Given that /green.txt and /colors/yellow.txt are accessible, and the code fragment:
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?
The green.txt file is moved to /colors/yellow.txt atomically, which means the operation is carried out as a single unit of work without interfering failures. After this, the system attempts to delete the source file green.txt. However, since the file has already been moved and thus no longer exists at the original location, a NoSuchFileException will be thrown.
ATOMIC_MOVE prevents FileAlreadyExistsException to be thrown. delete method will cause an Exception since the file is already removed by the atomic move action. Answer is B
