Question

I’m am tottaly lost when coming to regular expressions.
I get generated strings like:

Your number is (123,456,789)

How can I filter out 123,456,789?

Answer 1

String str="Your number is (123,456,789)";
str = str.replaceAll(".*\\((.*)\\).*","$1");                    

or you can make the replacement a bit faster by doing:

str = str.replaceAll(".*\\(([\\d,]*)\\).*","$1");
