Re: A newbie question related to using bsh

Dynamically, the JVM doesn't care about the type of reference to any object=
.  And of course, each object knows its own type anyway.  If you wish to ex=
ecute a set of scripts not knowing what their return objects will be, you'l=
l just have to put them in some collection of Object: Set<?>/ List<?>.

Presumably, since you expect to do something with those result objects, you=
'll have some idea about their types.  So you can then cast as you retrieve=
 them from said collection:

List<?> myResults =3D ...;
Number howMany =3D (Number)myResults.get(0);
Date when =3D (Date)myResults.get(1);

Make sense?

But how if those scripts would return variant types? For instance, there ar=
e 3 bsh scripts I want to collect. So in the Java application I might scan =
the dir and use =


for(...){
Object result =3D bsh.Interpreter().source(BshFileNames);
}

So the result object would be different kind of type e.g. class A, class B =
and Class C. =


Is there any chance that I can cast them dynamically?

Thanks to reply my question.
