it works now. There comes an extra java-taskbar. And it opens a strange object, who looks like a television with the gamefield

ok thanks, the application runs now. but it just shows this: "C:\Program Files\Java\jdk-14.0.1\bin\java.exe" Is it normal for this time? I am only at task 8. I thought, I can see the Gamefield with its cells.

No, that's not normal and as expected you should see the gamefield. As said already below, JavaFX was bundeld to Java till (including) version 10. So here you have no problems installing it and setting up the IDE. It just runs out of the box. So I'd suggest to install an older LTS JDK like v8. And that's the version the validator is using, too. So you do not lose functionality but gain compatibility. When this is running and you later need it, you can switch to a higher version. IntelliJ even allows them to run parallel. So you just can switch the version for one project.

useful

Have you adapted the vm options of IntelliJ https://www.jetbrains.com/help/idea/javafx.html#vm-options

Since Java 11 (afaik) JavaFX isn't bunded to Java anymore and you need to install it separately (or use an older Java version, 8+ should do for Codegym). https://openjfx.io/
