Java uri vs url
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. A URL defines how the resource can be obtained.
URI = (Uniform Resource Identifier) The address of an Internet resource. A URI is the unique name used to access the resource. It is not necessarily a specific file location (it may be a call to an application or a database, for example), which is why it is preferred over the similar acronym URL (Uniform Resource Locator). When comparing URI values, a relative URI is always less than an absolute URI, and a non-null URI is always greater than a null URI. For cases where both uri1 and uri2 are not null and are both relative URIs or both absolute URIs, the String.Compare(String, String, StringComparison) method performs the comparison. Applies to The third U –URI – stands for Uniform Resource Identifier, which can be a URL, a URN, or a combination of the two. It is important to note that, while URLs will always serve as URIs, the other way around is not always applicable.

URI (java.net, 1.4) Represents a Uniform Resource Identifier (URI) reference. URI is a (slight) abstraction over URL. The difference between URI and URL is conceptual and mostly academic, but URI is better defined in a formal sense, and covers a wider range of use cases.
The most common form of URI is the Uniform Resource Locator , frequently referred to informally as a web address. More rarely seen in usage is the Uniform Resource Name (URN), which was designed to complement URLs by providing a mechanism for the identification of resources in particular namespaces All three URI, URL, and URN are used to identify any resource or name on the internet, but there is a subtle difference between them. URI is the superset of both URL and URN. By the way, the main difference between URL and URI is protocol to retrieve the resource.
If you have a File object, you can obtain a URI to the file by calling the toURI() method on the file. In general, although the File object has a toURL() method, this method doesn't handle special character conversion, so in general it's best to call toURI().toURL() to get a URL to the file, since this will handle special character conversions.
URL stands for Uniform Resource Locator and it is supposed to be used only for identifiers that point out a location. In the general public, any hyperlink is called a URL even if it is not necessarily a URL. The URI or Uniform Resource Identifier was created as the name for anything that points to a resource.

Dec 14, 2019 · In short, the main difference between a URI and a URL is that the former acts as a resource identify either by location name or both, while the latter acts as the location. Since a URL identifies a resource using one of the URI schemes, it is a subset of URI. As such, a URL is a non-persistent type of the URI.

More rarely seen in usage is the Uniform Resource Name (URN), which was designed to complement URLs by providing a mechanism for the identification of resources in particular namespaces URI/URL is constrained. To be valid it has to follow a certain format. By saying that they only accept a URI/URL methods are saying that the string they accept has to be in that format. This also makes it clearer "at a glance" what the method is expecting (a URL) rather than potentially any String.
