Java Programming II: Advanced OOP, Collections, and Concurrency

Ready to take your Java skills beyond basic syntax and build robust, production-ready applications? Moving from writing simple scripts to designing scalable software requires a deep understanding of how Java manages data, files, and concurrent tasks. This text-based course helps you transition from a beginner to a confident intermediate Java developer, learning how to structure complex programs, leverage powerful built-in data structures, and handle asynchronous processes safely. What you'll learn: - Understand intermediate object-oriented principles, including inheritance, polymorphism, and abstract classes. - Master collections and generics to write reusable, type-safe, and highly efficient code. - Implement file I/O operations, object serialization, and database connections to persist application data. - Apply multi-threading and modern concurrency patterns to build responsive, non-blocking applications. - Explore modern Java features such as records, switch expressions, and stream APIs for cleaner code. - Practice designing clean graphical user interfaces and handling events programmatically. The course begins with a solid review of core object-oriented concepts before diving into advanced data structures, concurrency, and database integration. You will read clear explanations, analyze structured code snippets, and complete written exercises designed to reinforce your learning. This course is designed for advancing beginners who already know basic Java syntax and want to level up their software development skills.
