Question

I have one class called HyperlinkEventMonitor that implements a HyperlinkListener. I want to extend this class so that it handles both hyperlink events and mouseevents. I tried creating a superclass but I’m not doing this right because I can’t compile the code. Can someone show me how to do this.

For example: I tried

class    MouseHyperLink extends HyperlinkEventMonitor, implements MouseListener {

}

But this is wrong.

How can I do this?

Thank you,

Elliott

Without further information on the error message I’ll guess that it is the comma-character that messes things up. Try removing the comma-character:

class MouseHyperLink extends HyperlinkEventMonitor implements MouseListener {
    // ...
}

Also, make sure that you implement all methods of MouseListener.

If you don’t want to implement all methods in MouseListener (and defer that to the subclass) you’ll have to make the class abstract:

abstract class MouseHyperLink extends HyperlinkEventMonitor
                              implements MouseListener {
}
