+# Install Java On Mac With Brew
+
+If you don't already have Java installed on your Mac, you can install it with
+homebrew.
+
+```bash
+$ brew install java
+```
+
+This will take a bit to run and when all is complete, you'll go to run
+something like a version check and see this:
+
+```bash
+$ java -version
+The operation couldn’t be completed. Unable to locate a Java Runtime.
+Please visit http://www.java.com for information on installing Java.
+```
+
+This is because [OpenJDK](https://openjdk.org/) the open-source implementation
+of the Java Development Kit (Java platform) does not get fully set up by
+homebrew.
+
+You'll need to symlink `openjdk` and the exact command with correct paths can
+be found from running the following:
+
+```bash
+$ brew info openjdk
+
+...
+
+For the system Java wrappers to find this JDK, symlink it with
+  sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk
+
+...
+```
+
+The paths may look different for you, so copy the exact command and run that.
+Once the symlink is set, check the version again.
+
+```bash
+$ java -version
+openjdk version "23" 2024-09-17
+OpenJDK Runtime Environment Homebrew (build 23)
+OpenJDK 64-Bit Server VM Homebrew (build 23, mixed mode, sharing)
+```
