Hi,

There is a nice article (http://www.javaworld.com/javaworld/jw-10-2001/jw-1005-java101-p2.html) that discusses the four type of polymorphism:

coercion, overloading, parametric and inclusion (subtype).

The article states that (in 2001) Java only supported three types, not including parametric.

The article suggests that Java 1.5 would include support for parametric polymorphism.

My question, does it? If so any examples? If not, is it scheduled?

Cheers,

Simon.

Because this is a general question about Java rather than a question specific to SCJP I am moving it to Java In General (Intermediate).

Getting someone to think and try something out is much more useful than just telling them the answer.

And the short answer: yes.

The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
