PKWARE-APPNOTE-6.3.9.txt states: 4.3.14 Zip64 end of central directory record ... total number of entries in the central directory 8 bytes
4.3.16 End of central directory record: ... total number of entries in the central directory 2 bytes Yet the list to keep track of those entries in ZipFile is a LinkedList: private final List<ZipArchiveEntry> entries = new LinkedList<>(); Would it not be more efficient with an ArrayList whose initial capacity matches the total number of entries stated in the end of directory record? Assuming the total number of entries <= Integer.MAX_VALUE – 8 of course (see https://www.baeldung.com/java-arrays-max-size). This would also open the way for adding an option to have the ZipFile entry list sorted *in-place* in physical order, which eliminates the needs to allocate yet another large array in getEntriesInPhysicalOrder when dealing with zip files containing many entries. -- Sent with Tutanota, the secure & ad-free mailbox.
