Before you dive into Java programming on a Mac, you need to set up your system correctly. To install Java Development Kit (JDK) on Mac, follow these steps:

  1. Visit Oracle’s official website.

  2. Find the latest version of JDK compatible with your version of MacOS.

  3. Download the .dmg file.

  4. Follow the instructions provided in the installation assistant.

With installed JDK, you’ve successfully prepared your Mac for Java development.

Section 3: Configuring a Java IDE on Mac

Integrated Development Environments (IDEs) enhance Java programming on Mac significantly. Whether you’re using IntelliJ IDEA, Eclipse, or NetBeans, the right IDE ensures seamless Java development on MacOS. Here’s how to install IntelliJ IDEA:

  1. Download the installer package from the official IntelliJ IDEA website.

  2. Open the .dmg package.

  3. Move IntelliJ IDEA to the Applications folder.

And voila, you now have IntelliJ IDEA on your Mac.

Section 4: Coding in Java on a Mac

Now that your Mac is prepped and ready, it’s time to dive into Java. A simple "Hello, World" program in Java looks like this:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");

To run this program, save it as, navigate to the directory where you saved the file in terminal, and type:

java HelloWorld

The console will display "Hello, World!".
