SCJP - 15 -Given Example

What is the result?
A. Clidlet
B. Clidder
C. Clidder
Clidlet
D. Clidlet
Clidder
E. Compilation fails.

Answer:

A is correct. Although a final method cannot be overridden, in this case, the method is
private, and therefore hidden. The effect is that a new, accessible, method flipper is created.
Therefore, no polymorphism occurs in this example, the method invoked is simply that of
the child class, and no error occurs.

B, C, D, and E are incorrect based on the preceding.
(Objective 5.3)
==

class Clidder {
private final void flipper() { System.out.println("Clidder"); }
}
public class Clidlet extends Clidder {
public final void flipper() { System.out.println("Clidlet"); }
public static void main(String [] args) {
new Clidlet().flipper();
} }
