The
implements keyword allows classes to
|
|
|
“derive”
from a completely abstract class or to
|
|
|
“implement”
the code for a pure abstract class
|
|
|

The
implementation becomes an ordinary class
|
|
which
can be extended in the regular way
|
|
|

Except
that members must all be defined as
|
|
|
public
|
|
|
|
interface
list { void display(); }
|
|
|
|
class
ordered_list implements list {
|
|
|
Public
void display();}
