To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) foofoofoofoofoo - This option is incorrect. The output will not consist of repeated "foo" values throughout.
Option B) foobarfoobarbar - This option is incorrect. The output will not consist of repeated "foobar" values throughout.
Option C) foobarfoofoofoo - This option is incorrect. The output will not consist of the sequence "foobar" followed by "foo" repeated three times.
Option D) foobarfoobarfoo - This option is correct. The output will consist of the sequence "foobar" followed by "foobar" again, and then "foo".
Option E) barbarbarbarbar - This option is incorrect. The output will not consist of repeated "bar" values throughout.
The correct answer is Option D. This option is correct because the output will be "foobarfoobarfoo".
Explanation:
- The
Base.FOO
will print "foo" since it is a static final variable in the Base
class.
- The
Sub.FOO
will print "bar" since it is a static final variable in the Sub
class.
- The
b.FOO
will print "foo" since it is accessing the FOO
variable from the Base
class using an instance of the Base
class.
- The
s.FOO
will print "bar" since it is accessing the FOO
variable from the Sub
class using an instance of the Sub
class.
- The
((Base)s).FOO
will print "foo" since it is explicitly casting the Sub
instance s
to a Base
instance and accessing the FOO
variable from the Base
class.
Therefore, the output will be "foobarfoobarfoo".
Please select the most appropriate option.
