Typically, this would only be necessary if it is not possible to cast an instance of the class to the desired type in non-reflective code. Methods are invoked with java.lang.reflect.Method.invoke. java.lang.Class is the entry point for all the reflection operations.

I Generics sono stati introdotti a partire dalla versione J2SE 5, il termine ha un significato di tipo parametrizzato. I tipi parametrizzati rivestono particolare importanza perché consentono di creare classi, interfacce e metodi per i quali il tipo di dato sul quale si opera può essere specificato come parametro. 08/05/2017 · In this quick article, we've seen how to call instance and static methods of a class at runtime through reflection. We also showed how to change the accessible flag on the reflected method objects to suppress Java access control checks when invoking private and protected methods.
