How does the single responsibility model work in a Java program? Here we show you what this SOLID principle means, and how to implement the single responsibility model in Java.

Furthermore, the update seeks to rectify the exclusion of primitive type patterns in the pattern matching for instanceof and switch, which had limited Java's expressiveness.

Two OpenJDK draft proposals would enhance the expressiveness of pattern matching in Java and boost data-oriented queries, potentially previewing in Java 17.
