Code Refactoring Techniques Quiz

In this code snippet, the method 'printOwing' can be refactored by extracting some of its logic into a separate method for better clarity and maintainability. This technique is known as Extract Method.

Extract Method is the appropriate refactoring technique to improve the code snippet. By extracting the 'moreThanFiveLateDeliveries' method, the code becomes more readable and maintainable by encapsulating a specific behavior within a separate method.

The correct answer is Inline Temp because it involves substituting a local variable reference with the expression it is assigned to.

The correct answer is 'Extract Method'. This refactor technique involves breaking down a large method into smaller ones to improve code readability and maintainability.

Introducing Explaining Variable helps in making the code more readable by breaking down complex calculations into simpler, self-explanatory variables.

The recommended technique for improving the getDistanceTravelled method is Composing Methods, which involves breaking down a complex method into smaller, more manageable methods. This helps improve readability, maintainability, and reusability of code.

The correct answer is 'Composing Methods' as it involves breaking down the large monolithic method into smaller, more manageable methods. This helps with code readability, reusability, and maintainability. 'Unnecessary Code Duplication' is incorrect as it goes against the principle of DRY (Don't Repeat Yourself). 'Variable Declaration' is unrelated to the issue in the code snippet. 'Hardcoding Values' is also not the correct approach to address the problem.

The correct answer is 'Replace Method with Method Object' because this refactoring technique can help transform a complex method into a separate class, making the code easier to understand and maintain.

The correct answer, 'Composing Methods,' emphasizes the practice of breaking down a complex code into smaller and more manageable methods. This makes the code more readable, maintainable, and reusable. The other incorrect answers do not accurately describe the principle demonstrated in the code snippet.

Refactorings are specific techniques used to improve the design of existing code without changing its external behavior. The sections in the refactoring process cover various aspects such as composition of methods, organization of data, simplification of conditional expressions, and more.

The correct name of the refactoring in the image is 'Move Method', which involves moving a method from one class to another. The incorrect answers are other types of refactoring that involve different actions such as extracting a method into its own, inlining a method back into the class, and pushing a method down to subclasses.

Moving Features Between Objects refactoring technique involves moving behavior from one class to another in order to improve the clarity and organization of the code. This can help in distributing responsibility more appropriately across classes. In the provided code snippet, moving the overdraftCharge method to a different class or restructuring the behavior could enhance the overall design.

Refactoring in image refers to the process of restructuring existing computer code without changing its external behavior. This can involve moving features between objects, renaming variables, and other similar operations.

Moving Features Between Objects is a refactoring technique that involves transferring methods or attributes from one object to another to improve the design and maintainability of the code. The other options provided do not specifically relate to the task of moving features between objects.

The correct answer 'Moving Features Between Objects' suggests moving the interest rate field to a higher-level object if many methods are utilizing it, enabling better organization and easier maintenance of the code.

Refactoring of an image in software development refers to restructuring or reorganizing features or components within an object or system. The correct answer, 'Moving Features Between Objects', aligns with this concept by emphasizing the act of transferring characteristics or elements from one object to another. The incorrect answers, including 'Extract Class', 'Merge Objects', and 'Delete Entire Object', do not accurately capture the essence of the refactoring process related to images.

The correct refactoring technique to apply in this scenario is Extract Class. This involves creating a new class to contain some of the features of an existing class, reducing the responsibilities of the original class and improving code organization.

Image refactoring involves restructuring code to improve its readability, maintainability, and efficiency. Moving features between objects is a common refactoring technique that involves transferring responsibilities from one class to another. Inlining a class or method, extracting methods, and renaming variables are also common refactoring strategies, but they do not specifically refer to the process of refactoring an image.

When features become more related to another class, it is often beneficial to inline the class to improve the design and structure of the code, which can be achieved through Inline Class refactoring technique. Code Refactoring is a general term for improving the design and structure of existing code, while Encapsulation involves bundling the data and methods that operate on the data into a single unit. Method Overloading refers to defining multiple methods with the same name but with different parameters.

The correct design pattern for moving features between objects is Hide Delegate, which involves hiding the delegate object and providing methods that delegate directly to it.

The Hide Delegate refactoring technique is used to hide access to another object's methods and fields, providing a clean interface and encapsulation. Encapsulate Field is used to hide direct access to a class field, Move Method is used to move a method to another class, and Replace Data Value with Object is used to convert primitive data values into objects for better manipulation.

The correct process of moving features between objects is known as 'Moving Features Between Objects - Remove Middle Man'.

The correct answer 'Remove Middle Man' suggests that to improve the design, unnecessary middle layer or intermediary objects should be removed to simplify the code structure.

The correct answer refers to the specific process of moving features between objects and introducing local extension, which may involve modifications and extensions to existing objects.

When moving features between objects in object-oriented programming, the recommended approach is to use Moving Features Between Objects technique. This involves transferring behavior and data from one object to another while maintaining encapsulation and functionality.

Organizing data using encapsulation helps in keeping data private and controlled, ensuring better data management and organization.

Moving Features Between Objects involves techniques such as Move Method, Move Field, Extract Class, Inline Class, Hide Delegate, Remove Middle Man, Introduce Foreign Method, and Introduce Local Extension. The incorrect answers, Split Class, Merge Method, and Duplicate Object, are not valid techniques for moving features between objects.

The correct answer provides a list of techniques involved in Composing Methods, including extracting, inlining, replacing, introducing, splitting, removing, and substituting methods or variables. The incorrect answers do not accurately reflect the techniques related to composing methods.

The correct answer, Organizing DataSelf Encapsulate Field, involves encapsulating the class's fields by providing getter and setter methods. This helps in controlling access to the fields and provides an additional layer of protection. The incorrect answers, Extract Method, Inline Method, and Move Method, do not directly address the issue of encapsulation and organizing data within the class.
