how to zip a folder itself using java

Question

Suppose I have the following directory structure.

D:
eportsjanuary

Inside january there are suppose two excel files say A.xls and B.xls. There are many places where it has been written about how to zip files using java.util.zip. But I want to zip the january folder itself inside reports folder so that both january and january.zip will be present inside reports. (That means when I unzip the january.zip file I should get the january folder).

Can anyone please provide me the code to do this using java.util.zip. Please let me know whether this can be more easily done by using other libraries.

Thanks a lot...

Have you tried Zeroturnaround Zip library? It's really neat! Zip a folder is just a one liner:

ZipUtil.pack(new File("D:\reports\january"), new File("D:\reports\january.zip"));

(thanks to Oleg ?elajev for the example)
