Classification of Design Patterns
As mentioned in the previous chapter, design patterns are typically divided into three categories:
- Creational Patterns: Concerned with the way of creating objects.
- Structural Patterns: Deal with object composition and typically identify simple ways to realize relationships between entities.
- Behavioral Patterns: Concerned with effective communication and the assignment of responsibilities between objects.
The flowchart below visually outlines a decision-making process for selecting design patterns such as Factory, Abstract Factory, Singleton, Prototype, Adapter, Composite, Proxy, and others. The chart begins with a central decision point and branches out based on certain criteria, leading to the selection of an appropriate design pattern.

Build the mental picture, not memorization.
I just read a lesson on **Classification of Design Patterns** (OO & Low-Level Design) and want to truly understand it. Explain Classification of Design Patterns from first principles using ONE vivid real-world analogy and a visual mental model — draw it as ASCII art or a clear step-by-step diagram — with a concrete example using real numbers. Then ask me one question to check I got the mental picture, and wait for my reply. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
Socratic — adapts to where you're stuck.
Teach me **Classification of Design Patterns** interactively. Ask me ONE guiding question at a time, wait for my answer, and adapt to my confusion — build the idea with me step by step instead of explaining it all at once. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
Active recall exposes what you missed.
Quiz me on **Classification of Design Patterns** with 5 questions, easy to tricky, ONE at a time. Tell me if each answer is right; at the end, explain clearly what I got wrong and why. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
Intuition + hook + flashcards for long-term memory.
Help me remember **Classification of Design Patterns** for the long term: give the one-sentence intuition, a memorable hook/mnemonic, a tiny worked example, and 3 active-recall flashcards (Q -> A). If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
