[100% Off] Low Level Design: Opp, Solid Principles And Design Patterns
Master Java OOP, SOLID Principles, Design Patterns, UML Diagrams, and build a Taxi Booking System from scratch.
What you’ll learn
- Understand and apply core OOP concepts, including encapsulation, abstraction, inheritance, and polymorphism.
- Write clean, maintainable, flexible, and extensible Java code using the five SOLID principles.
- Understand and implement Factory, Strategy, Observer, and Singleton patterns to solve common software design problems.
- Identify entities, attributes, and relationships to break down real-world problems into software components.
- Visualize classes, attributes, methods, and relationships using UML class diagrams before implementation.
- Apply OOP, SOLID principles, and design patterns to design and implement a practical Taxi Booking System.
Requirements
- Basic knowledge of Java programming, including variables, data types, loops, conditional statements, and methods, is recommended.
- A general understanding of programming fundamentals will be helpful.
- Learners should have a computer with Java JDK installed and an IDE such as IntelliJ IDEA, Eclipse, or VS Code.
- No prior knowledge of Low-Level Design (LLD), SOLID principles, design patterns, or UML diagrams is required, as all concepts are explained step by step.
Description
Learn Low-Level Design (LLD) with Java – From Fundamentals to Implementation
Want to write clean, maintainable, and well-structured Java applications?
Understanding Java syntax is just the beginning. As a software developer, you also need to understand how to design software components, organize classes, define relationships, and build applications that are easy to maintain and extend.
In this beginner-friendly course, you will learn the fundamentals of Low-Level Design (LLD) using Java. We will start with essential Object-Oriented Programming concepts, gradually explore SOLID principles and commonly used design patterns, and finally apply everything in a practical Taxi Booking System project.
The course focuses on explaining concepts clearly with practical examples so you understand not only how to implement them, but also why they are important in real-world software development.
What You Will Learn
Object-Oriented Programming: Understand interfaces, abstract classes, encapsulation, data hiding, and polymorphism.
SOLID Principles: Learn and apply all five SOLID principles to create clean and maintainable code.
Design Patterns: Understand and implement Factory, Strategy, Observer, and Singleton patterns.
System Modeling: Identify entities, attributes, and relationships when analyzing real-world problems.
UML Class Diagrams: Learn to visualize classes, attributes, methods, and relationships before implementation.
Practical Project: Design and implement a Taxi Booking System using Java.
