When you run that JAR file, Java starts your application by reading that main-class entry, because you need the main method to execute Java programs. With lightweight mode, only source files and JDK are resolved by the language server with standard mode, imported dependencies are resolved and the project is built by the language server.The main difference between normal and executable JAR file is that later contains a manifest file, which specifies a main-class entry.

You can directly import existing Java projects and modules to your workspace through File > Open Folder. During creation, VS Code will facilitate installing required extension(s) per your project type, if the extension(s) weren't already installed. in Command Palette ( ⇧⌘P (Windows, Linux Ctrl+Shift+P)). You can create a new Java project by clicking the + button in the navigation bar, or through the command: Java: Create Java Project. There are also many useful features in each node's context menu, you can right-click on the node in Explorer to toggle it out. You can find buttons next to the nodes in the Explorer, which provide useful shortcuts for some actions. For example, you can switch between hierarchical view and flat view.
