What is an advantage of having os be of type OutputStream instead of FileOutputStream?
Why is OutputStream declared inside parenthesis, but not inside the try block?
What is the minimum possible value that a byte can have? (It CAN have negative values) (Extra: How about int?)
(Extra) What is the minimum number of bytes that will be found in the file?
