Running java program one after the other

Question

What i have completed:

upload it to server
download from server

download should happen only if upload is done. I have the code to do it as separate java classes. What i need to do is.

For every hour upload should be done in the 1st half hour and only if upload is done , in the next 1/2 hour download should be done.and again after download upload should be done.

use a FLAG , set it to COMPLETE when UPLOAD is done , in download program check for FLAG , if COMPLETE only then begin downloading , else do nothing — Satya, Sep 02 '13 at 08:26
