The course provides a complete pathway to master Java’s data structures and backend development with Spring Boot, equipping learners with skills to build efficient and scalable applications. It is designed for learners with prior Java knowledge who want to strengthen their problem-solving abilities while gaining hands-on backend expertise.

You will begin with Java data structures, learning to work with arrays, strings, and multidimensional data, while exploring advanced manipulation through StringBuilder, StringBuffer, and the Collections Framework. Practical exercises will help you implement stacks, queues, and hashing for real-world problem-solving. The course then transitions into backend development with Spring and Spring Boot, where you’ll understand dependency injection, MVC design, and application layering. You will gain confidence in creating modular applications that are easy to maintain and extend. Finally, you’ll dive into RESTful services, building secure APIs using Spring Boot, performing CRUD operations, handling JSON communication, and applying Spring Security for authentication and authorization. This structured journey ensures you can connect computer science fundamentals with backend development practices used in industry. By the end of this course, you will be able to: - Implement core Java data structures, including stacks, queues, and hashing. - Apply StringBuilder, StringBuffer, and the Collections Framework for efficient data management. - Build modular backend applications using Spring and Spring Boot. - Create and secure RESTful APIs with CRUD operations and Spring Security.
