Java Back-End Development: Build Web Applications and APIs

Starting your journey in back-end development can feel overwhelming with so many frameworks, databases, and tools to master. This text-based course guides you step-by-step through the core concepts of Java back-end programming, turning complex code into clear, manageable concepts. You will transition from writing basic Java programs to designing, building, and deploying fully functional web applications and RESTful APIs. By understanding how servers, databases, and clients communicate, you will gain the foundational skills needed to build robust back-end systems. What you'll learn: Understand core back-end architecture, HTTP protocols, and how web servers handle requests; Write clean Java code using modern features like records and type inference; Build robust RESTful APIs to handle JSON data and communicate with clients; Integrate relational databases to store, retrieve, and manage application data securely; Apply modern testing practices using JUnit to ensure your back-end code runs reliably; Configure container basics to package and prepare your applications for deployment. We begin with foundational definitions and key back-end terminology before moving into database integration, API design, and modern deployment practices. Through structured written explanations and clear code examples, you will build a solid programming foundation. This course is designed specifically for beginners with no prior back-end experience; a basic familiarity with general programming concepts is helpful but not required.
