To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) 0.0 - This option is incorrect because the variable f
is declared and initialized inside the try
block and is not accessible outside the try
block. Therefore, it cannot be printed in the finally
block.
Option B) Compilation fails - This option is correct. The code will not compile because the variable f
is declared inside the try
block and is not accessible outside the try
block. Therefore, when trying to print f
in the finally
block, a compilation error will occur.
Option C) A ParseException is thrown by the parse method at runtime - This option is incorrect because the code does not handle a ParseException
. Instead, it catches a NumberFormatException
in the catch
block.
Option D) A NumberFormatException is thrown by the parse method at runtime - This option is incorrect because the code does not throw a NumberFormatException
. Instead, it catches a NumberFormatException
in the catch
block.
The correct answer is B. Compilation fails because the variable f
is declared inside the try
block and is not accessible outside the try
block.
