In the context of LSP, what is meant by 'substitutability'?
The ability to change the behavior of a superclass by modifying its subclass.
The idea that all methods in a subclass should be static.
The practice of always using abstract classes instead of concrete classes.
The capability to use a subclass object wherever a superclass object is expected without causing issues.
How can you identify potential violations of the Liskov Substitution Principle in your code?
By only using abstract classes and interfaces.
By avoiding inheritance altogether and favoring composition.
By ensuring all methods in subclasses are static.
By looking for instances where a subclass throws an exception not declared in the superclass or introduces behavior that breaks the superclass's contract.
Which of these is NOT a potential consequence of violating the Liskov Substitution Principle?
Increased code complexity and reduced readability.
Improved performance due to optimized subclass implementations.
Higher likelihood of introducing bugs when extending or modifying code.
Decreased code reusability as subclasses may not behave as expected.
What could be a potential downside of excessively applying the Interface Segregation Principle?
It violates the principles of object-oriented programming.
It makes the code more difficult to unit test.
It can lead to a higher number of interfaces, potentially increasing code complexity.
It reduces code reusability.
SOLID principles primarily aim to improve which aspect of software development?
Execution Speed
Algorithm Efficiency
Code Maintainability
Memory Optimization
Which of these is NOT a valid approach to refactor a class violating SRP?
Extract separate functionalities into new classes.
Use design patterns like Strategy or Template Method to separate concerns.
Combine all the responsibilities into a single method for better cohesion.
Delegate responsibilities to other existing classes.
How can you identify multiple responsibilities within a class?
By looking for different reasons to change the class in the future.
By counting the number of lines of code in the class.
By observing how many other classes it interacts with.
By checking if the class name is too long.
Which of these techniques can help achieve the Open/Closed Principle?
Avoiding the use of design patterns.
Copying and pasting code to create new functionality.
Hardcoding values directly into classes.
Using abstract classes and interfaces.
What is a potential drawback of NOT following SRP?
Classes become more focused and have a clearer purpose.
The codebase becomes more difficult to maintain and prone to bugs.
Changes in one part of the code are less likely to affect other parts.
Classes become more reusable and easier to understand.
Which of these is a benefit of adhering to the Single Responsibility Principle?
Increased class size for better code organization.
Tighter coupling between classes for better collaboration.
More complex class design for handling multiple tasks.
Reduced code duplication and improved reusability.
