Hi,

I'm working on migrating a C# project to java.

In the C# project I have a factory class holding a dictionary between Type, and a delegate which creates appropriate type.

I expose a generic method:
T Create<T>()

So the user can write:

var someObject = factory.Create<ISomeInterface> ();

The Create method code is something like:

return (T)dictionary[typeof(T)]();

The question is, How can I do something similar in Java (version 7)?

Thanks a lot for anyone who would help!
