+## Getting Started
+
+Welcome to the VS Code Java world. Here is a guideline to help you get started to write Java code in Visual Studio Code.
+
+## Folder Structure
+
+The workspace contains two folders by default, where:
+
+- `src`: the folder to maintain sources
+- `lib`: the folder to maintain dependencies
+
+Meanwhile, the compiled output files will be generated in the `bin` folder by default.
+
+> If you want to customize the folder structure, open `.vscode/settings.json` and update the related settings there.
+
+## Dependency Management
+
+The `JAVA PROJECTS` view allows you to manage your dependencies. More details can be found [here](https://github.com/microsoft/vscode-java-dependency#manage-dependencies).

RGBColours/src/App.java

+public class App {
+    public static void main(String[] args) throws Exception {
+        System.out.println("a");
+        Colour Yellow = new Colour(255,255,0);
+        Colour Purple = new Colour(128,0,128);
+        Colour Orange = new Colour(255,165,0);
+    }
+}

RGBColours/src/Colour.java

+// Ex 1.4
+public class Colour {
+    int red;
+    int green;
+    int blue;
+
+    public Colour(int red2, int green2, int blue2){
+        this.red = red2;
+        this.green = green2;
+        this.blue = blue2;
+    }
+}
