JDK 11 is live! Download it from the
Java SE Downloads page. See the JDK 11 Release Notes for detailed information about this release. Highlights include:
- Oracle JDK Migration Guide has been updated for JDK 11 with a description of the major differences between the JDK 10 and JDK 11 releases as well as guidance on how you can migrate from JDK 8 to later JDK releases.
- JDK HTTP Client can be used to request HTTP resources over the network. It supports HTTP/1.1 and HTTP/2, both synchronous and asynchronous programming models, handles request and response bodies as reactive-streams, and follows the familiar builder pattern.
- An implementation of Transport Layer Security (TLS) 1.3 has been included in this release. See Java Secure Socket Extension (JSSE) Reference Guide.
- Local-variable syntax for lambda parameters enables you to declare formal parameters of implicitly typed lambda expressions with the var identifier. See Local-Variable Type Inference.
- You can run a program supplied as a single file of Java source code, including usage from within a script by means of "shebang" files and related techniques. See the java command.
- The Unicode 10.0.0 standard is supported, which includes 16,018 characters and 10 scripts that were introduced since Unicode 8.0.
- The deployment stack, required for Applets and Web Start Applications has been removed. This includes the Java Control Panel used for configuring the deployment technologies, the shared system JRE (but not the server JRE), and the JRE Auto Update mechanism.
