What is Java Preview?

Java Preview is a preview version of the Java Development Kit (JDK) that includes experimental features not yet available in the production version. These features are proposed additions that have not been finalized or incorporated into the core Java platform. However, they offer developers a glimpse into the future direction of Java and provide an opportunity to provide feedback on their functionality and usability.

Key Features of Java Preview

• Access to Experimental Features: Java Preview provides developers with access to cutting-edge Java features under development, allowing them to explore and experiment with upcoming innovations.
• Early Feedback Mechanism: Java Preview serves as a feedback mechanism for Oracle, enabling developers to provide input on the design and implementation of new features. Feedback helps shape the future of Java and guide its development roadmap.
• Compatibility with Production Code: Java Preview features can be used alongside production code, facilitating the integration of experimental features into existing projects.
• Separate Installation: Java Preview does not overwrite the production JDK installation, ensuring a stable development environment.
