6 Installed Directory Structure of JDK

The modular runtime image of JDK 22 contains the following folders:

Note:

In macOS, the JDK installation path is/Library/Java/JavaVirtualMachines/jdk-interim.update.patch.jdk/Contents/Home.

/jdk-interim.update.patch.jdk

The root directory of the JDK software installation. This directory also contains Copyright, README, and Release files.

/jdk-interim.update.patch.jdk/Contents/Home/

The root directory of the JDK software installation on macOS.

/jdk-interim.update.patch.jdk/bin

The executable and command-line launchers that are defined by the modules linked to the image.

/jdk-interim.update.patch.jdk/conf

The .properties, .policy, and other configuration files intended to be edited by developers, deployers, and end users.

/jdk-interim.update.patch.jdk/lib

The private implementation details of the runtime system. These files are not intended for external use and must not be modified.

The lib directory on macOS or the lib/$ARCH directory on Linux contains the runtime system's dynamically linked native libraries.

/jdk-interim.update.patch.jdk/jmods

The compiled module definitions.

/jdk-interim.update.patch.jdk/legal

The copyright and license files for each module.

/jdk-interim.update.patch.jdk/lib/src.zip

The archive that contains the source code for the Java platform.

/jdk-interim.update.patch.jdk/include

The C-language header files that support native-code programming with the Java Native Interface and the Java Virtual Machine (JVM) Debugger Interface.

Note:

Installing a JDK update release will replace the existing version of the same feature release. For example, when you install JDK 22.0.1 after installing JDK 22, the installer uninstalls JDK 22 and installs JDK 22.0.1. However, you can install JDK 22 and JDK 11 simultaneously. In the JDK installation location, jdk-22 and jdk-11 directories get created.
