QUESTION 8 Assume the following classes are each defined in their own java files and compile public class A public void display { System.out.println("A's display"); public class B extends A{ public void display { System.out.println("B's display"); public class C extends A public void display { System.out.println("C's display"); public class D { public static void main(String args) { 3: int i = ((int)(Moth.random(* 10)) if (i == 0) a = new BO: else if (i == 1) a = new CO: else o = new AO: a.display: What happens when I run D? The program will not compile Around a third of the time. A's display will be printed, around a third of the time B's display will be printed, and around a third of the time C's display will be printed. A's display is always printed The program will compile, but the call to a displayd: will abort unless a = new A(): had been executed previously. The program will compile, but if a = new BO: or o = new Co: are executed, the program will abort.

Answer 1

It generates random number between 0 to 2 inclusive

And then based on the random number, it creates an object and put it in variable a and then

it calls display() methd.

So, answer is option 2

Answer:

Around a third of the time. A's display will be printed, around a third of the time B's display will be printed, and around a third of the time C's display will be printed.
