Â
Java
// Java code to illustrate Duration addTo() methodÂ
import java.time.*;Â
public class GFG {Â Â Â Â public static void main(String[] args)Â Â Â Â {Â
        // Duration 1 using parse() method        Duration duration1            = Duration.parse("P2DT3H4M");Â
        // Get the time to be adjusted        LocalDateTime currentTime            = LocalDateTime.now();Â
        System.out.println("Original time: "                           + currentTime);Â
        // Adjust the time        // using addTo() method        System.out.println(            duration1                .addTo(currentTime));    }} |
Output:
Original time: 2018-11-26T07:01:13.535 2018-11-28T10:05:13.535
Example 2:Â
Java
// Java code to illustrate duration addTo() methodÂ
import java.time.*;Â
public class GFG {Â Â Â Â public static void main(String[] args)Â Â Â Â {Â
        // Duration        Duration duration2            = Duration.ofDays(-5);Â
        // Get the time to be adjusted        LocalDateTime currentTime            = LocalDateTime.now();Â
        System.out.println("Original time: "                           + currentTime);Â
        // Adjust the time        // using addTo() method        System.out.println(            duration2                .addTo(currentTime));    }} |
Output:
Original time: 2018-11-26T07:01:16.615 2018-11-21T07:01:16.615
