public int get(TemporalField field)

DayOfWeek.get(TemporalField) returns the value of the specified field from 'this' DayOfWeek instance. If the provided TemporalField is not supported, UnsupportedTemporalTypeException is thrown.

Only ChronoField.DAY_OF_WEEK is supported by this method, all other fields of ChronoField will throw UnsupportedTemporalTypeException.

This method is defined in the interface TemporalAccessor which is implemented by this class.
