Am I implementing a generics-based Java factory correctly?

Question

I don\'t believe I am implementing the factory pattern correctly because the Application class\' createDocument method accepts any class type, not just

Answer 1

You should bound your generic so that it is only using T's that inherit Document. example:

public class Application {
    //Add extends Document after T
    public static  T createDocument(Class documentClass) throws InstantiationException, IllegalAccessException {
        return documentClass.newInstance();
    };
}
