Need help!! Example of a simple program used for business!

paulymonz · #1 (**permalink**) January 9th, 2012, 05:47 AM

can anyone give me some examples of programs using JOption which are somehow similar to cashier register or programs used for registration of students or others. They should have the function to add, subtract, delete, update, and can be stored. I need it as an example for our module in our project proposal and project defense.. hope u can help me out..

tnx.. =>
