How to Install OpenJDK 11 on Your Mac

Are you looking for an alternative to Oracle Java on your Mac? Look no further than OpenJDK 11, a popular open-source implementation of the Java platform. In this article, we'll guide you through the process of installing OpenJDK 11 on your Mac.

Checking if You Already Have Java Installed

Before we begin, let's check if you already have Java installed on your Mac. To do this, simply type `java -version` in your terminal. If you have Java installed, this command will display the version number of your installed JDK.

Installing OpenJDK 11

If you don't have Java installed or want to install a newer version, we recommend installing OpenJDK 11. To do this, follow these steps:

1. First, download the OpenJDK 11 installation package from the Eclipse Foundation website.

2. Once downloaded, open the package and follow the installation instructions.

Setting Up Your Default JDK

Once installed, you'll want to set up your default JDK. To do this, edit your `~/.zshrc` file by adding the following lines:

```bash

export JAVA_HOME='/usr/libexec/java_home -v 1.8'

export PATH=$JAVA_HOME/bin:$PATH

```

Confirming Your Installation

After setting up your default JDK, you can confirm that OpenJDK 11 is installed by typing `/usr/libexec/java_home -V` in your terminal. This command should display the version number of your installed JDK.

In this article, we've shown you how to install OpenJDK 11 on your Mac and set it up as your default JDK. With this alternative implementation of the Java platform, you'll be able to run Java applications without relying on Oracle's proprietary software.
