How to Set or Change the Default Java (JDK) Version on macOS? 😎✨🔧

Are you tired of dealing with outdated Java versions on your macOS? Don't worry, we've got you covered! In this guide, we'll walk you through the process of setting or changing the default Java Development Kit (JDK) version on your Mac. 🚀🍎

The Problem 🤔❓

So, you're facing the challenge of needing to use a specific version of Java, but your macOS seems to have a different default version set up. It can be frustrating, especially when certain applications or software require a specific JDK version to work correctly. 🤯

The Solution 💡✅

Step 1: Determine Installed JDKs 📝🔍

The first step is to identify the JDK versions installed on your macOS. Open Terminal, and type the following command:

/usr/libexec/java_home -V

This command will display a list of installed JDK versions along with their paths. Make a note of the version you wish to set as the default. 📝

Step 2: Set the Default JDK 🔧🔨

Now that you know which JDK version you want as the default, you can set it using the export command in Terminal. Replace path_to_JDK with the path of the desired JDK version from the previous step.

export JAVA_HOME=/path_to_JDK

To verify that the default version has been successfully changed, you can type the following command:

java -version

This will display the version of Java currently set as the default. 🎉

Step 3: Permanently Set the Default JDK 🔄🔐

To ensure that your Mac remembers the new default JDK version even after restarts or updates, you can add the export command to your .bash_profile or .zshrc file. 🔒

• For Bash users:

echo 'export JAVA_HOME=/path_to_JDK' >> ~/.bash_profile
source ~/.bash_profile

• For Zsh users:

echo 'export JAVA_HOME=/path_to_JDK' >> ~/.zshrc
source ~/.zshrc

Setting or changing the default Java (JDK) version on macOS might seem like a daunting task, but with these simple steps, you'll be able to conquer it like a pro! Remember to choose the JDK version you need and update your shell profile to make the changes permanent. 🙌
