The adjustInto(Temporal) method of ZoneOffset Class in java.time package is used to obtain an adjusted Temporal instance with this instance of ZoneOffset adjusted into it. This method takes the Temporal instance as parameter and returns an Temporal instance, which is the adjusted instance. Syntax:

public Temporal adjustInto(Temporal temporalInstance)

Parameters: This method accepts  a parameter temporalInstance which is the Temporal instance to be adjusted. Return Value: This method returns a Temporal instance which is the adjusted value of this Temporal instance. Exceptions: This method throws following exceptions:

  • DateTimeException: if unable to make the adjustment
  • ArithmeticException: if numeric overflow occurs.

Below examples illustrate the ZoneOffset.adjustInto() method: Example 1: 

Java




// Java code to illustrate adjustInto() method
 
import java.time.temporal.*;
import java.time.*;
 
public class GFG {
    public static void main(String[] args)
    {
 
        // Get the Temporal instance
        ZonedDateTime temporalInstance
            = ZonedDateTime.now();
 
        System.out.println("Original Temporal instance: "
                           + temporalInstance);
 
        // Get the ZoneOffset
        ZoneOffset zoneOffset
            = ZoneOffset.ofHours(5);
 
        // Using adjustInto() method
        ZonedDateTime adjustedTemporal
            = (ZonedDateTime)zoneOffset
                  .adjustInto(temporalInstance);
 
        System.out.println("Adjusted Temporal instance: "
                           + adjustedTemporal);
    }
}

Output:

Original Temporal instance: 2018-12-11T09:44:14.373Z[Etc/UTC]
Adjusted Temporal instance: 2018-12-11T09:44:14.373Z[Etc/UTC]

Example 2: 

Java




// Java code to illustrate adjustInto() method
 
import java.time.temporal.*;
import java.time.*;
 
public class GFG {
    public static void main(String[] args)
    {
 
        // Get the Temporal instance
        OffsetDateTime temporalInstance
            = OffsetDateTime.now();
 
        System.out.println("Original Temporal instance: "
                           + temporalInstance);
 
        // Get the ZoneOffset
        ZoneOffset zoneOffset
            = ZoneOffset.ofHours(5);
 
        // Using adjustInto() method
        Temporal adjustedTemporal
            = zoneOffset
                  .adjustInto(temporalInstance);
 
        System.out.println("Adjusted Temporal instance: "
                           + adjustedTemporal);
    }
}

Output:

Original Temporal instance: 2018-12-11T09:44:16.893Z
Adjusted Temporal instance: 2018-12-11T09:44:16.893+05:00
