How to obtain the last path segment of a URI

java, string, url

Solution

is that what you are looking for:

URI uri = new URI("http://example.com/foo/bar/42?param=true");
String path = uri.getPath();
String idStr = path.substring(path.lastIndexOf('/') + 1);
int id = Integer.parseInt(idStr);

alternatively

URI uri = new URI("http://example.com/foo/bar/42?param=true");
String[] segments = uri.getPath().split("/");
String idStr = segments[segments.length-1];
int id = Integer.parseInt(idStr);

Problem

I have as input a string that is a `URI`. how is it possible to get the last path segment (that in my case is an id)? This is my input URL: ``` String uri = "http://base_path/some_segment/id" ``` and I have to obtain the id I have tried with this: ``` String strId = "http://base_path/some_segment/id"; strId = strId.replace(path); strId = strId.replaceAll("/", ""); Integer id = new Integer(strId); return id.intValue(); ``` but it doesn't work, and surely there must be a better way to do it.
