Your question is not very clear... But you should have a look to the java.util.zip package...

EDIT : if you want to use a library, you can also take a look at the apache's commons compress library (at http://commons.apache.org/compress) that allow you to create an ArchiveOutputStream and add your files as ZipEntry (see the example in the javadoc : http://commons.apache.org/compress/apidocs/org/apache/commons/compress/archivers/ArchiveStreamFactory.html)

In a terminal (if your OS is Linux or Mac or you have Cygwin in Windows):

gzip *.zip > newzip.zip
