private InputStream getFromJar (String jarFile, String sharedLibrary) throws IOException {
  ZipFile file = new ZipFile(nativesJar);
  ZipEntry entry = file.getEntry(sharedLibrary);
  return file.getInputStream(entry);
}

代码示例来源：origin: stackoverflow.com

public static void main(String[] args) throws IOException {
  ZipFile zipFile = new ZipFile("C:/test.zip");

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

  while(entries.hasMoreElements()){
    ZipEntry entry = entries.nextElement();
    InputStream stream = zipFile.getInputStream(entry);
  }
}

    if (accept(current)) {
      return zipFile.getInputStream(current);
    }
  }
  // no more entries in this ZipFile, so close ZipFile
  try {
    // zipFile is never null here
    zipFile.close();
  } catch (IOException ex) { // SUPPRESS CHECKSTYLE EmptyBlockCheck
    // suppress IOException, otherwise close() is called twice
  }
  return null;
}
