Constraints in interface implementation in java [duplicate]

Question

Possible Duplicate:
Java generics constraint require default constructor like C#

I want to set a constraint to type T that it must have a constructor without parameters. In C# it will be like:

public interface Interface<T> where T : new() { }

Is this feature available in Java?

Update: Is there some trick to make generic type T have a constructor?

Answer 1

You cannot define interface for constructors in Java. Nor you cann put any other constraints to type parameters, other than type variance.
