Class ZipOutputStream
java.lang.Objectjava.io.OutputStream
- All Implemented Interfaces:
- java.util.zip.ZipConstants
- Direct Known Subclasses:
- JarOutputStream
- public class ZipOutputStream
- extends DeflaterOutputStream
- implements java.util.zip.ZipConstants
This class implements an output stream filter for writing files in the ZIP file format. Includes support for both compressed and uncompressed entries. 该类实现了针对写入ZIP文件格式的文件的输出流过滤，包括支持压缩和解压项。
