本文整理了Java中org.apache.tools.zip.ZipFile类的一些代码示例，展示了ZipFile类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ZipFile类的具体详情如下：
包路径：org.apache.tools.zip.ZipFile
类名称：ZipFile

ZipFile介绍

[英]Replacement for java.util.ZipFile.

This class adds support for file name encodings other than UTF-8 (which is required to work on ZIP files created by native zip tools and is able to skip a preamble like the one found in self extracting archives. Furthermore it returns instances of org.apache.tools.zip.ZipEntry instead of java.util.zip.ZipEntry.

It doesn't extend java.util.zip.ZipFile as it would have to reimplement all methods anyway. Like java.util.ZipFile, it uses RandomAccessFile under the covers and supports compressed and uncompressed entries. As of Apache Ant 1.9.0 it also transparently supports Zip64 extensions and thus individual entries and archives larger than 4 GB or with more than 65536 entries.

The method signatures mimic the ones of java.util.zip.ZipFile, with a couple of exceptions:

  • There is no getName method.
  • entries has been renamed to getEntries.
  • getEntries and getEntry return org.apache.tools.zip.ZipEntry instances.
  • close is allowed to throw IOException.
    [中]替换java.util.ZipFile。
    这个类增加了对UTF-8以外的文件名编码的支持（UTF-8是处理本机ZIP工具创建的ZIP文件所必需的，并且能够跳过像在自解压归档文件中找到的前导。此外，它还返回org.apache.tools.zip.ZipEntry而不是java.util.zip.ZipEntry的实例。
    它不会扩展java.util.zip.ZipFile，因为它无论如何都必须重新实现所有方法。与java.util.ZipFile类似，它在封面下使用RandomAccessFile，并支持压缩和未压缩的条目。从ApacheAnt 1.9.0开始，它还透明地支持Zip64扩展，因此单个条目和归档文件的容量大于4GB或超过65536个条目。
    方法签名模仿java.util.zip.ZipFile的签名，但有几个例外：
    *没有getName方法。
    *条目已重命名为getEntries。
    *getEntries和getEntry返回org.apache.tools.zip.ZipEntry个实例。
    *close允许抛出IOException。
