Does Java support virtual functions?
--------------------------------------------------------------------------------
No, Java does not support virtual functions directly as
supported by C++. Virtual functions can be implemented in Java
using abstract classes and interfaces. Abstract class is a class
with declaration of methods, but without their implementation.
The implementation of the methods takes place in the subclasses.
Another example of virtual functions is interfaces. The only
difference between an abstract class and an interface is that
abstract classes can be used only when they are superclasses and
the subclass implements their methods. Whereas in an interface
the methods can be implemented even by classes, which are not
inherited.
