About this lesson

Want to understand SOLID principles without complex code? In this video, I explain all 5 SOLID principles using simple real-life examples so beginners can understand software design easily. SOLID principles help you write clean, maintainable, scalable, and flexible code. If you are learning object-oriented programming, system design, or preparing for software engineering interviews, this video will give you a strong foundation. In this video, we cover: ✅ Single Responsibility Principle (SRP) ✅ Open Closed Principle (OCP) ✅ Liskov Substitution Principle (LSP) ✅ Interface Segregation Principle (ISP) ✅ Dependency Inversion Principle (DIP) Real-life examples included: • Chef example for SRP • Mobile charger example for OCP • Car replacement example for LSP • TV remote example for ISP • Electric socket and adapter example for DIP This is the first video in the SOLID principles series. In upcoming videos, we will go deeper into each principle with practical coding examples. If you are a beginner in software development, Java, Python, system design, or object-oriented programming, this series will help you build better software.
