Hello,

I am new to Java. I create a reference variable, and then call a final method on that variable but on compilation I get this error:

java: <identifier> expected

pointing to the last line - p.sing();

This is my code:

class MyClass{
    public static void main(String[] args){

    }
}

class Person {
    final void sing() {
        System.out.println("la..la..la..");
    }
}
class Professor {
    final void singalong() {
        System.out.println("la..la..la..");
    }
    Person p = new Person();
    p.sing();
}

What does the error mean? What identifier needs to be present on that line p.sing();???

Thanks,

Marc
