Review comment:
The rest of the file is formatted with spaces, this blog looks like
tabs? can you fix that?
Instead of `e.printStackTrace()` use a logger.
More importantly though, how was this the exception triggered? I'm guessing
if `hasNextLine()` returns true, and then `.nextLine()` throws a
`NoSuchElementException`, that's not an error you would want to recover from,
as the stream would have been corrupted? And in this case potentially worse
because we are operating against a String in memory, which means things have
gone severely wrong?
I could be miss understanding something here though, I only took a quick
look.
