'Java developers want continued innovation with modern programming language features, developer experience enhancements, cloud managed services, and stability,' said James Governor, Principal Analyst, RedMonk. 'We continue to make technical investments that improve the performance, stability, and security of the Java SE Platform implementations, as well as the Java Development Kit.' 'The release of Java 18 demonstrates Oracle's continued commitment to provide enterprises and developers faster access to enhancements with the six-month feature release cadence,' said Georges Saab, Vice President of Development, Java Platform Group, Oracle. Developers can explore two incubating modules: the Vector API (JEP 417) and the Foreign Function and Memory API (JEP 419), as well as a preview feature: Pattern Matching for Switch (JEP 420).

These include the capability to add Code Snippets in Java API Documentation (JEP 413), which simplifies the addition of sample source code in API documentation, and Simple Web Server (JEP 408) for prototyping and testing. The latest Java Development Kit (JDK) provides updates and improvements with nine JDK Enhancement Proposals (JEPs). Java 18 (Oracle JDK 18) delivers thousands of performance, stability, and security improvements, including nine enhancements to the platform that will further improve developer productivity. Oracle today announced the availability of Java 18, the latest version of the world's number one programming language and development platform. Installation instructions are located on the Java SE documentation site. Some compatibility-breaking changes were required to close potential security holes or to fix implementation or design bugs. Most failures to do so are considered bugs, except for a small number of cases where compatibility was deliberately broken, as described on our compatibility web page.

Although some incompatible changes were necessary, most software should migrate to the current version with no changes. Every effort has been made to support programs written for previous versions of the Java platform. See the JDK 18 Migration Guide for a list of known compatibility issues.
