Comprehensive coverage of Java 8 to Java 21 features, including lambdas, streams, records, pattern matching, and sealed classes
Hands-on coding labs demonstrating functional programming, parallel streams, and the Java Platform Module System (JPMS)
Real-world applications, such as CheckoutService and HTTP client, bridging modern Java concepts to production-ready development
This course is designed for Java developers, software engineers, and backend developers seeking to upgrade their Java knowledge to the latest standards. Participants should have basic proficiency in Java programming, including object-oriented concepts. Prior experience with Java 7 or earlier is beneficial but not required, as the course revisits fundamental concepts before diving into modern enhancements.
This course guides developers through Java’s evolution from version 8 to 21, focusing on modern features that enhance code readability, performance, and efficiency. It starts with Java 8 fundamentals like lambdas, functional interfaces, and the Streams API, enabling a shift from imperative to declarative programming. Learners will set up their development environment and understand why Java 8 was a transformative release. As the course progresses, participants explore features from Java 9 to 21, including the Java Platform Module System (JPMS), local variable type inference (var), text blocks, enhanced switch expressions, records, sealed classes, and pattern matching. Object-oriented programming improvements and functional programming techniques are emphasized to help developers write concise, type-safe code. Practical modules cover parallel streams, the modern HTTP client, and date/time APIs for robust scheduling. The course culminates in a real-world CheckoutService application using sealed classes, a simple web server, and modern Java tooling. By the end, developers will have an up-to-date skill set to confidently build scalable, enterprise-grade Java applications.
