Match "_<digit>string" wth a regular expression

I have a list of strings like

So I have a string followed by an underscore and "pathway". There may be a digit between the underscore and "pathway". How can I match and replace everything except xxx with a regular expression in Java?

This does not work:

pathnameRaw = pathnameRaw.replace("_\\dpathway","");

Your regex is almost fine. Since the digit is optional, add a ? at the end of \\d.

Also the replace method does not use regex. Use replaceAll instead.
