Harnessing Java 21 for Data Oriented Programming
Harnessing Java 21 for Data Oriented Programming
Discover how the new features in Java 21—records, sealed interfaces, and pattern matching for switch—work synergistically to facilitate data-oriented programming. This video on the 'Tales from the Jar Side' channel demonstrates two practical examples, highlighting the simplicity and benefits of these features. Learn how immutable data models and stateless services can streamline your code and enhance maintainability, especially when dealing with RESTful web services. Delve into enhanced switch expressions and see live coding examples, including testing with JUnit 5. Leave your comments and thoughts on adopting this approach for your Java applications!
