URI: Uniform Resource Identifier (URI) is a string of characters used to identify a name or a resource on the Internet. Such identification enables interaction with representations of the resource over a network (typically the World Wide Web) using specific protocols URL: In computing, a Uniform Resource Locator (URL) is a subset of the Uniform Resource Identifier (URI) that specifies where an ...
A URI has two specializations known as URL and URN. A Uniform Resource Locator (URL) is a subset of the Uniform Resource Identifier (URI) that specifies where an identified resource is available and the mechanism for retrieving it.
The java.net.URI doc itself says "every URL is a URI, abstractly speaking, but not every URI is a URL". And java.net.URL does weird stuff like checking equality of URLs by resolving host names to IP addresses (which seems at odds with RFC 3986 sec 6 in the first place, and breaks w virtual hosts).
What is the difference between a URI, a URL, and a URN?
In the classical view, a URI is a URL if it specifies the location of a resource, and a URI is a URN if it specifies the name of a resource. In the contemporary view, making this differentiation is not relevant or useful.
