A combination of runtime properties and coding changes that targeted Mac OS X specific APIs made a big difference to that audience. Recall that Mac OS X is a melding of two worlds. Hard core UNIX programmers can pop open a Terminal window and write their Java code using vi and compile and run it from the command line.

Support for Java in Visual Studio Code is provided through a wide range of extensions. Combined with the power of core VS Code, these extensions give you a lightweight and performant code editor that also supports many of the most common Java development techniques.

This article will give you an overview of different capabilities of Visual Studio Code for Java developers. For a quick walkthrough of editing, running, and debugging a Java program with Visual Studio Code, use the button below.

Overview

VS Code provides essential language features such as code completion, refactoring, linting, formatting, and code snippets along with convenient debugging and unit test support. VS Code also integrates with tooling and frameworks such as Maven, Tomcat, Jetty, and Spring Boot. Leveraging the power of Visual Studio Code, Java developers get an excellent tool for both quick code editing and also the full debugging and testing cycle. It's a great choice for your Java work if you're looking for a tool which:

  • Is fast, lightweight, free, and open source.
  • Supports many other languages, not just Java.
  • Helps start your Java journey without installing and learning a complex IDE.
  • Provides great microservices support including popular frameworks, container tooling, and cloud integration.
  • Offers team-based collaboration features such as Visual Studio Live Share.
  • Improves your productivity through IntelliSense and other code-aware editing features.

Install Visual Studio Code for Java

VS Code is a fast editor and ships with great editing features. Before you begin, you must have the Java SE Development Kit (JDK) on your local environment. 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.

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.

ICloud, however, involves slower progression, with the second step reaching 50GB. You can then access this file from any other device logged in to your account. Dropbox for mac free download. Simple symbols, such as a blue circle to show syncing and a green tick to show completion, mean you don’t need to be tech-savvy to complete tasks.Although the free storage is a good way to try out Dropbox, you'll have to take a large leap to enjoy the next level of storage of 1TB.

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.

Alternatively, you can also add Java language support to VS Code by installing the popular Java extensions by yourself.

Download VS Code - If you haven't downloaded VS Code yet, quickly install for your platform (Windows, macOS, Linux).

To help set up Java on VS Code, there is a Java Extension Pack, which contains the most popular extensions for most Java developers:

There are also other popular Java extensions you can pick for your own needs, including:

Thanks to the great Java community around VS Code, the list doesn't end there. You can search for more Java extensions easily within VS Code:

  1. Go to the Extensions view (⇧⌘X (Windows, Linux Ctrl+Shift+X)).
  2. Filter the extensions list by typing 'java'.

This document describes some of the key features included in those Java extensions.

Getting started

NOTE: If you are using VS Code on Windows and want to take advantage of the Windows Subsystem for Linux, see Developing in WSL.

For developers new to Java or new to VS Code, we provide a Getting Started experience. Once you've installed the Java Extension Pack, you can open the Getting Started experience from within VS Code with the Java: Getting Started command from the Command Palette. Open the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)) and type 'Java: Getting Started'.

Working with Java source files

You can use VS Code to read, write, run, and debug Java source file(s) without creating a project. VS Code for Java supports two modes, lightweight and standard. Lightweight mode is ideal for scenarios that only deal with source file(s). If you want to work with a full scale project, standard mode will be required. You can easily switch from lightweight mode to standard mode, when needed. To learn more, see Lightweight Mode.

Working with Java project

There are three things you must understand to work with Java in VS Code:

  1. How does VS Code handle Workspaces?
  2. How does VS Code handle Java?
  3. How does VS Code handle Workspaces that contain Java?

VS Code Workspaces

In Visual Studio Code, a 'Workspace' means a collection of one or more filesystem folders (and their children) and all of the VS Code configurations that take effect when that 'Workspace' is open in VS Code. There are two kinds of 'Workspaces' in VS Code, 'folder workspaces' and 'multi-root workspaces'.

A 'folder workspace' is presented by VS Code when you open a filesystem folder (directory) in VS Code.

