ZIP fayl tarkibiga kirish

• Java 7-ning FileSystem API fayl tizimidagi Java NIO fayl API-si yordamida Zip faylidan yoki unga yozuvlarni oʻqish va qoʻshish imkonini beradi.
• boshqa fayl tizimida ishlash kabi.
• FileSystem - bu foydalanishdan keyin to'g'ri yopilishi kerak bo'lgan resurs, shuning uchun resurslarni sinab ko'rish bloki
• foydalanilsin.
• Mavjud fayldan o'qish
• Path pathToZip = Paths.get("path/to/file.zip");
• try(FileSystem zipFs = FileSystems.newFileSystem(pathToZip, null)) {
• Path root = zipFs.getPath("/");
• ... //access the content of the zip file same as ordinary files
• } catch(IOException ex) {
• ex.printStackTrace();
• }

Creating a new file
Map env = new HashMap<>();
env.put("create", "true"); //required for creating a new zip file
env.put("encoding", "UTF-8"); //optional: default is UTF-8
URI uri = URI.create("jar:file:/path/to/file.zip");
try (FileSystem zipfs = FileSystems.newFileSystem(uri, env)) {
Path newFile = zipFs.getPath("/newFile.txt");
//writing to file
Files.write(newFile, "Hello world".getBytes());
} catch(IOException ex) {
ex.printStackTrace();
}
