Milliseid disainimustrite klassifikatsioone teate?

The main classifications of design patterns include:

1. By purpose:

   • Creational: Describe ways of creating objects, increasing flexibility and reusability.
   • Structural: Describe ways of combining classes and objects into larger structures.
   • Behavioral: Describe algorithms and distribution of responsibilities among objects.

2. By application area:

   • Class patterns: Describe static relationships between classes, fixed at compile time. Use inheritance to create abstract relationships.
   • Object patterns: Describe dynamic relationships between objects, which can change during execution. Use composition to create links.

For example, the Factory Method pattern is a creational pattern and belongs to class patterns, while the Strategy pattern is a behavioral pattern and belongs to object patterns.
