Class.getConstructor().newInstance() problem!!

Question

Hi all,
I would like to dynamically create an object using the Class.getConstructor(). newInstance() methods. I store the constructors in a hashtable, and dynamically decide which constructor to call at runtime.
But now I am facing a problem of casting my results. It always return a java.lang.Object, and I'll have to explicitly cast it into the desire class.
Is there any way to avoid these static casting problems? I have the required class name passing dynmically, but now I cannot even compile due to the static casting error..
thanx.

Hello,
The purpose of reflection is to be able to manipulate classes and objects dynamically. Therefore, logically (in the application that you have described ) you would be potentially dealing with different classes. However, it is recognized that you need to invoke some method. My suggestion would be to implement an interface (as you will potentially not know the class) or use the Method (of a particular signature and name) object to invoke it. Static casting goes against the grain of dynamic creation.
