1.Matching Problem for Object-Oriented Programming Principles.
Match the vocabulary with their definitions.
Review the chapter vocabulary in the Summary.
Divide and Conquer Principle
Dividing a problem or a task into parts
Information Hiding Principle
Designing a class so that it shields certain parts of an object from other objects
Interface Principle
Objects present an interface to other objects to determine how they interact with each other.
Generality Principle
Objects will be designed as generally as possible.
Encapsulation Principle
Each object is a self-contained module with the attributes and actions necessary for its role.
Extensibility Principle
Objects will be designed so that they can potentially be extended.
