Question

I have an abstract class Medium, where one of the datamembers is an enum.

private Taal talenOndertiteling[];

public enum Taal {
    NEDERLANDS, FRANS, DUITS, ENGELS, SPAANS, ITALIAANS
}
public Taal[] getTalenOndertiteling() {
    return talenOndertiteling;
}

public void setTalenOndertiteling(Taal[] talenOndertiteling) {
    this.talenOndertiteling = talenOndertiteling;
}

Now when I try to call the last method like this:

            BD bd1 = new BD();
            bd1.setTalenOndertiteling(Taal.ENGELS);

I’m getting an error. (The BD class implements the Medium class) Any ideas on how I should be calling the method? And what if I wanted to set several languates, how would I do that?

Thanks!

Answer 1

Your method accepts a Taal[] but your invocation passes a Taal. You have two choices:

Either pass an explicit Taal[]:

bd1.setTalenOndertiteling(new Taal[] {Taal.ENGELS});

or, change the method declaration to take a vararg parameter and have the compiler do it for you:

public void setTalenOndertiteling(Taal... talenOndertiteling) {
