Protected methods in the same package (what about module)

[Mike Grabl-j]

Java 14

Cookie.java

package bakery;

class Bakery{
        String name = "Sam";
        public Bakery(){
            print();
        }

        protected void print(){
                System.out.println("test");
        }
}

public class Cookie extends Bakery{
        protected void print(){
                System.out.println(name);
        }       
}

Ex4.java

package bakery;

public class Ex4 {
    public static void main(String [] args){
        System.out.print("test");       
        Cookie c = new Cookie();
        c.print();      
    }
}

Problem
Well, The package seems to be tha same: bakery. Why it is not run? It is angry about modules. I've not studied modules yet. Could you help me understand how to correct the code for it to compile and run.

I don't get an error when I execute Ex4.  I get this output:

Ex4 wrote:testSam
Sam

I used the following to execute:
javac bakery/Ex4.java bakery/Cookie.java java bakery.Ex4
