![]() ![]() Lets say we have a factory where cars are manufactured and where cars are also painted. The Open / Closed Principle encourages you to compose simple types into more complex ones using embedding. Let’s take a brief look at the pseudocode implementation of the single responsibility principle. The Single Responsibility Principle encourages you to structure the functions, types, and methods into packages that exhibit natural cohesion the types belong together, the functions serve a single purpose. This principle ensures that a class exists only for a single reason but can have multiple methods to carry out distinct functions.īy following the single responsibility principle, a class should only resolve one aspect of your code. The single responsibility principle states that a class should have only a single reason to change throughout its lifetime. The SOLID principle and its implementation Single responsibility principle It is recommended that your code should rely on abstract classes rather than concrete classes. If we are following the inversion principle, developers should lean towards using interfaces over importing classes because it results in a structured and cleaner code. A concrete class is complete in itself and can extend and can be extended by any class. A brief review on interfaces and concrete classesĪn interface is a blueprint for your class that can be used to implement a class (abstract or not).Ī concrete classes are the final implementation of a blueprint in case you are extending it some abstract super class. The SOLID principle approach ensures that your code is relatively easier to read and understand. Readability is also an essential element in software development because it makes the debugging and refactoring operations easier, especially in open-source projects. ReadabilityĪ well-designed codebase can be easy to understand and read. The SOLID principle incorporates the feature of ensuring that the debugging process of software is much more comfortable. When software applications are not adequately designed, and the codebase is clustered like spaghetti, it is hard to debug applications. Debuggingĭebugging is a crucial part of the software development process. ![]() But the application of SOLID principles makes the extensibility process easier. The procedure of extensibility could be a gruesome process, as you need to build on functionalities that already exist in the codebase, and if the existing functionalities are not adequately designed, this makes it even more difficult to add extra features. If extending the features of an application is not done tactfully, this could affect existing functionalities and cause unintended problems. Software go through phases of upgrades, including extra features. Poorly structured software applications make it difficult to refactor, but it is quite effortless to refactor your codebase with the SOLID principle. Therefore developers need to build applications while keeping in mind the possibility of future changes. The integrity of stable object-oriented applications provides easy access to objects, eliminating the risks of unintended inheritance. The SOLID Principle ensures easy access and control to object entities. The following are the five advantages of the SOLID principle when incorporated in your software design process: Accessibility SOLID principles have been tested and trusted by software developers, and the underlying technique of this principle, when applied correctly, can aid in developing standard object-oriented software applications. In a software development lifecycle, the decision on how accessible and flexible an object is during this object’s design phase will ensure its usability, simplicity, ease of implementation, and accessibility towards making reliable software. How accessible or comfortable would it be to use this cup (object)? But if the handle remains at the side, they remain readily accessible and comfortable to use. Here’s a better analogy imagine if cups had their handles at the top rather than at the side. The object case scenario might confuse newbies in software development. ![]() When creating an object, the object’s design is essential in the software development process, notably in deciding the accessibility scope. The SOLID principle is a design principle and pattern intended to make software designs more understandable, flexible, and maintainable. This principle’s application will be from a universal point of view towards understanding the concept of the SOLID principle, not in relation to any specific programming language. This article explains one of the object-oriented programming design principles that assist you as a software developer in writing clean code. Segregating the responsibilities to individual classes each of which would address a set of related functions should be the primary thought while designing and. There are various software design approaches to ensure an understandable, flexible, and maintainable code base. The only job of this class should be manipulating text.Writing clean code is one of the core precepts of software development. Let’s consider a class that contains code that changes the text in some way.
