The with(TemporalAdjuster adjuster) method of the ChronoZonedDateTime interface is used to adjust this date-time using TemporalAdjuster and after adjustment returns the copy of adjusted date-time. The adjustment takes place using the specified adjuster strategy object. This instance of ChronoZonedDateTime is immutable and unaffected by this method call. A simple adjuster uses to set one of the fields, such as the year field where A more complex adjuster might set the time to the last day of the year.
Syntax:
default ChronoZonedDateTime with(TemporalAdjuster adjuster)
Parameters: This method accepts adjuster as parameter which is the adjuster to use.
Return value: This method returns a ChronoZonedDateTime 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:
