Which of the following statements can be inserted in the blank line so that the code will compile successfully? (Choose all that apply)
public interface Printable {
}
public class Shape implements Printable {
}
class Rectangle extends Shape {
}
public class Main {
public static void main(String[] args) {
List<Rectangle> rectangles = new ArrayList<Rectangle>();
for(Shape s : rectangles) {
___________ myShape = s;
}
}
}
A, C, E.
The for-each loop automatically casts each Rectangle object to an Shape reference.
Any parent class or interface that Shape inherits from is permitted without an explicit cast.
A and E are correct.
C is correct since the reference is being cast to the same type, so no explicit cast is required.
B is incorrect, since Long is not a parent of Shape.
D is incorrect, an explicit cast to Rectangle on the right-hand side of the expression is required.
