Write Java Code in Visual Studio Code

Last updated on 9 Sep, 2022

Visual Studio is a free and light weight IDE maintained by Microsoft. It has good support for Java programming language.

VS Code does not install JDK for you. You can install it separately using tools like Amazon Corretto.

If you do not have VS code installed, download and install it first.

Next, we need to find and install Extension Pack for Java.

Extension pack for Java

HelloWorld Java

Create a folder anywhere to store the Java files. Open the folder in VS Code.

Create a new file HelloWorld.java and paste below content.

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

VS Code comes with a terminal. Open a new terminal. Run below command to build the Java code.

javac HelloWorld.java

If the build is successful, you can see a HelloWorld.class created. Next we can run the program using:

java HelloWorld

We can find the output like below:
