Study Notes
Software Design Patterns
- The Strategy Pattern includes the elements: Context, Strategy, and Concrete Strategies.
Software Principles
- Occam's Razor is the principle suggesting that 'often the simplest explanation is the best solution'.
- The principle of Keeping Elements in Sync emphasizes elements changing predictably when modified.
- The Single Responsibility Principle dictates that new functionality must be added to a class, with inheritance being a last resort.
- The principle not part of the SOLID principles is the Command Query Separation Principle.
Liskov Substitution Principle (LSP)
- A class adhering to the Liskov Substitution Principle should not throw exceptions when used as a parent class.
- The LSP requires that subtypes must meet the behavioral conditions of their parent types, ensuring seamless substitution.
Open Closed Principle (OCP)
- According to the Open Closed Principle, you should be able to substitute a subclass for a parent class without issues in client code.
Additional Software Design Principles
- The Dependency Inversion Principle offers benefits like testing advantages, lower coupling, and better organization.
- The class Student violates the principle of Dependency Inversion as it should depend on abstractions, not concrete implementations.
