Giriş
Şu satırı dahil ederiz.

import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;

constructor - File
Örnek
Şöyle yaparız.

ZipFile zipFile = new ZipFile(pathToFile.toFile());

Örnek
Şöyle yaparız.

URL zipUrl = Main.class.getResource("/resources/zipfile.zip");
File zipFile = new File(zipUrl.toURI());
ZipFile zip = new ZipFile(zipFile);

entries metodu
ZipEntry dizisi döner. Girdilere erişmemizi sağlar. Şöyle yaparız.

ZipFile zipFile = ...
Enumeration<? extends ZipEntry> entries = zipFile.entries();

while (entries.hasMoreElements()) {
  ZipEntry entry = entries.nextElement();
  ...
}

getFileHeaders metodu
FileHeader dizisi döner. Açıklaması şöyle.

The end of a Zip file is indicated by the end of central directory record (EOCD). The length of the EOCD is variable because it can contain a comment up to 65535 bytes long. See the bold part of the EOCD layout below:

EOCD şöyledir

+---------+--------+--------------------------------------------------------------------+
| Offset  | Bytes  |                            Description                             |
+---------+--------+--------------------------------------------------------------------+

size metodu
Kaç tane girdi (dosya veye dizin) olduğunu döndürür. Şöyle yaparız.

if (zipFile.size() != 1) {...}
