Test program not giving expected result

I have five classes. 2 composition classes,1 aggregation class and 1 dependency class.I have coded all the classes but one of my test program is not giving me the expected result.I have the following classes:
TimeStamp
Interval (composition of 2 TimeStamps)
TimeSheet ( aggregation of many Interval)
Employee (composition of many TimeSheet)
FlexiEmployee (dependecy on Employee)

I have coded all the classes but when I run my test program for the Employee it does not give the details of the TimeSheet class.

Please give an insight of what I should do.

Thanks

Post your code. I have no idea why it's not working, I can't see it from here.

Does this work for any employees?
Hard to provide programming guidance when you only speak in generalities. Please show some example data and your programming.
