/**
* Returns a copy of this date-time with the specified field set to a new value.
* <p>
* This returns a {@code LocalDateTime}, based on this one, with the value
* for the specified field changed.
* This can be used to change any supported field, such as the year, month or day-of-month.
* If it is not possible to set the value, because the field is not supported or for
* some other reason, an exception is thrown.
* <p>
* In some cases, changing the specified field can cause the resulting date-time to become invalid,
* such as changing the month from 31st January to February would make the day-of-month invalid.
* In cases like this, the field is responsible for resolving the date. Typically it will choose
* the previous valid date, which would be the last valid day of February in this example.
* <p>
* If the field is a {@link ChronoField} then the adjustment is implemented here.
* The {@link #isSupported(TemporalField) supported fields} will behave as per
* the matching method on {@link LocalDate#with(TemporalField, long) LocalDate}
* or {@link LocalTime#with(TemporalField, long) LocalTime}.
* All other {@code ChronoField} instances will throw an {@code UnsupportedTemporalTypeException}.
* <p>
* If the field is not a {@code ChronoField}, then the result of this method
* is obtained by invoking {@code TemporalField.adjustInto(Temporal, long)}
* passing {@code this} as the argument. In this case, the field determines
* whether and how to adjust the instant.
* <p>
* This instance is immutable and unaffected by this method call.
*
* @param TemporalField $field the field to set in the result, not null
* @param int $newValue the new value of the field in the result
* @return LocalDateTime a {@code LocalDateTime} based on {@code this} with the specified field set, not null
* @throws DateTimeException if the field cannot be set
* @throws UnsupportedTemporalTypeException if the field is not supported
* @throws ArithmeticException if numeric overflow occurs
