Re: Selbstdefinierte Datenklasse als Array

Hallo,
ich habe ein Problem. Ich möchte eine selbstdefinierte Datenklasse,
z.B.
public class Adresse {
String vorname;
String nachname;
String strasse;
int plz;
}
als Array verwenden.
Du möchtest Instanzen dieser Klasse _in_ einem
Array ablegen. Bei deiner Formulierung müsste
Adresse die Klasse Array erweitern.
public static void main() {
Adresse[] adr = new Adresse[5];
adr[1].plz = 27711;
adr[1].vorname = "hans";
}
Schonmal das Wort Datenkapselung gehört?
Btw. ist es keine gute Idee, eine PLZ als
int zu definieren.
Wo ist denn mein Denkfehler?
Du versuchst zu programmieren, ohne Ahnung von den Basics
zu haben - lesen bildet.
