Looking for class diagram examples and answers

## Class DiagramsClass diagrams are a type of UML diagram that depict the static structure of a system, including its classes, their attributes, methods, and relationships among objects. They are widely used in software engineering for designing and documenting systems.### Class Diagram ComponentsA class diagram consists of the following components:1. **Classes**: These are depicted as rectangles with the class name at the top, followed by the class's attributes and methods.2. **Attributes**: These are the properties of a class, listed in the second part of the class rectangle.3. **Methods**: These are the operations that a class can perform. They are listed in the third part of the class rectangle.4. **Relationships**: These are the connections between classes, represented by lines. There are several types of relationships, including association, aggregation, composition, and inheritance.### Example of a Class DiagramConsider a simple system for a library. We have three classes: `Book`, `Member`, and `Loan`. | Class | Attributes | Methods ||-------|------------|---------|| Book | - title- author- ISBN | - getTitle()- getAuthor()- getISBN() || Member | - name- memberID | - getName()- getMemberID() || Loan | - loanID- issueDate- returnDate | - getLoanID()- getIssueDate()- getReturnDate() |The relationships between these classes could be as follows:- A `Member` can have multiple `Loans` (one-to-many relationship).- Each `Loan` is associated with one `Book` and one `Member` (many-to-one relationship).This would be represented in a class diagram as follows:```Member ------- Loan ------- Book```In this diagram, the `` and `` symbols represent the "one" and "many" sides of the relationships, respectively.### ConclusionClass diagrams are a powerful tool for visualizing and documenting the structure of a system. They can help you understand the relationships between different parts of a system, and they can serve as a blueprint for implementing the system in code.
