Given the code fragment:

and assuming that the file /data/december/log.txt is accessible and contains:

10-Dec-2014 – Executed successfully

What is the result?

A. A file with the name log.txt is created in the /data directory and the content of the /data/december/log.txt file is copied to it.
B. The program executes successfully and does NOT change the file system.
C. A FileNotFoundException is thrown at run time.
D. A FileAlreadyExistsException is thrown at run time.


若/data已存在,程式會拋出FileAlreadyExistsException。若/data不存在,會在「/」目錄下產生「data」檔案,內容為「10-Dec-2014 – Executed successfully」。
