multiple inheritance

Posted by Sunitha on May 31, 2000 at 7:35 PM

As you may be aware Java does not support multiple inheritance.
When using abstract classes you need your class to inherit from
the abstract class. Since you can inherit from one class only,
it limits the scope for your design.

Java supports multiple inheritance by using interfaces. Interfaces
have to have all abtract methods ( unlike abstract classes that can
have some concrete methods). A class can implment a number of
interfaces thus giving a sort of multiple inheritance.
