incompatible types?

public void registrer()
{

{
System.out.println("Tabellen er fullt.");
}
else
{ // frithjof
String fornavn = Keyboard.readln("Fornavn: ");

Person P = new Person(fornavn, etternavn, f�dsels�r);

nyPerson[antall] = new ArbTaker(P,nr,ans�r, l�nn, skatteprosent);
antall++;
} // end else

i get this error message :

nyPerson was declared as an array of Person objects. But you are trying to put an ArbTaker object into the array. Unless ArbTaker is a subclass of Person, it won't work.

a small remark:

new ArbTaker(P,nr,ans�r, l�nn, skatteprosent); 

It's not a good idea to use local characters in code.
Though it matches the idea of good readable code perfectly, there are some tradeoffs:
If you move your code to a different platform/ environment, it might not work.
Some filesystems might refuse to use local available characters in filenames.
If you have to ask questions in forums, or share the code with foreign developers, they might be unable, to use your code - at least it will make them headaches, how to input these characters on their keyboards.
As far as I know, local characters don't build 'valid', 'allowed' code due to the language specification, though it might work.
