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 { public static void main(String[] args) { _______________ frog = new Circle(); } } public class Square extends Shape {} public class Circle extends Shape {}
A, B, D, E.
The blank can be filled with any class or interface that is a super type of TurtleShape.
A is a superclass of Circle, and B is the same class, so both are correct.
Square is not a superclass of Circle, so C is incorrect.
Circle inherits the Printable interface, so D is correct.
All classes inherit Object, so E is correct.
Finally, Long is an unrelated class that is not a superclass of Circle, and it is therefore incorrect.
