SOLID Design Principles

Master the SOLID design principles to write clean, scalable, and maintainable code in Java, Python, C++, C#, and JavaScript.

What you'll learn

Single Responsibility Principle (SRP): Design classes that have one, and only one, reason to change, promoting high cohesion and focused functionality.
Liskov Substitution Principle (LSP): Ensure that derived classes can be substituted for their base classes without altering the correctness of the program, maintaining reliable polymorphic behavior.
Dependency Inversion Principle (DIP): Depend on abstractions rather than concrete implementations, fostering a more modular and testable codebase.

Open/Closed Principle (OCP): Develop software entities that are open for extension but closed for modification, allowing for flexible and robust code evolution.
Interface Segregation Principle (ISP): Create client-specific interfaces that are fine-grained and focused, reducing unnecessary dependencies and promoting decoupling.
Practical Application: Engage in hands-on exercises and real-world scenarios to apply SOLID principles effectively in your projects.

Course Overview

In the ever-evolving field of software development, writing code that is both maintainable and scalable is crucial. The "SOLID Design Principles" course at TechGrind is designed to equip developers with a deep understanding of the five foundational principles of object-oriented design: Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion. Through a series of detailed lessons and hands-on examples, you'll learn how to apply these principles to create flexible and robust software systems. By the end of this course, you'll be adept at identifying and implementing SOLID principles in your projects, leading to cleaner code and more efficient development processes.
