A class diagram for the Nokia simulator is a visual representation of the structure of the simulator, using classes as the main building blocks. It shows each of the classes in a hierarchical manner, with arrows indicating relationships between each class, such as association and inheritance. It's common to use shapes to represent classes and arrows to signify relationships between them. The class diagram can then be used by software engineers during development when designing the architecture of their applications. Use EdrawMax to download this template.
