Cześć,
Błagam (bo innego słowa już nie mogę użyć bo męczę się z tym pół dnia) o pomoc.
Potrzebuję użyć metody getDeclaredMethods()
Class klasa = [nazwaKlasy].class;
Method[] me = klasa.getDeclaredMethods();
Problem mój jest w tym, że [nazwaKlasy] pochodzi ze Stringa.
Jak temu zaradzić? Tzn jak z zawartości Stringa zrobić obiekt typu [zawartośćStringa]
Pozdrawiam
Adam
Class.forName("com.dupa.Klasa")
Po wstawieniu forName (argumentem poi jest "File":
public String info(String poi) throws ClassNotFoundException, InstantiationException, IllegalAccessException {
//
Class klasa;
klasa = Class.forName(poi);
Constructor<?>[] ko = klasa.getDeclaredConstructors();
Method[] me = klasa.getDeclaredMethods();
Field[] po = klasa.getDeclaredFields();
Field[] po2 = (klasa.getSuperclass()).getDeclaredFields();
Class[] po3 = (klasa.getInterfaces());
Class po4 = (klasa.getSuperclass());
dostaję komunikat o błędzie:

Nie ma klasy o nazwie "File", jest klasa "java.io.File".
