Why should I care that Java doesn't have reified generics?
...ic Foo() {
this.t = new T(); // Help?
}
}
This does work in C# assuming that T has a default constructor. You can even get the runtime type by typeof(T) and get the constructors by Type.GetConstructor().
The common Java solution would be to pass the Class<T> as argument.
