A consolidated Uniform Resource Locator implementation for Java

A Uniform Resource Locator (URL) is a compact representation of the location and access method for a resource available via the Internet.

Historically, there are many different forms of internet resource representations, for example, the URL (RFC 1738 as of 1994), the URI (RFC 2396 as of 1998), and IRI (RFC 3987 as of 2005), and most of them have updated specifications.

This Java implementation serves as a universal point of handling all different forms. It follows the syntax of the Uniform Resource Identifier (RFC 3986) in accordance with the https://url.spec.whatwg.org/[WHATWG URL standard].

This alternative implementation of Uniform Resource Locator combines the features of the vanilla URI/URL Java SDK implementations but removes it peculiarities and deficiencies, such as java.lang.IllegalArgumentException: Illegal character in path at ... at java.net.URI.create()

Normalization, NIO charset encoding/decoding, IPv6, an extensive set of schemes, and path matching have been added.

Fast building and parsing URLs, improved percent decoding/encoding, and URI templating features are included, to make this library also useful in URI and IRI contexts.

While parsing and building, you have better control about address resolving. Only explicit resolveFromhost methods will execute host lookup queries against DNS resolvers, otherwise, no resolving will occur under the hood.

You can build URLs with a fluent API, for example

URL.http().host("foo.com").toUrlString()

And you can parse URLs with a fluent API, for exmaple

URL url = URL.parser().parse("file:///foo/bar?foo=bar#fragment");

There is no external dependency. The size of the jar library is ~118k. The only dependency on java.net are the classes

java.net.IDN
java.net.Inet4Address
java.net.Inet6Address
java.net.InetAddress

which might get re-implemented in another library at a later time, in a project like Netty DNS resolver.
