ZipFileSystem is a file system provider that treats the contents of a zip or

JAR file as a java.nio.file.FileSystem.

The factory methods defined by the java.nio.file.FileSystems class can be

used to create a FileSystem, eg:

   // use file type detection

   Map<String,?> env = Collections.emptyMap();

   Path jarfile = Paths.get("foo.jar");

   FileSystem fs = FileSystems.newFileSystem(jarfile, env, null);

-or

   Map<String,?> env = Collections.emptyMap();

   FileSystem fs = FileSystems.newFileSystem(uri, env);

Once a FileSystem is created then classes in the java.nio.file package

can be used to access files in the zip/JAR file, eg:

   Path mf = fs.getPath("/META-INF/MANIFEST.MF");

   InputStream in = mf.newInputStream();
