List of Questions5 questions
- Question 1
- A class should only have one responsibility and one reason to change
- A class should handle both data storage and user interface
- A class should have no responsibility to avoid complexity
- A class should have multiple responsibilities to enhance functionality
- Question 2
- Software entities should be open for extension but closed for modification
- Software entities should be open for modification at any time
- Software entities should be closed for extension but open for modification
- Software entities should not be extended to avoid complexity
- Question 3
- Subclasses should not inherit from superclasses
- Objects of a subclass should be substitutable for objects of the superclass without affecting program correctness
- Objects of a subclass cannot be used in place of objects of the superclass
- Subclasses should always override methods of the superclass
- Question 4
- Clients should not implement interfaces to avoid complexity
- Clients should depend on all available interfaces for robustness
- Clients should not be forced to depend on interfaces they do not use
- Clients should implement all available interfaces for flexibility
- Question 5
- Low-level modules should not depend on high-level modules; abstractions are unnecessary
- Modules at any level can depend directly on external libraries
- High-level modules should not depend on low-level modules; both should depend on abstractions
- Modules at any level should directly depend on each other without abstractions
