Tip: Refactor Mercilessly

• Refactor using design patterns (see Gamma et al., “Design Patterns”).

  • Extract complicated method into Strategy class.
  • Describe creation process with Factory Method.

• Refactor using standard refactorings (see Fowler, “Refactoring”)

  • - Extract code block into separate method.
  • - Replace local variable with query method.
