Code smell

• Code duplication

• Feature envy

  • Method makes multiple calls to methods and attributes of another class, which means that the method isn't in the right class
  • Solution
    • Move the method, or some part of the method to the right class

• God class (Winnebago)

  • Class with a lot of attributes and dependencies to other classes. It's du to the fact that we're able to design a correct architecture for the code
  • Solutions
    • Divide and rule
    • Use abstract classes

• Large class

• Long method

• Long parameter list

  • Solutions
    • Remove parameters that resulted from the call to another objet and use the objet as parameter
    • Group the parameters which could form a separate method

• cyclomatic complexity
