title: Saving Multiple Files to ZIP Without Saving Them & Reading Them Back In
body: <p>I am creating multiple files from String's.</p>
  
  <p>For example 4 strings; one in xml, and 3 csv format.</p>
  
  <p>My question is do I have to first save these String's into a file before then reading it and then writing out to the ZipOutputStream? Just seems like a bit of a waste really.</p>
  
  <p><strong>Thanks in advance</strong></p>
