How to check URL format?

Check format of URL

• I need a Java code which accepts an URL like http://www.example.com and displays whether the format of URL is correct or not.

• Answer:

  This should do what you're asking for. public boolean isValidURL(String urlStr) { try { URL url = new URL(urlStr); return true; } catch (MalformedURLException e) { return false; } } Here's an alternate version: public boolean isValidURI(String uriStr) { try { URI uri = new URI(uriStr); return true; } catch (URISyntaxException e) { return false; } }
