followed the steps in the cheat sheet for HelloWorld
getting a HelloWorld.class in the /bin dir

HelloWorld.java code is

public class HelloWorld {

public static void main(String[] args) {
// TODO Auto-generated method stub

System.out.println("Hello world!");

}

}

get the following error
"Error occurred during initialization of boot layer
java.lang.module.FindException: Error reading module: C:\Users\Public\Athena\eclipse-workspace\HelloWorld\bin
Caused by: java.lang.module.InvalidModuleDescriptorException: HelloWorld.class found in top-level directory (unnamed package not allowed in module)"

the [b]module-ingfo.java[/b }that was created has this in it
module HelloWorld {
}

What am I missing ?

Hi,

Try to create a package (e.g. mypackage ) and move your class to it (you can use refactor).

or

delete module-info.java if you have one.

Regards.

You are welcome,
May I suggest some reading first.
https://docs.oracle.com/javase/tutorial/

At this stage, I think that you can skip module-info.java
Search for module-info.java later on.

Also, I sugest you start using packages you can read about it in the The Java™ Tutorials .

Regards.
Eitan.
