            byte[] buf = new byte[1024];

            zip.putNextEntry(new ZipEntry(path + "/" + folder.getName()));
            while ((len = in.read(buf)) > 0) {
                zip.write(buf, 0, len);
            }
        }
    }
}

Call : Zip.zipFolder(folderpath);
output : folderpath.zip will be created.
Example: if zipFolder="F:/Testing";
Output :F:/Testing.zip

Alternative : Download Zip.jar

a. Add to project library folder
b. import zip.Zip; in ur program;
c. Call : Zip.zipFolder(folderpath);
output : folderpath.zip will be created.
Example: if zipFolder="F:/Testing";
Output :F:/Testing.zip
