I can tell you for Windows   Install Java Extension Pack and Code Runner Extension from VS Code Extensions   Edit your java home location in VS Code settings   quot java home quot    quot C   Program Files  Java  jdk-9 0 4 quot    Check if javac is recognized in VS Code internal terminal  If this check fails  try opening VS Code as administrator   Create a simple Java program in Main java file as    public class Main       public static void main String   args            System out println  quot Hello world quot                   Note  Do not add package in your main class    Right click anywhere on the java file and select run code   Check the output in the console    Done  hope this helps
