    Templates in Java

    The upcoming Java 5.0 (1.5.0) has support for templates. They are different from the templates in C++ though, but they look quite similar.

    http://java.sun.com/j2se/1.5/pdf/generics-tutorial.pdf

    I think this is a great addition to the/any language, whether you like it or not (let's not start a flame war on Java).

    I've skimmed though the article and have one question:
    Code:
    //Templated classes are written like this:
    public interface Test<T>
    {
      ...
    }
    //But templated methods are written like this
    public <T> int test(T t)
    {
      ...
    }
    Why not test<T>?

    >Why not test<T>?
    I would wager because it's more difficult to parse for methods.
    My best code is written with the delete key.

    then how would you declare the parameter 't'? youd be left with:
    public int test<T> (T t) ... or something....

    Yes, that would be consistent.

    Or if that is too hard to implement for some reason, change the class declaration:
    Code:
    public <T> interface Test{
      ...
    }

    yeah, i like that suggestion better.... now, if only java was open source (as it should be) these things would have been avoided early on in the development stages; damn Sun
