Class — Object-Oriented Programming Reference

Quick-reference skill for OOP concepts, class design, SOLID principles, and common design patterns.

When to Use

  • Designing class hierarchies and choosing inheritance vs composition
  • Applying SOLID principles to refactor code
  • Understanding polymorphism, encapsulation, and abstraction
  • Choosing the right design pattern for a problem
  • Comparing OOP across languages (Java, Python, TypeScript, C++)

    • Commands

    intro

    scripts/script.sh intro

    OOP fundamentals — classes, objects, the four pillars.

    solid

    scripts/script.sh solid

    SOLID principles — SRP, OCP, LSP, ISP, DIP explained with examples.

    inheritance

    Essential design patterns — Factory, Strategy, Observer, Singleton, Builder.

    access

    scripts/script.sh access

    Access modifiers and encapsulation — public, private, protected across languages.

    abstract

    scripts/script.sh abstract

    Abstract classes, interfaces, and protocols — contracts and polymorphism.

    pitfalls
