Question

Difference between creational structural and behavioral patterns

Answer 1

Hi!

Structural patterns are used for defining the static properties of the system (see Class diagram). Example: Factory pattern can be used to create entities which constitute your system. You can have object Button that have different graphical properties on Windows vs. OS X.


Hope it works!!!

Answer 2

Structural patterns define class composition and hierarchy, they mostly care about the "has a" or "knows a" relationship... like the Composite pattern.Behavioral patterns, on the other hand, change the way your classes behave by changing the way they interact with other classes and interfaces, and the way other classes and interfaces interact with them.
