Delete Branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Für das Programm
import java.lang.Integer;
public class Overloading_Generics {
}
class Overloading_Generics1 {
main(x) {
var olg = new Overloading_Generics();
return olg.id(x);
}
}
klappt der Aufruf olg.id(x); nicht, da die Typen nicht identisch sind.
Problem in Methode areEquals. areEquals prüft nur auf Gleichheit müsste aber auf Instanz prüfen.
Mit match Funktion aus unify versuchen.

olg
so funktioniert es auch nicht
import java.lang.Integer;
public class Overloading_Generics {
}
class Overloading_Generics1 {
main(x) {
var olg = new Overloading_Generics();
return olg.id(1);
}
}
