Which of these is NOT a valid approach to refactor a class violating SRP?
Combine all the responsibilities into a single method for better cohesion.
Use design patterns like Strategy or Template Method to separate concerns.
Delegate responsibilities to other existing classes.
Extract separate functionalities into new classes.
Why is adhering to the Liskov Substitution Principle important in software development?
It ensures that all methods have the same name across different classes.
It promotes code reusability, maintainability, and reduces the risk of unexpected bugs when modifying code.
It enforces the use of design patterns, making code more readable.
It helps reduce the number of lines of code.
In the context of DIP, what are abstractions typically represented by?
Database connections
Interfaces or abstract classes
Concrete classes
User interface components
What could be a potential downside of excessively applying the Interface Segregation Principle?
It reduces code reusability.
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.
How does using interfaces contribute to the Open/Closed Principle?
Interfaces make code execution slower.
Interfaces define a contract that can be implemented by multiple classes, enabling flexibility.
Interfaces force tight coupling between classes.
Interfaces allow for direct modification of existing class code.
The Liskov Substitution Principle primarily deals with the relationship between:
Classes and their instances
Interfaces and their implementations
All of the above
Subclasses and their superclasses
How does the Open/Closed Principle contribute to creating maintainable code?
It eliminates the need for testing.
It reduces the need for code documentation.
It makes the codebase smaller.
It allows for easier addition of new features without impacting existing ones.
Why is the Open/Closed Principle important in software development?
It complicates the development process.
It promotes code duplication.
It increases the risk of introducing bugs during modification.
It makes code less readable.
What is the core idea behind the Interface Segregation Principle (ISP)?
Subclasses should be substitutable for their base classes.
Clients should not be forced to depend on methods they don't use.
Classes should have only one responsibility.
Code should be open for extension but closed for modification.
How can you identify multiple responsibilities within a class?
By looking for different reasons to change the class in the future.
By checking if the class name is too long.
By observing how many other classes it interacts with.
By counting the number of lines of code in the class.
