COVER // HOW WOULD YOU DESIGN AN API FOR A LIBRARY MANAGEMENT SYSTEM THAT UTILIZES OBJECT-ORIENTED PRINCIPLES, AND WHAT CONSIDERATIONS WOULD YOU TAKE INTO ACCOUNT FOR EXTENSIBILITY AND MAINTAINABILITY?

I would start by defining key entities such as Book, Member, and Loan, each as classes with relevant attributes and methods. For extensibility, I would use interfaces or abstract classes, allowing for different types of books or members. Maintainability would be ensured through clear documentation and adherence to SOLID principles.
