\A
is the beginning of the string. It differs from ^
in that most regex implementations ^
matches after line breaks as well, while \A
does not.
\a
is the bell character.
Question
I was viewing this answer and I noticed that the delimiter was set to \\A
, which is a beep, right? Why is a beep used in the InputStream
? I'm still pretty fuzzy on what a beep even is (Isn't is just for a literal beep?), so I am quite confused as to why it's used as the delimiter, here.
