How to compress a String in Java?

Question

I use GZIPOutputStream or ZIPOutputStream to compress a String (my string.length() is less than 20), but the compressed result is long

Answer 1

You don't see any compression happening for your String, As you atleast require couple of hundred bytes to have real compression using GZIPOutputStream or ZIPOutputStream. Your String is too small.(I don't understand why you require compression for same)

Check Conclusion from this article:

The article also shows how to compress and decompress data on the fly in order to reduce network traffic and improve the performance of your client/server applications. Compressing data on the fly, however, improves the performance of client/server applications only when the objects being compressed are more than a couple of hundred bytes. You would not be able to observe improvement in performance if the objects being compressed and transferred are simple String objects, for example.
