I have started to learn UML and i have some basic questions 1 If a parent class has an attribute or operation specified private. what would a class derived from it be a child class it is can't inherit the private attributes or operation? 2 Isn't use case considered to be a dynamic view? 3) are concurrent states and AND states the same? 4) i have come across the statement a couple of times "The UML model tells what a system is supposed to do. It doesn't tell how" i thought the state diagrams, collboration diagrams do show how the system is supposed to do its task? I would appreciate the help    More>>

2 Isn't use case considered to be a dynamic view?

3) are concurrent states and AND states the same?

4) i have come across the statement a couple of times
"The UML model tells what a system is supposed to do. It doesn't tell how"

1. a child class will not inherit the method/behavior specified as private in parent's class.


2. use case is a dynamic view


3. N/A


4. i am not too sure but the statement that u been reading should be " The Use Case model tells what a system suppose to do.".....use case diagram tells what a system suppose to do, activity and sequence diagram tells u how it is done.....
