Meaning of pound (#) in a regular expression

Question

I have a regular expression with a pound # modifier.

What does \\# mean in a regular expression? What does the # mean in a regul

Answer 1

As you have suspected, it's just a mistake.

To be sure, I ran:

String quote = Pattern.quote("_#_");

and the output was:

"\Q_#_\E"

So, clearly, the pound symbol ("#") is not a special character for java regex.

See: Pattern.quote()