A 'multi-root workspace' can refer to multiple folders (directories) from disparate parts of the file system and VS Code displays the contents of the folder(s) of the workspace together in the File Explorer. To learn more, see Multi-root Workspaces.

Java project in VS Code

In contrast to IDEs such as IntelliJ IDEA, NetBeans, or Eclipse, the concept of a 'Java project' is provided entirely by extensions, and is not a core concept in the base VS Code. When working with 'Java projects' in VS Code, you must have the necessary extensions installed to work with those project files.

Coding

For example, Maven, Eclipse, and Gradle Java projects are supported through Language Support for Java(TM) by Red Hat, by utilizing M2Eclipse, which provides Maven support, and Buildship, which provides Gradle support through the Eclipse JDT Language Server.

With Maven for Java, you can generate projects from Maven Archetypes, browse through all the Maven projects within your workspace, and execute Maven goals easily from an embedded explorer. Projects can also be created and managed with the Project Manager for Java extension.

Visual Studio Code also supports working with standalone Java files outside of a Java project, described in the Java Tutorial with VS Code.

VS Code Workspaces that contain Java project

Assuming the necessary Java extensions are installed, opening a VS Code workspace that contains Java artifacts will cause those extensions to understand those artifacts and present options for working with them.

More details about Java project support can be found in Java Project Management in Visual Studio Code and Build Tools.

Editing

Code Navigation

Java in Visual Studio Code also supports source code navigation features such as search for symbol, Peek Definition, and Go to Definition. The Spring Boot Tools extension provides enhanced navigation and code completion support for Spring Boot projects.

One of the key advantages of VS Code is speed. When you open your Java source file or folder, within a few seconds, with the help of Lightweight Mode, you will be able to navigate your code base with Outline view as well as commands such as Go to Definition and Go to Reference. This is especially useful when you open a project for the first time.

Code Completion

IntelliSense is a general term for language features, including intelligent code completion (in-context method and variable suggestions) across all your files and for built-in and third-party modules. VS Code supports code completion and IntelliSense for Java through Language Support for Java(TM) by Red Hat. It also provides AI-assisted IntelliSense called IntelliCode by putting what you're most likely to use at the top of your completion list.

See also in Java Code Navigation and Editing. VS Code also supports a range of Refactoring and Linting features.

Debugging

Debugger for Java is a lightweight Java Debugger based on Java Debug Server. It works with Language Support for Java by Red Hat to allow users to debug Java code within Visual Studio Code.

Starting a debugging session is easy, click on the Run Debug button available at the CodeLens of your main() function, or press F5. The debugger will automatically generate the proper configuration for you.

Although it's lightweight, the Java debugger supports advanced features such as expression evaluation, conditional breakpoints, and hot code replacement. For more debugging related information, visit Java Debugging.

Testing

With the support from the Java Test Runner extension, you can easily run, debug, and manage your JUnit and TestNG test cases.

For more about testing, read Testing Java.

Spring Boot, Tomcat, and Jetty

To further improve your Java productivity in VS Code, there are extensions for most popular frameworks and tools such as Spring Boot, Tomcat, and Jetty created by the community.

The Tomcat extension includes an explorer to easily navigate and manage your Tomcat servers. You can create, start, debug, stop, and rename your Tomcat server with the extension.

See Application Servers to learn more about support for Tomcat and Jetty as well as other application servers with VS Code.

Spring Boot support is provided by Pivotal. There are also Spring Initializr Java Support and Spring Boot Dashboard extensions available from Microsoft to further improve your experience with Spring Boot in Visual Studio Code.

See Spring Boot with VS Code to learn more about Spring Boot support with VS Code.

Hello, World in Java on Mac OS X


This documents instructs you on how to setup a Java programmingenvironment for your Mac OS X computer and provides a step-by-stepguide to creating, compiling, and executing a Java program.We assume you are running at least OS X 10.2.3.All of the software is freely available on the Web.

Java Coding Format

Java

You will use the Java compiler javac to compile your Java programs andthe Java interpreter java to run them.Mac OS X includes implementation of Java 2 Standard Edition (J2SE) 1.4.1,so there is nothing to do in this step.

