LocalDateTime._with

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 field the field to set _in the result, not null @param newValue the new value of the field _in the result @return 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
