Question

I would like to omit creating File. My DataHandler Object contains zip file with one entry inside. I need to get properly InputStream which could read zipped content.

Actually, my “flow” is as following: DataHandler -> File -> ZipFile -> first ZipEntry.getInputStream().

Is there a way to not create File/ZipFile object?

Answer 1

Solution is:

DataHandler dh = ... 
ZipInputStream zis = new ZipInputStream(dh.getInputStream());
ZipEntry entry = zis.getNextEntry();

…and after that zis is currently set at the beggining of first zip entry.

Thanks to @aetheria & @Janoz for ZipInputStream hint.
