Question 247

/green.txt and /colors/yellow.txt are accessible, and the code fragment:

Given that -

Path source = Paths.get("/green.txt);

Path target = Paths.get("/colors/yellow.txt);

Files.move(source, target, StandardCopyOption.ATOMIC_MOVE);

Files.delete(source);

Which statement is true?

green.txt file content is replaced by the yellow.txt file content and the yellow.txt file is deleted.

The yellow.txt file content is replaced by the green.txt file content and an exception is thrown.

The green.txt is moved to the /colors directory.

The file FileAlreadyExistsException is thrown at runtime.

Correct Answer: A

The yellow.txt file content is replaced by the green.txt file content and an exception is thrown. The move operation succeeds in moving green.txt to /colors/yellow.txt. After the move, the source file (green.txt) no longer exists at its original location because it has been moved. Trying to delete the source file after it has been moved will result in an exception.
