Answer Posted / ramavtar rajput
abstract classes and methods. It is not allowed to create an
instance of a class that has been defined as abstract. Any
class that contains at least one abstract method must also
be abstract. Methods defined as abstract simply declare the
method's signature they cannot define the implementation.
When inheriting from an abstract class, all methods marked
abstract in the parent's class declaration must be defined
by the child; additionally, these methods must be defined
with the same (or a less restricted) visibility. For
example, if the abstract method is defined as protected, the
function implementation must be defined as either protected
or public, but not private.
