Class diagrams are fundamental to object-oriented design, providing a blueprint for the system&#8217;s architecture. They help developers visualize the system&#8217;s structure and understand how different components interact. Key Components of Class Diagrams Classes: Represented as rectangles divided into three sections: the top section for the class name, the middle section for attributes, and the bottom section for operations (methods). Attributes: Characteristics or properties of a class, typically listed with their visibility (public, private, protected), type, and default values. Operations: Functions or methods that define what actions can be performed on the class. Relationships: Various types of associations between classes, including: Association: A general connection bet"}
