To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Compilation succeeds - This option is incorrect because the compilation does not succeed. There are errors in the code.
Option B) Compilation fails due only to an error on line 15 - This option is correct. The error on line 15 is that the constructor for the BufferedWriter
class expects a Writer
object as an argument, not a File
object. Therefore, the code fails to compile.
Option C) Compilation fails due only to an error on line 16 - This option is incorrect. Although the constructor for the BufferedWriter
class expects a Writer
object as an argument, the FileWriter
class is a subclass of Writer
. So, there is no error on line 16.
Option D) Compilation fails due only to an error on line 17 - This option is incorrect. Although the constructor for the BufferedWriter
class expects a Writer
object as an argument, the PrintWriter
class is a subclass of Writer
. So, there is no error on line 17.
Option E) Compilation fails due only to an error on line 18 - This option is incorrect. The code on line 18 is valid. It creates a BufferedWriter
object and passes another BufferedWriter
object as an argument to its constructor.
Option F) Compilation fails due to errors on multiple lines - This option is incorrect. The code fails to compile only due to an error on line 15.
The correct answer is B. Compilation fails due only to an error on line 15. This option is correct because the constructor for the BufferedWriter
class expects a Writer
object as an argument, not a File
object.
