The GeometricObject and Circle classes are defined in this chapter. Analyze the following code.

public class Test {
public static void main(String[] args) {
​GeometricObject x = new Circle(3);
​GeometricObject y = (Circle)(x.clone());
​System.out.println(x);
​System.out.println(y);
}
}

◦ After you override the clone() method and make it public in the Circle class, the problem can compile and run just fine, but y is null if Circle does not implement the Cloneable interface.
◦ To enable a Circle object to be cloned, the Circle class has to override the clone() method and implement the java.lang.Cloneable interface.
◦ The program has a compile error because the clone() method is protected in the Object class.
◦ If GeometricObject implements Cloneable and Circle overrides the clone() method, the clone() method will work fine to clone Circle objects.
