Is is possible to create an instance of a parameterized class with a string based parameter like this :
String aType = "MyType";
AFoobarType<aType> aClassInstance = new AFoobarType<aType>(){
};
Thank you.

1No, it is not. What are you trying to do? – Sotirios Delimanolis Aug 13 '15 at 15:51

If you know the set of classes which you might create, a Switch statement may be your solution. – CubeJockey Aug 13 '15 at 15:53

@SotiriosDelimanolis This question was just out of curiosity. I'm just trying to see how dynamic could be a class creation. Even with reflection it's still impossible to achieve ? – Joe Aug 13 '15 at 15:57

Yes. Generics are a compile time concept. Reflection operates at runtime. – Sotirios Delimanolis Aug 13 '15 at 15:57

@SotiriosDelimanolis I'm trying to do my stuff at runtime. – Joe Aug 13 '15 at 16:00

1But generics don't work at runtime. Their only benefit is that the compiler can catch type incompatibilities at compile time. The types are erased at runtime. – RealSkeptic Aug 13 '15 at 16:04
