Unzipping a file from InputStream and returning another InputStream

Question

I am trying to write a function which will accept an InputStream with zipped file data and would return another InputStream with unzipped data.

Answer 1

If you can change the input data I would suggested you to use GZIPInputStream.

GZipInputStream is different from ZipInputStream since you only have one data inside it. So the whole input stream represents the whole file. In ZipInputStream the whole stream contains also the structure of the file(s) inside it, which can be many.
