Answer:

A file can only be locked out to other users or processes only if it's already open, meaning it's in use as a resource during the time window and therefore it's impossible solving the race condition problem by locking the file during the check-and-use window.

Hence, during the check-and-use process, it's impossible to lock a file.

In conclusion, any lock created can be ignored by the malicious process.

castortr0y [4]

Answer:

Option (e)

Explanation:

Option (e) is the answer. It indicates the exception thrown and displays it. It also indicates the place where the exception was thrown ( at what line of the code the exception was thrown )

Option (b) is false as it doesn't opens a dialogue box about running the program another time or anything. It just terminates because of the unhandled exception.

Option (c) is false as it doesn't saves all the output to a disk file called the "runStackTrace.txt".

Option (d) is false as it doesn't open a dialogue box. The program terminates because of the unhandled exception.
