It has taken a few days to try, redo, restudy, try, redo, restudy repeatingly until just now ... after taken a corn and some snack ....
Here's a sample code ... of course I found the original code from google, and change here and there to get it work.
There are still a lot of things to learn and explore ... am trying to develop my own Project Scheduling Software ... I have started with Java 1.7, but found some bugs that reduce my confidence on it ... so try Python. Although it seems to be easier in syntax, but there are many ways for getting it work as per expected. But, still enjoy the problems ....
