What is the trick to get ReplaceAll to Work

[Steve Dyke]

The string I am testing is:

FINISH IS^ SCRATCHED.

But the string remains unchanged.

int i = 0;
while(rs.next()){
	this.rejectionNoteArray[i] = rs.getString(1).trim().replaceAll("^", "\r\n");
								
	i++;
}
rs.close();

What are you trying to do?. Split the line ?

"^" is a special character when it comes to regular expressions (which is what replaceAll does) - it needs to be escaped: try "\\^" instead.

The first argument in replaceAll is a regex pattern and ^ is a special character in regex. You should escape it.

No. When the record is created the user inputs the data into a textarea field. This allows them to use carriage returns and line feeds. Before the data is stored in the database, since the characters used to do the carriage return and line feed is difficult to store I replace these with the '^' character. Now when the data is pulled to be displayed I need to put the carriage returns and line feeds back in where ever a '^' occurs.

Thanks again. Works great.

That make sense. Althought there is a blank space between ^ and SCRATCHED. So you will have like a TAB in the next line.

How are CRLFs difficult to store?! Storing them is no different than storing any other character. And what if there's a caret in the text?
