Question

Consider the following set up:

 - SomeFilter extends Filter
 - Filter implements Runnable
 - Filter provides run() implementation

Is there a way to make SomeFilter use it’s super‘s run() and bit more?

The logic inside run() is generic enough for

- MyFilter extends Filter
- MyOtherFilter extends Filter

but is not for SomeFilter, that would like to use it’s super’s run() and add a few extra lines of code to handle it’s own specific case?

Is there way to do it, other then for SomeFilter to override run() altogether?

Answer 1

Yes. Inside SomeFilter:

@Override
public void run(){
   super.run();
   // custom run code

}
