What will be the output of the program?
public class HorseTest
{
public static void main (String [] args)
{
class Horse
{
public String name; /* Line 7 */
public Horse(String s)
{
name = s;
}
} /* class Horse ends */
Object obj = new Horse("Zippo"); /* Line 13 */
Horse h = (Horse) obj; /* Line 14 */
System.out.println(h.name);
}
} /* class HorseTest ends */
Answer: B
The code in the HorseTest class is perfectly legal. Line 13 creates an instance of the method-local inner class Horse, using a reference variable declared as type Object. Line 14 casts the Horse object to a Horse reference variable, which allows line 15 to compile. If line 14 were removed, the HorseTest code would not compile, because class Object does not have a name variable.
