SOLID is an acronym for five important software design principles:
S – Single Responsibility Principle
O – Open/Closed Principle
L – Liskov Substitution Principle
I – Interface Segregation Principle
D – Dependency Inversion Principle
Each principle is important in its own right, but following all five principles will result in more robust, maintainable, and extensible software.
The Single Responsibility Principle states that a class should have a single responsibility, and that responsibility should be entirely encapsulated by the class. This means that the class should have a single purpose, and should not be responsible for anything else.
The Open/Closed Principle states that a class should be open for extension, but closed for modification. This means that new functionality can be added to a class by subclassing it or by implementing new interfaces, but the original code should not be modified.
The Liskov Substitution Principle states that subtypes must be substitutable for their base types. This means that objects of a subclass can be used in place of objects of the base class, and the behavior of the program should not change.
The Interface Segregation Principle states that no client should be forced to depend on methods it does not use. This means that interfaces should be designed so that clients only have to depend on the methods they actually need.
The Dependency Inversion Principle states that dependencies should be inverted. This means that high-
What is the 5 objects oriented design principle from SOLID?
There are five principles of Object Oriented Design, which are commonly referred to as the "SOLID" principles. These principles are:
1. Single Responsibility Principle: A class should have only one responsibility, and that responsibility should be encapsulated within the class.
2. Open/Closed Principle: A class should be open for extension, but closed for modification.
3. Liskov Substitution Principle: Derived classes should be substitutable for their base classes.
4. Interface Segregation Principle: Clients should not be forced to depend on interfaces they do not use.
5. Dependency Inversion Principle: Dependencies should be inverted, so that high-level modules are not dependent on low-level modules.
What is SOLID principle with example?
There are five SOLID principles:
1. Single Responsibility Principle
2. Open-Closed Principle
3. Liskov Substitution Principle
4. Interface Segregation Principle
5. Dependency Inversion Principle
The Single Responsibility Principle states that a class should have one, and only one, reason to change. For example, a class that represents a user interface element like a button should not also be responsible for handling database interactions.
The Open-Closed Principle states that a class should be open for extension but closed for modification. This means that new functionality can be added to a class without having to modify the existing code. For example, a class that represents a shapes could be extended to add a new shape without having to modify the existing code.
The Liskov Substitution Principle states that subclasses should be substitutable for their superclasses. This means that any code that uses a superclass should be able to work with a subclass without any modification. For example, a class that represents a rectangle should be able to work with a class that represents a square, since a square is a type of rectangle.
The Interface Segregation Principle states that clients should not be forced to depend on methods that they do not use. This means that an interface should be split up into smaller interfaces, each of which represents a specific client need. For example, an interface that represents a shape could be split up into separate interfaces for 2D
Can you explain SOLID principles?
There are five SOLID principles which are designed to make software more understandable, flexible, and maintainable.
The Single Responsibility Principle states that a class should have one, and only one, reason to change. This means that a class should have only one responsibility, or only one job to do.
The Open/Closed Principle states that software should be open for extension, but closed for modification. This means that new functionality can be added to a class without changing the existing code.
The Liskov Substitution Principle states that subclasses should be substitutable for their base classes. This means that a subclass should be able to do everything that its base class can do, and more.
The Interface Segregation Principle states that clients should not be forced to depend on methods they do not use. This means that an interface should be split up into smaller interfaces, each of which represents a specific responsibility.
The Dependency Inversion Principle states that dependencies should be inverted. This means that high-level modules should not depend on low-level modules, but rather both should depend on abstractions.
