Study Notes
Package Cohesion Principles
- There are two principles of package cohesion: the Common Closure Principle (CCP) and the Common Reuse Principle (CRP).
Common Closure Principle
- The Common Closure Principle aims to group classes that are likely to change together in the same package.
- It focuses on minimizing the work to rebuild, test, and deploy a release.
Common Reuse Principle
- The Common Reuse Principle is focused on grouping classes that are used together in the same package.
