Regex to match slash does not work

I want a regex to match these:

/web/search/abc
/web/search/employee/999999999
/web/search/employee/78524152

But not this:

/web/search/employee/123456789

I wrote the following regex for Java, but it does not seem to be working.

/web/search/(?!/(employee/123456789)).*

Can someone tell me the correct regex to do this?

Try the following:

/web/search/(?!(employee/123456789$)).*

The slash was doubled in the negating look-ahead group.

What you tried is : /web/search/(?!/(employee/123456789)) can be represented as

You need to change it as /web/search/(?!employee/123456789) can be represented as

I would say

str.contains("^/web/search/(?!employee/123456789)")

satisfies your requirements.

This is because you double the / in the lookahead. Try with:

/web/search/(?!employee/123456789$).*
