CH-2 AGILE I am preparing for my college exam for a subject called 'Agile Development and UI UX' and for that I need you to provide the answer of the questions which I will ask to you. This will help me to prepare. Now I will ask you the questions of a chapter called 'Agile Design'. Got it! Feel free to ask your questions about "Agile Design," and I'll do my best to help you prepare. 2/2 Explain SRP: Single Responsibility Principle with suitable example. keep the explanation easy to understand. do not include the code examples and keep the answer precise The Single Responsibility Principle (SRP) is one of the key principles of software design in the SOLID principles. It states that a class or module should have only one reason to change, meaning it should only have one responsibility or job. Explanation: Single Responsibility: Each class or module should focus on a single task or responsibility. This makes the system easier to understand, maintain, and test. Benefits: Easier to manage: Changes in one part of the system have minimal impact on other parts. Better readability: When a class has a clear purpose, it’s easier for developers to understand its functionality. Simplified testing: Focusing on one responsibility allows for more straightforward unit tests. Example: Imagine a class called Report that handles both generating reports and sending them via email. 1/20
Violation of SRP: If you need to change how reports are generated, you also have to consider how that affects the email-sending functionality. This makes the class complex and harder to manage. Adhering to SRP: Instead, you could have two classes: ReportGenerator (responsible for creating reports) and EmailSender (responsible for sending reports via email). Each class has its own distinct responsibility, making the system cleaner and easier to maintain. By applying SRP, you ensure that your code remains organized and adaptable to change! now give a very easy to understand code example Sure! Here's a simple code example to illustrate the Single Responsibility Principle (SRP). Example: Violating SRP Issue: The Report class has two responsibilities: generating the report and sending it via email. If the email sending logic changes, you'll have to modify this class, which makes it harder to maintain. Adhering to SRP python class Report: def generate_report(self): # Logic to generate the report return "Report Content" def send_report(self, email_address): # Logic to send the report via email print(f"Sending report to {email_address}") # Usage report = Report() content = report.generate_report() report.send_report("
[email protected]") 2/20
