java escape string – for use in url

Question

I want to use a string within a url:

some/url/<mystring>

My problem: mystring comes directly from a user input where it is allowed to type any special character including dangerous ones, like slash for example. I want to escape those.

EDIT: no, I do not want to escape HTML code. I want to escape the parts of a string, that could make the url directing elsewhere than to url/to/{input}. (for example / or ?)

URL-escape then! Be careful, if and when you receive those later on in any of your flows. — x80486, Jun 27 '18 at 16:02

Escape your url with String escapedURL=java.net.URLEncoder(url);
