OffsetTime with() Method in Java with Examples

  • Last Updated : 15 Jan, 2019
Geek Week

In OffsetTime class, there are two types of with() method depending upon the parameters passed to it.

with(TemporalAdjuster adjuster)

with(TemporalAdjuster adjuster) method of the OffsetTime class used to adjusted this OffsetTime using TemporalAdjuster and after adjustment returns the copy of adjusted OffsetTime.The adjustment takes place using the specified adjuster strategy object. This instance of OffsetTime is immutable and unaffected by this method call.

Syntax:

public OffsetTime with(TemporalAdjuster adjuster)

Parameters: This method accepts adjuster as parameter which is the adjuster to use.

Return value: This method returns a OffsetTime based on this with the adjustment made.



Exception: This method throws following Exceptions:

  • DateTimeException – if the adjustment cannot be made.
  • ArithmeticException – if numeric overflow occurs.

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




// Java program to demonstrate
// OffsetTime.with() method
  
import java.time.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create a OffsetTime object
        OffsetTime off
            = OffsetTime.parse("19:19:50+06:00");
  
        // print instance
        System.out.println("OffsetTime before"
                           + " adjustment: "
                           + off);
  
        // apply with method of OffsetTime class
        OffsetTime updatedlocal = off.with(LocalTime.NOON);
  
        // print instance
        System.out.println("OffsetTime after"
                           + " adjustment: "
                           + updatedlocal);
    }
}
Output:
OffsetTime before adjustment: 19:19:50+06:00
OffsetTime after adjustment: 12:00+06:00

with(TemporalField field, long newValue)

with(TemporalField field, long newValue) method of the OffsetTime class used to set the specified field of OffsetTime to a new value and returns the copy of new time.This method can be used to change any supported field, such as the hour, minute or second. An exception is thrown If setting the new value is not possible due to the field is not supported or for some other reason. This instance of OffsetTime is immutable and unaffected by this method call.

Syntax:

public OffsetTime with(TemporalField field, long newValue)

Parameters: This method accepts field which is the field to set in the result and newValue which the new value of the field in the result as parameters.

Return value: This method returns a OffsetTime based on this with the specified field set.

Exception: This method throws following Exceptions:

  • DateTimeException – if the adjustment cannot be made.
  • UnsupportedTemporalTypeException – if the field is not supported.
  • ArithmeticException – if numeric overflow occurs.

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




// Java program to demonstrate
// OffsetTime.with() method
  
import java.time.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create a OffsetTime object
        OffsetTime off
            = OffsetTime.parse("19:19:50+06:00");
  
        // print instance
        System.out.println("OffsetTime before"
                           + " applying method: "
                           + off);
  
        // apply with method of OffsetTime class
        OffsetTime updatedlocal
            = off.with(
                ChronoField.HOUR_OF_DAY, 23);
  
        // print instance
        System.out.println("OffsetTime after"
                           + " applying method: "
                           + updatedlocal);
    }
}
Output:
OffsetTime before applying method: 19:19:50+06:00
OffsetTime after applying method: 23:19:50+06:00
