Question

I would like to implement another interface in this interface (Ifirst). Problem is very big because they are blocked and is not possible to write “implements Isecond” Maybe you know what I have to do to implement this in another way? Because this problem is very hard of course look easy but is really difficult.

public interface Ifirst {

}

public interface Isecond {

}

They are blocked and I can use them but I`am not able to edit.

I get answ – > Create a third that extends first and second and don’t add anything to it

I get correct answer, maybe is not the best way but is working. I gave you points for help Topic [closed] “Create a third that extends first and second and don’t add anything to it.”

Answer 1

Interfaces can’t use implements, the rule is:

• An interface extends other interfaces.
• A class implements other interfaces.
• A class extends another non-final class.

If you can’t modify Ifirst and Isecond, that’s the way.

public interface Ithird extends Ifirst, Isecond {

}
