Question

In Java, the URI class is immutable.

Here’s how I’m currently modifying the port:

public URI uriWithPort(URI uri, int port) {
    try {
        return new URI(uri.getScheme(), uri.getUserInfo(), uri.getHost(), port,
                       uri.getPath(), uri.getQuery(), uri.getFragment());
    } catch (URISyntaxException e) {
        LOG.error("Updating URI port failed:",e);
        return uri;
    }
}

Is there a simpler way?

No, that’s pretty much it. ‘Tis a bit verbose, granted, but it’s not that complicated. 🙂

If you’re using Java EE rather than just the JDK, see Talha Ahmed Khan’s answer, which uses Java EE’s UriBuilder, which is still a one-liner but more elegant. That’s not part of the JDK, but if you’re doing a servlet or similar (or don’t mind including the necessary jar)…
