The first thing you need to do is download Java SE (Standard Edition) from Oracle. You may have Java installed in some form on your Mac already (probably the consumer version), but Java SE for. Setting Up for Development Getting Xcode. Apple now provide the Xcode suite as a free download from the App Store. Setting Up Homebrew. Homebrew provides a package management system for macOS, enabling you to quickly install and update. Installing the Git Version Control System. Select the zone on which you want to change the Java security settings. In the Security level for this zone frame, click Custom Level. In Internet Explorer, click Custom Level, and then click Settings. View the Microsoft VM section (the Java section in Internet Explorer) In the list of Java Permissions under the Microsoft VM, click Custom.

Update: Please see our Java Support in Safari 12 article for the latest information on Java support in Safari on macOS. The option to allow plug-ins described below is no longer supported by Safari.

Java Settings For All Users

Trying to run a Java application on your Mac and need to set your JAVAHOME? Follow the instructions below to quickly and easily do it: Open Terminal Confirm you have JDK by typing “which java”. It should show something like /usr/bin/java. Check you have the needed version of Java, by typing “java -version”. Apple's Mac OS X is the second most widely used operating system after Windows and no surprise that many Java programmer use Macbook Pro for Java development. Mac's UNIX-like feature is added advantage because most of the real world Java servers runs on.

No matter which web browser you use on your computer, you will need the Java plug-in from Oracle in order to view content that uses Java, such as Java applets. The Safari web browser on Mac from Apple is no exception. Java applets are common on the Internet. It is important, therefore, to know how to enable and disable Java in Safari on Mac if it is your web browser of choice.

First, please be certain the version of Java on your computer is current. Once you have verified Java is installed on your computer, please follow the instructions below to learn how to enable or disable Java in Safari on Mac.

1. Launch the Safari application, and click the Safari file menu. Select Preferences from the drop-down menu.

2. The Preferences dialog will launch in a new window. Click the Security icon.

To enable Internet plug-ins, including Java, to load in Safari, check the Internet Plugins: Allow Plug-ins check box. Unlike Safari on Windows, there is no individual check box for Enable Java for Safari on Mac.

3. When you encounter Java content in Safari, Safari will block the content from loading. You will see a notification in the browser window where the Java content would otherwise load:

4. Click the right-arrow in the notification. A Do you want to trust the website… dialog will display.

In this case, we visited the Java.com web site to load a test Java applet. Since we trust the web site, we clicked the Trust button to allow java.com to use the Java plug-in. When we re-visit the Java content on this web site, the Java content will now display.

5. You can manage your trusted web sites, and choose degrees of trust, by returning to the Security settings of Safari’s Preferences window. Adjacent to the Internet Plugins: Allow Plug-ins check box, click the Website Settings… button.

A new dialog will launch. The dialog displays all of the Internet plug-ins currently installed. To manage the web sites you have trusted to use the Java plug-in, click Java in the left navigation pane. The list of web sites you have already trusted will display.

Use the pull-down menu adjacent to the web site in the list to choose a level of trust you want to extend to this site. You may choose from Ask, Block, Allow or Allow Always (or Run In Unsafe Mode). You may delete a web site from this list by highlighting it with your mouse, and clicking the minus button at the bottom of the list.

Setting up VS Code for Java development

Coding Pack for Java

To help you set up quickly, you can install the Coding Pack for Java, which includes VS Code, the Java Development Kit (JDK), and essential Java extensions. The Coding Pack can be used as a clean installation, or to update or repair an existing development environment.

Install the Coding Pack for Java - macOS

Note: The Coding Pack for Java is only available for Windows and macOS. For other operating systems, you will need to manually install a JDK, VS Code, and Java extensions.

Installing extensions

Java Settings For Mac

Alternatively, if you are an existing VS Code user, you can also add Java support by installing Java Extension Pack, which includes these extensions:

If JDK is not installed, the Java Extension Pack provides links to download.

You can also select which extensions you would like to install separately. The Extension Guide is provided to help you choose. You can launch the guide with the Java: Extension Guide command.

For this tutorial, the only required extensions are:

Supported Java versions

Supported versions for running VS Code for Java and supported versions for your projects are two separate concepts. To run VS Code for Java, Java SE 11 or above version is required; for projects, VS Code for Java supports projects with version 1.5 or above. For more details, refer to Configure JDK.

Installing a Java Development Kit (JDK)

Your development environment must have a Java SE Development Kit (JDK) installed. If it doesn't, you can download and install a JDK from one of these sources:

Configuring your development environment to use a JDK

Your development environment needs to know where the JDK is located. A common way to do this is setting the value of the JAVA_HOME system environment variable to the install location of the JDK, for example, C:Program FilesJavajdk-13.0.2. Or if you want to configure only VS Code to use the JDK, use the java.home setting in VS Code's User or Workspace settings.

Settings for the JDK

To access various settings for using the JDK, bring up the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)) and use the command Java: Configure Java Runtime.

The Java Extension Pack, also provides a Quick Start guide and tips for code editing and debugging. It also has a FAQ that answers some frequently asked questions. Use the command Java: Getting Started from the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)).

Note: To configure multiple JDKs, see Configure JDK. To enable Java preview features, see How can I use VS Code with new Java versions

Creating a source code file

Java Settings For Macbook Pro

Create a folder for your Java program and open the folder with VS Code. Then in VS Code, create a new file and save it with the name Hello.java. When you open that file, the Java Language Server automatically starts loading, and you should see a loading icon on the right side of the Status Bar. After it finishes loading, you will see a thumbs-up icon.

Note: If you open a Java file in VS Code without opening its folder, the Java Language Server might not work properly.

VS Code will also try to figure out the correct package for the new type and fill the new file from a template. See Create new file.

You can also create a Java project using the Java: Create Java Project command. Bring up the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)) and then type java to search for this command. After selecting the command, you will be prompted for the location and name of the project. You can also choose your build tool from this command.

Visual Studio Code also supports more complex Java projects, see Project Management.

Editing source code

You can use code snippets to scaffold your classes and methods. VS Code also provides IntelliSense for code completion, and various refactor methods.

To learn more about editing Java, see Java Editing.

Running and debugging your program

To run and debug Java code, set a breakpoint, then either press F5 on your keyboard or use the Run > Start Debugging menu item. You can also use the Run|Debug CodeLens options in the editor. After the code compiles, you can see all your variables and threads in the Run view.

The debugger also supports advanced features such as Hot Code replacement and conditional breakpoints.
