    Class Connections : Depending on the access modifier, each class has a different level of access (visibility). The following are the access levels and the symbols that correlate to them:
    • Public (+)
    • Private (-)
    • Protected (#)
    • Package (~)
    • Derived (/)
    • Static (underlined)

  • Step 2: Determine the targeted users

    After the symbol familiarization, you’ll need to determine your targeted users. Your targeted users will be the ones to use your project.

    The gathered information from the targeted users are very useful in creating an class diagram. You just need to evaluate these data and pick the useful classes. Then you’re ready for the next step.

  • Step 4: Plot the Class Diagram

    To plot the class diagram you will need the class name, its attributes, methods, and their access (visibility). You will base the diagram from the evaluated information to have the exact Class Diagram.

    To plot your Class diagram, you need to place first the classes and their characteristics.

    Then place the visibility of the class’ attributes. You will declare their visibility into the project to know their function.

    Finally, put the connections or relation of a class to the other classes to make sure they are working to produce the desired outcome.
