Description
This course delivers an in-depth, implementation-focused exploration of Java 25 latest features, specifically designed for experienced Java and backend developers.Java 25 introduces significant advancements in performance optimization, concurrency, and developer productivity. In this course, you will gain hands-on experience with Virtual Threads, Scoped Values, Structured Concurrency, and enhanced core APIs, demonstrated through production-grade use cases commonly found in enterprise systems.Unlike general Java tutorials, this course focuses exclusively on Java 25 new features and their practical adoption in real-world applications. Each topic moves beyond theory and into code-level implementation, highlighting design considerations, performance implications, and best practices for modern Java development.You will also learn how and when to adopt these features in existing Spring Boot, Microservices, and backend architectures, including migration strategies and common pitfalls to avoid in production environments.Each tutorial is structured with a clear learning flow: the core concept is introduced first, followed by the real-world problem it solves, a practical implementation, an explanation of internal JVM behavior, and assignments to reinforce hands-on understanding.By the end of this course, you will have a clear, expert-level understanding of Java 25, enabling you to confidently modernize applications, improve system scalability, and write efficient, future-ready Java code.[ Some graphics in this course are used under Freepik license: Designed by Freepik ]
