call subclass method in superclass but not the other class

[Jack Lau]

Hello,

If there is a private method in subclass and I want to call it in the superclass, however, I want the subclass method only called by superclass. I know I can add one public method in subclass and called by superclass but it also cause a security issue.....does anyone know how to do?

public class SuperClass {
    final void a() {
        m();    
    }
    protected abstract void m();
 
}
 
public class SubClass {
    
    private void m() {}
 
    // in main
    // call a();
}

Thanks,
Jack
