in object oriented design final result is implement the class diagramme in code am i right ?

what is the use of UML diagramms in OOAD?

in object oriented analysis i have seen use these UML diagrams - use case diagram,sequence diagram to create the class diagram
are above diagrams are the only ones that used in analysis(create the class diagramme)?

in object oriented design i have seen used these UML diagrams - class diagram , sequential diagram to used to implement the code(code of the classes)
are above diagrams are the only ones that used in design to implement class diagram in code?

or depending on need other type of UML diagrams are use in object oriented analysis and object oriented design?

Solution

in object oriented analysis final result is the class diagramme of system am i right? No. The result of the analysis is a model that represents the problem domain. Any diagram used is just a means to reflect the model to its readers.

in object oriented design final result is implement the class diagramme in code am i right ? No. The result is an architectural model which is based on the analysis model. You might be able to generate code from this model. At least a coder can take this model to transform it to code.

what is the use of UML diagramms in OOAD? UML diagrams are used to visualize the model of the problem domain. You can live without the diagrams, but they support communication between humans.

You will use different diagram types depending on what part(s) of the model you will shed light on.
