To answer this question, we need to understand the concept of method overriding in Java.
In the given code, there are two classes: Dog
and Alsation
. The Dog
class has a static method called bark()
that prints "woof ". The Alsation
class extends the Dog
class and also has a static method called bark()
. However, the Alsation
class does not provide an implementation for the bark()
method.
In the Bark
class's main()
method, two objects are created: woofer
of type Dog
and nipper
of type Alsation
. When the bark()
method is called on woofer
, it will call the bark()
method of the Dog
class, which prints "woof ". When the bark()
method is called on nipper
, it will call the bark()
method of the Alsation
class. Since there is no implementation of the bark()
method in the Alsation
class, it will use the implementation of the bark()
method from the superclass (i.e., Dog
class).
Therefore, the output will be "woof woof ".
Option B) woof woof - This option is correct because it matches the output explained above.
The correct answer is B) woof woof.
