The title of the blog post is IMO a poor choice. The (hidden) subtitle of the post is "Algebraic data types in Java" which is much more descriptive of the content. A better title would have been "Algebraic data types in Java 21".
Perhaps because of the title, many/most of the comments here are off-topic. I was hoping to see more discussion about algebraic data types, strengths and weaknesses of the Java implementation, technical comparisons to other languages, etc.
