QUESTION 2
Which of the following is true about the Extract function refactoring technqiue
The technique might require introducing state variables to the class
The extracted function will have no parameters
When applied, local variables from the original (refactored function) that are used in the extracted code are passed as parameters to the extracted function
QUESTION 3
Which of the following is true about Introduce parameter object refactoring technique?
Does not work with Java
The technique is used to increase performance as it requires less memory
You will need to create a new structure (class) for the grouped data if that structure does not already exist Used to to shorten methods
QUESTION 4
Which of the following design patterns can be descirbed as a refactoring for having complex switch statements?
Factory method
Singleton
Decorator
Abstract Factory
The Extract function refactoring technique involves taking a portion of code from an existing function and moving it into a new, separate function. The technique may or may not require introducing state variables to the class, depending on the specific situation. It is also possible for the extracted function to have parameters if necessary, but it is not true that the extracted function will have no parameters by default.
When the technique is applied, local variables from the original (refactored) function that are used in the extracted code are typically passed as parameters to the new function. This ensures that the extracted function has access to the necessary information to perform its task, without relying on any external variables or dependencies.
