try {

zos = new ZipOutputStream(fos);
ZipEntry ze= new ZipEntry("sandeep_cv_blue_zip.doc");//output folder
zos.putNextEntry(ze);
//input file to compress
FileInputStream in = new FileInputStream("D:\MyDocuments\Resume\sandeep_cv_blue.doc");
int len;
//reading
while ((len = in.read(btempBuffer)) > 0) {
zos.write(btempBuffer, 0, len);
}
in.close();
} catch (ZipException e) {
e.printStackTrace();
