The descriptions also identify potential compatibility issues that you might encounter when migrating to JDK 16. This document includes descriptions of those new features and enhancements that are also changes to the specification. Another source of information about important enhancements and new features in Java SE 16 and JDK 16 is the Java SE 16 (âJSR 391) Platform Specification, which documents the changes to the specification made between Java SE 15 and Java SE 16.

It includes a complete implementation of the Java SE 16 Platform and additional Java APIs to support developing, debugging, and monitoring Java applications. The APIs described here are those that are provided with the Oracle JDK. In some cases, the descriptions provide links to additional detailed information about an issue or a change. This section describes some of the enhancements in Java SE 16 and JDK 16. The version number is 16.0.2.Ĭomplete release notes for Java SE JDK 16.0.2 can be found here. The full version string for this update release is 16.0.2+7 (where "+" means "build"). Why would you need the JDK then? Because the application server will convert JSP into Java servlets and needs to use the JDK to compile the servlets. For example, if you are deploying a web application with JSP, you are technically just running Java programs inside the application server. Sometimes, even if you are not planning to do any Java development on a computer, you still need the JDK installed. The new license permits certain uses, such as personal use and development use, at no cost – but other uses authorized under prior Oracle JDK licenses may no longer be available. The new Oracle Technology Network License Agreement for Oracle Java SE is substantially different from prior Oracle JDK licenses.

You can download the version you need below: Java 8, Java 11 and Java 17 are the three long-term support versions recommended by Oracle. However, many versions of Java are actively maintained for compatibility purposes.

The latest version of Java is Java 20 or JDK 20 released on March, 2023. It is capable of creating and compiling programs. It has everything the JRE has, but also the compiler (javac) and tools (like javadoc and jdb). The JDK is the Java Development Kit, the full-featured SDK for Java.
