Java 23 significantly enhances developer productivity and performance through features like primitive type patterns in switch statements, Markdown comments, a new class-file API, and improved stream handling.
The introduction of Markdown Documentation Comments allows developers to enhance JavaDoc comments with formatting options, leading to more readable and easier-to-write documentation, thereby improving the overall developer experience.
The new Vector API empowers developers to perform efficient data processing through vector computations that can be compiled correctly at runtime across various CPU architectures.
Java 23 also includes the deprecation of certain memory-access methods in sun.misc.Unsafe, prompting developers to adopt safer alternatives like the VarHandle API for better memory management.
