How to override an interface method with no arguments in a class? (what's the bug)

Question

In short, what is a possible solution if I can't override this method?

I have tried removing the argument and instantiating at the begging with a constructor.

//////Cannot edit this//////
/**
 * Scan interface
 */
interface Scan {
    /**
     * Scan a document
     */
    public void scan();
}
//////Cannot edit this//////

//////Can Edit//////////////
/**
 * HomeScanner class
 */
class HomeScanner implements Scan {
/**
 * Prints "Scanning..."
 */
public void scan() {
    System.out.println("Scanning...");
}

/**
 * Prints what is bieng scanned
 * @param isDoc tells if item being scanned is a document
 */
@Override
public void print(boolean isDoc) {
    if(isDoc) {
        System.out.print("Document ");
    } else {
        System.out.print("Book ");
    }
    scan();
 }
}
//////Can Edit//////////////

After I create the class object I want to be able to call the method with the argument or an alternative with the same outcome.

What is the @Override above the print method for? Why don't you remove that one? – Knokko Just needed to remove it. Thanks!
