How to Set Up Java in Visual Studio Code on MacOS

Visual Studio Code is a widely-used code editor that supports several programming languages including Java.

Setting up Java in Visual Studio Code on MacOS can be done in a few simple steps. In this article, we’ll guide you through the process of installing Java and configuring Visual Studio Code to use it.

Step 1: Install Java Development Kit (JDK)

The first step to setting up Java in Visual Studio Code on MacOS is to install the Java Development Kit (JDK). The JDK is a software development environment used to develop Java applications. Follow the steps below to install JDK on MacOS:

1. Visit the Oracle website and download the latest version of the JDK for MacOS. You may need to create an Oracle account if you don’t already have one.
2. Once the download is complete, double-click the .dmg file to open the installer.
3. Follow the prompts in the installer to complete the installation process.
4. After the installation is complete, verify that the JDK is installed correctly by opening the Terminal app and running the command:

java -version

If the command returns the version of the JDK, it means the installation was successful.

Step 2: Install Visual Studio Code

If you haven’t installed Visual Studio Code on your MacOS yet, you can download it from the official Visual Studio Code website. Once the download is complete, double-click the .dmg file to open the installer, and follow the prompts to complete the installation process.

Step 3: Install the Java Extension Pack

After installing Visual Studio Code, you need to install the Java Extension Pack. The extension pack includes a set of tools and utilities for Java development. To install the extension pack, follow the steps below:

1. Open Visual Studio Code.
2. Click on the Extensions icon in the left-hand menu bar.
3. Search for “Java Extension Pack” in the search bar.
4. Click on the Install button to install the extension pack.
5. Once the installation is complete, restart Visual Studio Code to activate the extension.

Step 4: Configure Visual Studio Code for Java Development

After installing the Java Extension Pack, you need to configure Visual Studio Code to use the JDK you installed in step 1. To do this, follow the steps below:

1. Open Visual Studio Code.
2. Click on the Preferences icon in the left-hand menu bar.
3. Click on Settings to open the settings editor.
4. Search for “Java Home”.
5. Set the Java Home path to the location where you installed the JDK. For example, if you installed the JDK in the default location, the Java Home path should be:

/Library/Java/JavaVirtualMachines/jdk-VERSION.jdk/Contents/Home

Replace “VERSION” with the version number of the JDK you installed.

6. Save the changes and close the settings editor.

Step 5: Create a Java Project in Visual Studio Code

After configuring Visual Studio Code for Java development, you can create a Java project and start coding. To create a Java project, follow the steps below:

1. Open Visual Studio Code.
2. Click on the Explorer icon in the left-hand menu bar.
3. Click on the New Folder icon to create a new folder for your project.
4. Open the folder by clicking on it in the Explorer.
5. Click on the New File icon to create a new Java file.
6. Name the file with the “.java” extension. For example, “HelloWorld.java”.
7. Start coding your Java project.
