Data-Oriented Programming in Java - Records, Sealed Classes, and Pattern Matching

Explore data-oriented programming in Java through a comprehensive 32-minute video presentation by Oracle's Gavin Bierman. Dive into the latest Java features, including records, sealed classes, and pattern matching, and learn how they work together to enable a new programming style well-suited for modern cloud applications. Discover the evolution of Java's Project Amber and its impact on object-oriented programming. Gain insights into new tools like record classes and sealed classes, and understand their practical applications. Examine pattern matching techniques in instanceof and switch statements, and learn how to effectively use these features over sealed hierarchies. Investigate record patterns and their role in consuming and processing data types. Explore JSON value handling and searching techniques within the context of data-oriented programming. By the end of this talk, acquire a solid understanding of how these new Java features can be leveraged to write more efficient and maintainable code for cloud-based applications.
