Hello,
I compress data using GZIPOutputStream. Is there any way to find out the size of the compressed data?
here is what I do
sb ( StringBuffer )has some data...

GZIPOutputStream gzos =
new GZIPOutputStream(response.getOutputStream());
gzos.write(sb.toString().getBytes());
gzos.close();
Kindly let me know.. I need to find out how good the compression is..

Write it to a file and look at the file size?

Create a ByteArrayOutputStream, "Baos".
Use "Baos" in the ctor of the GZIPOutputStream, "gzip".
Use the .write() method of the "gzip" object.
When done writing to gzip object say "Baos.size()". That is the size of your compressed data.
