## Getting Started
2+
3+
Welcome to the VS Code Java world. Here is a guideline to help you get started to write Java code in Visual Studio Code.
4+
5+
## Folder Structure
6+
7+
The workspace contains two folders by default, where:
8+
9+
- `src`: the folder to maintain sources
10+
- `lib`: the folder to maintain dependencies
11+
12+
Meanwhile, the compiled output files will be generated in the `bin` folder by default.
13+
14+
> If you want to customize the folder structure, open `.vscode/settings.json` and update the related settings there.
15+
16+
## Dependency Management
17+
18+
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).
