What does the single responsibility principle entail Mcq?
The single-responsibility principle is a computer-programming principle that states that every module or class should have responsibility over a single part of the functionality provided by the software, and that responsibility should be entirely encapsulated by the class, module or function.
Which of the following statements describe the single responsibility principle?
The correct answers are: Objects should have a singular purpose. Generally, a class wouldn’t make calls to external methods. A class should only have one reason to change.
Who is the author of the single responsibility principle?
Single Responsibility Principle (SRP), as defined by Robert C. Martin states: This is very different from the “a class should do only one thing” version. In one of his later books (“Clean Architecture”, reviewed here) Robert C. Martin goes even further, clarifying his intent behind this principle: This is even more precise.
How to use the single responsibility principle in coding?
Use common sense when developing code. There is no point in having multiple classes that just contain one function. Maximize the features of the single responsibility principle using Stackify’s free code profiler, Prefix, to write better code on your workstation.
Do you oversimplify the single responsibility principle?
However, make sure to not oversimplify your code. Some developers take the single responsibility principle to the extreme by creating classes with just one function. Later, when they want to write some actual code, they have to inject many dependencies which makes the code very unreadable and confusing.
Why is it important to keep class focused on a single concern?
The reason it is important to keep a class focused on a single concern is that it makes the class more robust. Continuing with the foregoing example, if there is a change to the report compilation process, there is a greater danger that the printing code will break if it is part of the same class.
