Method Details
-
putNextEntry
Begins writing a new JAR file entry and positions the stream to the start of the entry data. This method will also close any previous entry. The default compression method will be used if no compression method was specified for the entry. The current time will be used if the entry has no set modification time.- Overrides:
putNextEntry
in classZipOutputStream
- Parameters:
ze
- the ZIP/JAR entry to be written- Throws:
ZipException
