Visual paradigm

Going forward we will be drawing diagrams to design & document code.

Download visual paradigm and use the following academic license by following this guide:

Three steps to improve code quality and document changes:

Exercise 1 - Document program:

  • Finish the diagram such that it documents the Crypto Converter program: [system-sequence-diagrams.md](../../topics/03 - programflow/system-sequence-diagrams.md)

Exercise 2 - Refactor code:

  • Implement error handling as a try/catch in your Crypto Converter

  • If the user enters input that does not contain numbers

    • Handle the exception by informing the user of wrong input and ask the user for input again

Exercise 3 - Update documentation:

  • Update the documentation such that the newly refactored code is documented

  • This can be modelled as an alt scenario:

Extra Credit: NemId Authorizer

Create a method called ”NemIdAuthorizer”.

NemIdAuthorizer returns a boolean value.

isValidInput receives two parameters: String cpr & String password.

  • If cpr does not adhere to a valid cpr number - the method will throw a new InputMismatchException

  • If InputMismatchException is thrown - the program will inform the user and request another input

Extra Extra Credit: Google Interview question

Ask in class if you want a challenge Google uses in their interview process