Command line interface

You will type commands in an application called the Terminal.You might enjoy reading Neal Stephenson's light-heartedessay In the Beginningwas the Command Line.

  • Open a terminal window. You can find this underGo -> Applications -> Utilities. Drag the Terminal to your dock sinceyou will be using it frequently.
  • You should now have a Terminal window somewhere on the screen.It will have a command prompt that looks something like:
  • To check that you have the right version of Java installed, typethe text in boldface below.
    If Java is installed, you should see something like:
    Now, check that the Java compiler is accessible.
    If it is installed, you should see something like
    If not, install the Developers Tools CD that came with your Mac anduse Software Update to make sure you have the latest version.
  • Now, create a directory to store your Java programs.In the window containing the Command Prompt, type the bold commandsbelow:
    The mkdir command creates a new directory;the cd command changes the current working directory.After executing these commands, your working directoryis the newly created ~username/introcs/hello/. All of yourfiles for Assignment 0 will go here.Don't be scared by the Terminal - you will only need to use afew basic commands. Keep this window open since you will need it laterin the assignment.
  • Since you will be using the Terminal frequently, we recommend customizingWe recommend customizing the default settings..

Text Editor

You will type and edit your programs in a text editor called JEdit.JEdit is similar to conventional word processors like MS Word,but it features many specialized programming tools includingsyntax highlighting, bracket matching, auto indenting, indentshifting, line numbering, and commenting out code. It's even written in Java.

  • Downloadthe latest stable version of JEdit using the MacOSX package link.
  • We recommend the following JEdit customizations.
    • Enable Mac OS style menubar inUtilities -> Global Options -> Plugins -> Mac OS Settings
    • Change the default indentation to four spaces viaUtilities -> Global Options -> Editing -> Indent Width andUtilities -> Global Options -> Editing -> Tab Width. Global Options -> Editing -> Soft tabs.-->
    • Change the default tab width when printing to four spaces viaUtilities -> Global Options -> Printing -> Tab width when printing
    • Add line numbers by checking Utilities -> Global Options -> Gutter -> Line Numbering
    • Allow at most 80 characters per line byUtilities -> Global Options -> Editing -> Word wrap -> hard andUtilities -> Global Options -> Editing -> Wrap margin -> 80.
    • Change the default line separator to Unix viaUtilities -> Global Options -> Loading & Saving -> Default Line Separator
    • Remove the annoying . that marks the end of a line by uncheckingUtilities -> Global Options -> Text Area -> End of Line Markers
  • To associate .java files with JEdit so that when you double-click a .java file,it opens it in JEdit:
    • Right click a .java file (or click then shift-right click it if using Windows NT)
    • Choose Open With..
    • Select JEdit from the list of programs or locate JEdit by selecting Otherif necessary.
    • Check the Always use this program to open this file type box
Apple purists may prefer Project Builder which can be found in the Findervia

Why Mac For Coding

Computer -> OS X Partition -> Developer -> Applications -> Project Builder.
Create the program

Now you are ready to write your first Java program.

  • Launch JEdit Start -> jEdit.
  • In the JEdit window, type the Java program exactly as it appears below.If you omit even a semicolon, the program won't work.
  • When you're done, save the program usingFile -> Save As, chose the directory C:introcshelloand type in the file name HelloWorld.java.The file name is case sensitive and must exactly match the name of the classin the Java program. Don't forget to include the .java extension in thefile name.
Compile the program

It is now time to convert your Java program into a form more amenable for executingon a computer.

  • From the Command Prompt, type
    If javac complains in some way, you mistyped something, and you should check your program carefully. Ask for help if you can't see the mistake.
  • If everything went well, you should see the followingin the Command Prompt:
    Silence is golden in computer science.
Execute the program

Now it is time to run your program. This is the fun part.

  • At the Command Prompt, type
  • If all goes well, you should see
  • You may need to repeat this edit-compile-execute cycle a few times before it all goes smoothly.Use the up and down arrow keys to repeat previous commands and avoid extra typing.
