/**
* Provides the implementation of the Zip file system provider.
* The Zip file system provider treats the contents of a Zip or JAR file as a file system.
* <p>
*
* <h3>Accessing a Zip File System</h3>
*
* The {@linkplain java.nio.file.FileSystems FileSystems} {@code newFileSystem}
* static factory methods can be used to:
* <ul>
* <li>Create a Zip file system</li>
* <li>Open an existing file as a Zip file system</li>
* </ul>
*
* <h3>URI Scheme Used to Identify the Zip File System</h3>
*
* The URI {@link java.net.URI#getScheme scheme} that identifies the ZIP file system is {@code jar}.
*
* <h3>Zip File System Properties</h3>
*
* The following properties may be specified when creating a Zip
* file system:
* <p>
* <table class="striped">
* <caption style="display:none">
* Configurable properties that may be specified when creating
* a new Zip file system
* </caption>
* <thead>
* <tr>
* <th scope="col">Property Name</th>
* <th scope="col">Data Type</th>
* <th scope="col">Default Value</th>
* <th scope="col">Description</th>
* </tr>
* </thead>
*
* <tbody>
* <tr>
* <td scope="row">create</td>
* <td>java.lang.String</td>
* <td>false</td>
* <td>
* If the value is {@code true}, the Zip file system provider
* creates a new Zip or JAR file if it does not exist.
* </td>
* </tr>
* <tr>
* <td scope="row">encoding</td>
* <td>java.lang.String</td>
* <td>UTF-8</td>
* <td>
* The value indicates the encoding scheme for the
* names of the entries in the Zip or JAR file.
* </td>
* </tr>
* </tbody>
* </table>
*
* <h3>Examples:</h3>
*
* Construct a new Zip file system that is identified by a URI. If the Zip file does not exist,
* it will be created:
* <pre>
* {@code
*
* URI uri = URI.create("jar:file:/home/luckydog/tennisTeam.zip");
* Map<String, String> env = Map.of("create", "true");
* FileSystem zipfs = FileSystems.newFileSystem(uri, env);
* }
* </pre>
*
* Construct a new Zip file system that is identified by specifying a path
* and using automatic file type detection. Iterate from the root of the JAR displaying each
* found entry:
* <pre>
* {@code
*
* FileSystem zipfs = FileSystems.newFileSystem(Path.of("helloworld.jar"), null);
* Path rootDir = zipfs.getPath("/");
* Files.walk(rootDir)
* .forEach(System.out::println);
* }
* </pre>
* @provides java.nio.file.spi.FileSystemProvider
* @moduleGraph
* @since 9
