Menetelmäluokkia

Menetelmäluokkia, a Finnish term, translates to "method classes" or "procedure classes" in English. In the context of programming and software design, it refers to a category of classes that primarily encapsulate a collection of related methods or functions. Unlike data classes that focus on holding and organizing data, method classes are designed to perform actions or operations. They often represent behaviors or functionalities that can be applied to certain types of data, even if they don't directly own that data themselves.

The concept of method classes is closely related to object-oriented programming principles, particularly encapsulation and abstraction. By grouping related methods within a class, developers can improve code organization, reusability, and maintainability. This approach helps in separating concerns, making it easier to understand and manage different parts of a software system. For instance, a `FileHandler` class might contain methods for reading, writing, and deleting files, embodying the procedures associated with file operations.

While object-oriented languages often promote placing methods within the classes of the objects they operate on, method classes can also serve as utility classes or service classes. These classes might provide static methods or instance methods that operate on external data structures or perform general-purpose tasks. The decision to use a method class, as opposed to other design patterns, depends on the specific requirements and the overall architecture of the software being developed.
