Java is a multi-platform, object-oriented, and network-centric language that is used for coding everything from mobile apps and enterprise software to big data applications and server-side technologies. In 2023, Java introduced  several exciting features. Java 21 finalizes virtual threads, which make it easier to scale typical thread per request architectures to a theoretically unlimited number of threads.

It is in consideration to enhance the Java programming language with pattern matching for switch expressions and statements. Extending pattern matching to switch allows an expression to be tested against a number of patterns, each with a specific action, so that complex data-oriented queries can be expressed concisely and safely.
