What regular expression to find a string that does not contain a substring?

Question

I am working on a simple tool for checking Java coding guidelines for a project. One of these recommendations is to make sure that there is no variable declared as "private static ...", only "private static final ..." is allowed.

I am wondering how I can get this result. I wrote this:

pattern  = "private\\\s*static\\\s*(?!final)";

But it does not work. How can I get only entries without the keyword "final"?

Thanks, Med.

That should work, yes. You might want to move the second white space in the viewport:

pattern = "private\\s*static(?!\\s*final)";
