What is the primary goal of implementing the Common Closure Principle?

The primary goal of implementing the Common Closure Principle is to group classes that change together into the same module. This principle is part of the SOLID principles of object-oriented design and emphasizes the importance of cohesion within a module. By ensuring that classes that are likely to be modified together are placed within the same module, it reduces the risk of breaking existing functionality when changes are made. This approach leads to better maintainability and a clear understanding of the relationships between classes.

Grouping classes that share common responsibilities or behaviors helps developers manage dependencies more effectively. When a change is required, it can be executed within a single module without affecting other modules, enhancing code stability and facilitating easier testing.

This principle contrasts with other concepts that might focus on increasing class counts, isolating changes in unrelated modules, or decreasing application size, which do not directly address the cohesion and maintainability goals that the Common Closure Principle aims to achieve.
