why can't java have types as arguments ?
eg can't have Vector of reals where compiler checks type.
(example taken from http://www.ics.uci.edu/~kibler/javacourse/java.html )
I think that might be outdated, as now you can do:
Vector<Real> vec = new Vector<Real>();
and the compiler will signal an error if you try to :
vec.add(new Animal());
Because that page is 12 years old and not very well written besides. Java actually does have generics .
Use a collection with generics support, such as Vector<Double>
instead of its non generic counterpart.
Nowadyas Java does support "types as parameters", or genericity. Read more on that here . Your link is referring to ancient Java versions.
