Dependency Inversion Principle Tutorial with Java Code Example for Beginners

Dependency Inversion Principle is the fifth and final Solid principle. Robert C. Martin’s definition of the Dependency Inversion Principle consists of two parts. a. High-level modules should not depend on low-level modules. Both should depend on abstractions. b. Abstractions should not depend on details. Details should depend on abstractions. An important detail to note here is that high-level and low-level modules depend on the abstraction. It splits the dependency between the high-level and low-level modules by introducing an abstraction between them. Dependency inversion principle is related to other SOLID principles. That is, if you consequently apply the Open/Closed Principle and Liskov Substitution Principle in your code, it will automatically compliance with Dependency Inversion Principle. Dependency Inversion principle introduces an interface abstraction between higher-level and lower-level software components to remove the dependencies between them. This aims to reduce the coupling between the classes by introducing abstraction between the layer. ** Use of Dependency Inversion Principle ** 1. Use Dependency Inversion principle if you want high level class should not depends on low level classes. 2. Use Dependency Inversion if you want high level and low-level classes depends on abstractions. 3. Use Dependency Inversion if you Abstraction (interface or abstract class) should not depend on detail but detail (implementation class) should depend on abstraction 4. Use Dependency Inversion when you don’t want to achieve loose coupling between classes. ** Benefits of Dependency Inversion Principle ** 1. Dependency Inversion principle ensures loose coupling between classes. 2. Dependency Inversion Principle make sure high-level class not dependent on low level classes. 3. Dependency Inversion principle makes sure abstraction should not depend on detail but details should depend on abstraction. ** Topics Covered ** 1. Introduction of Dependency Inversion Principle 2. Real world example of Dependency Inversion Principle 3. Java code implementation of Dependency Inversion Principle 4. Usage of Dependency Inversion Principle 5. Advantage of Dependency Inversion Principle 6.
