Got it, let's get your IntelliJ IDEA and VS Code set up for JavaFX so you can ditch those tedious command-line commands. Here's the straightforward, step-by-step configuration for both IDEs:

• Open your IntelliJ IDEA, create a new JavaFX project or open your existing school project.
• Go to File → Project Structure (or use the shortcut Cmd + ; on macOS).
• In the left sidebar, select Project:
  • Make sure the Project SDK is set to your installed jdk-11.0.2.jdk.
  • Set Project language level to 11 - Local variable syntax for lambda parameters.
• Next, select Libraries in the left sidebar:
  • Click the + icon → choose Java, then navigate to the lib folder of your JavaFX SDK (e.g., /Library/Java/JavaVirtualMachines/javafx-sdk-11.0.2/lib). Select the folder itself, then click OK to add it as a library.
• Now configure the run environment:
  • Click the run configuration dropdown in the top-right corner → select Edit Configurations.
  • Choose your JavaFX main class's run configuration (or create a new one if needed).
  • In the VM options field, paste this line (adjust the path if your JavaFX SDK is in a different location):

    --module-path /Library/Java/JavaVirtualMachines/javafx-sdk-11.0.2/lib --add-modules javafx.controls,javafx.fxml
    

    Note: If you don't use FXML in your project, you can remove ,javafx.fxml.
• Save the configuration, then click the run button—your JavaFX app should launch without any extra command-line steps!

First, make sure you have the Java Extension Pack installed (it includes all the necessary tools for Java development in VS Code).

• Open your JavaFX project folder in VS Code.
• Create a new folder named .vscode in your project root directory. Inside this folder, create two files: settings.json and launch.json.
• Configure settings.json with these contents (update paths to match your JDK and JavaFX SDK locations):

  {
      "java.home": "/Library/Java/JavaVirtualMachines/jdk-11.0.2.jdk/Contents/Home",
      "java.project.referencedLibraries": [
          "/Library/Java/JavaVirtualMachines/javafx-sdk-11.0.2/lib/*.jar"
      ]
  }
  

• Configure launch.json (replace your.full.main.class.name with your actual main class's fully qualified name, like com.schoolproject.HelloFx):

  {
      "version": "0.2.0",
      "configurations": [
          {
              "type": "java",
              "name": "Launch JavaFX App",
              "request": "launch",
              "mainClass": "your.full.main.class.name",
              "vmArgs": "--module-path /Library/Java/JavaVirtualMachines/javafx-sdk-11.0.2/lib --add-modules javafx.controls,javafx.fxml"
          }
      ]
  }
  

• Save both files. Go to the Run and Debug tab (click the bug/play icon in the left sidebar, or use Ctrl+Shift+D), select the "Launch JavaFX App" configuration, and click the play button to run your app.

Quick Tip #

If you ever update your JDK or JavaFX SDK version, just remember to update the paths in these configurations to match the new locations!
