What will be the output of the following program?
import java.util.*;
class Shape {
int value;
public Shape(int value) {
this.value = value;
}
public int shape() {
return value + value;
}
}
class Car extends Shape {
public Car(int value) {
super(value);
}
public int shape() {
return value * value;
}
}
public class SuperClassAndSubClass {

shapes.add(new Car(12)); shapes.add(new Car(2));
Car[] shapesArray = new Car[2];
shapesArray[0] = new Car(12); shapesArray[1] = new Car(2);
SuperClassAndSubClass object = new SuperClassAndSubClass();
object.printShapesArray(shapesArray);
object.printShapesList(shapes);
}
