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.

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.

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 :mad:
