Casting objects with reflection possible?

Question

I have this code:
String className = "com.xyz.MeasurementUnit";
Class provider = Class.forName(className + "Provider");
Object object = context.getContractProxy(provider);The last line returns an object of type object. I must execute the method getIsoId(...) on that object. But to do that, I think I have to cast it first to the object type MeasurementUnitProvider.
Is this possible with reflection? Is it somehow possible to solve what I want to do?

Answer 1

If MeasurementUnitProvider is an interface that is known at compile time, then the cast can be made in the usual way MeasurementUnitProvider unitProvider = (MeasurementUnitProvider)context.getContractProxy(provider);If the interface is not known at compile time, then the object reflecting the method can be obtained from the Class object by name and parameter type. For reflective method invocation, no cast is required.
