Error running simple program in NetBeans 9.0

Question

I'm trying to use NetBeans for a JDBC project. However, I'm getting runtime errors when I try to compile. I decided to try a "hello world" project and I couldn't get that to run also. I'm in NetBeans 9.0 with Java JDK 10.0.2.

Error Message:

Exception in thread "main" java.lang.RuntimeException:

C:\Users\James\AppData\Local\NetBeans\Cache\dev\executor-snippets\run.xml:111: The following error occurred while executing this line:

public class JavaApplication2 {


public static void main(String[] args) {


    System.out.println("Hello");
}

}

Answer 1

It is very easy, your JDK version is not 100 % compatible; use version 8.2, which is the most stable for Arduino and others.

To change platforms without deleting the existing one, simply go to Tools / Java Platforms / click on the button add Platforms.
