Quick and Easy Steps to Check Your Java Version on macOS

 If you’re a developer or just someone who occasionally works with Java on macOS, it's essential to know which version of Java you have installed. Knowing your Java version is especially important when you’re trying to troubleshoot compatibility issues or when you're preparing to upgrade or install a newer version of Java. Whether you're using macOS for development, running applications that depend on Java, or just curious about what version you're working with, checking your Java version on macOS is a quick and easy task.

In this guide, we’ll walk you through the simplest ways to check your Java version on macOS, without diving into complicated terminal commands or unnecessary steps. So let’s get started with the most effective ways to perform a Java Version Check on macOS.

1. Using the Terminal

The most straightforward method to check your Java version on macOS is by using the built-in Terminal app. The Terminal allows you to interact with your Mac via text-based commands, and checking your Java version is no exception.

Here’s how you do it:

  1. Open the Terminal: You can find Terminal by navigating to your Applications folder, then into Utilities, where you’ll find the Terminal app. Alternatively, you can use Spotlight by pressing Command + Spacebar, typing "Terminal," and hitting Enter.
  2. Type the Command: In the Terminal window, type the following command:

3.  java -version

  1. Press Enter: After typing the command, press the Enter key. The Terminal will process your request and display the Java version installed on your macOS system.
  2. Review the Output: You’ll see something similar to the following:

6.  java version "1.8.0_291"

7.  Java(TM) SE Runtime Environment (build 1.8.0_291-b10)

8.  Java HotSpot(TM) 64-Bit Server VM (build 25.291-b10, mixed mode)

This indicates that you have Java 1.8.0_291 installed on your macOS.

2. Using System Preferences (For Java 8 and Later)

If you're running Java 8 or later, macOS also includes a graphical way to check your Java version using the System Preferences app. This method can be handy for those who prefer not to use the Terminal.

Here’s how to do it:

  1. Open System Preferences: Click on the Apple logo in the top-left corner of your screen, and from the drop-down menu, select System Preferences.
  2. Java Control Panel: In the System Preferences window, look for an icon labeled Java. If it’s not visible, it may be because Java isn’t installed, or you may need to install the Java Control Panel. If you do see it, click on it to open the Java Control Panel.
  3. Check the Version: Once the Java Control Panel opens, click on the About tab. A small window will appear, showing the current Java version installed on your macOS system.

This method is very useful for a quick check, but keep in mind that it only works with versions 8 and higher.

3. Check via Java Preferences (For Older Versions)

For those using older versions of Java, macOS previously had a dedicated Java Preferences app. If you're running macOS High Sierra or earlier, you might still be able to access it. However, this app was deprecated in newer versions of macOS, so it’s only applicable if you're using an older macOS.

Here’s how to check the Java version via Java Preferences:

  1. Open Java Preferences: Navigate to the Applications folder, then go to Utilities, where you should find the Java Preferences app (if you’re using an older macOS).
  2. Check the Version: Once the Java Preferences window is open, you’ll see a list of installed versions of Java. The version that’s listed at the top is the one currently active on your macOS.

However, because this method is outdated and not available in more recent macOS versions, it’s better to use the Terminal method for an up-to-date Java Version Check on macOS.

4. Java Version with Homebrew (If Installed via Homebrew)

If you’ve installed Java using Homebrew, the popular package manager for macOS, you can also use it to check the version. This method is helpful for users who prefer Homebrew for managing software on their systems.

Here’s how you can check the Java version through Homebrew:

  1. Open Terminal: As before, open the Terminal application.
  2. Run the Homebrew Command: Type the following command to check which version of Java is installed via Homebrew:

3.  brew cask info java

  1. Check the Output: This command will show the current version of Java installed through Homebrew, along with other related details. It’s a quick way to verify what version you’re using if Java was installed via Homebrew.

5. What to Do After Checking the Java Version

Once you’ve checked your Java version on macOS, you might want to take action depending on the result:

  • If your version is outdated: You can easily download and install a newer version of Java from Oracle’s official website or via Homebrew for the latest Java release.
  • If there are compatibility issues: You might need to update specific libraries or applications depending on the Java version they require.

It's always a good practice to keep your Java up to date, especially for security and performance improvements.

Conclusion

Checking your Java version on macOS is a simple task that you can accomplish in just a few easy steps. Whether you're using the Terminal, System Preferences, or Homebrew, you can quickly find out which version of Java you’re working with. This knowledge is essential for troubleshooting, ensuring compatibility, and maintaining the smooth running of Java-based applications. Now that you know how to perform a Java Version Check on macOS, you can stay ahead of any issues and keep your system up to date.
