 * 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>
