You can arrange for the one-parameter constructors in the Movie
and
Symphony
classes to call the one-parameter Attraction
constructor, shown, for example, in Segment 299. Ordinarily,
all constructors call only the zero-parameter constructor in the direct
superclass.
Whenever you want a constructor to
hand one or more
arguments to another constructor in the direct superclass, you modify the
constructor's definition by adding, as the first statement in that
constructor, a statement consisting of the super
keyword
followed by an argument list.
