Amazon Corretto 1818.0.2.9

Build and run Java applications on Windows with Amazon Corretto 18, Amazon’s distribution of OpenJDK 18. It provides the Java Development Kit environment used to compile source code, test applications, and execute Java programs. This gives developers and organizations a standard Java foundation for creating software and operating it on Windows systems.

The x64 edition is version 18.0.2.9 and is intended for compatible 64-bit Windows environments. Corretto combines OpenJDK 18 with long-term support, performance enhancements, and security fixes for applications that need ongoing maintenance. It is certified as compatible with the Java SE standard, helping software rely on the APIs and behavior defined by that specification.

Java developers can use it for local development, application testing, and production deployments built around Java. It also suits teams maintaining Java services that need a supported JDK rather than a runtime-only environment. Amazon uses Corretto internally across thousands of production services, providing a concrete example of its use in operational software.
