Shulou(Shulou.com)11/24 Report--

Thank CTOnews.com netizens Shuiyou 233and T-type human for the clue delivery! CTOnews.com, September 20, yesterday night, Oracle announced the official version of Java 21 and the corresponding JDK 21 development kit, which is the latest long-term support (LTS) version after JDK 17 and will be supported for at least 8 years.

The company also announced that long-term support for Java 11, which was released five years ago, has been extended to January 2032.

Java 21 boasts thousands of performance, stability and security improvements. The new JDK 21 includes a pre-emptive experience of 15 improvements announced at the Oracle CloudWorld 2023 conference, including support for virtual threads to improve overall throughput and increased support for vector application programming interfaces (API) to make it easier to build Java applications involving artificial intelligence AI models.

Java 21 also introduces a new Generational ZGC garbage collection mechanism and discards the 32-bit x86 interface that is ready to be deleted.

In addition, CTOnews.com found that in order to lower the learning threshold of Java and facilitate educators to gradually introduce programming concepts, Java 21 also supports undeclared classes, variables, instance master methods, and so on, which is tantamount to abandoning some strongly typed designs.

Georges Saab, Senior Vice President and Chairman of OpenJDK, Oracle Java platform, said: "Java remains the language and platform of choice for developing robust, scalable and secure applications for organizations and millions of people around the world. New enhancements in Java 21 enable developers to build better applications faster than ever before. In addition, business support will be available for at least eight years, enabling customers to migrate at their own pace."
