About Question enthuware.ocpjp.v11.2-.-1770 :

[ACV001]

I have tried the example and it compiles perfectly. Can you please double check? It uses types from Food class. If you call it like Eatable.types = 30 - then you get an error that you cannot reassign final variable (which types in Eatable is).

Problem statement:

What will the following code print when compiled and run?

Code: Select all

interface Eatable{     int types = 10; } 
class Food implements Eatable {     public static int types = 20; } 
public class Fruit extends Food implements Eatable{  //LINE1          
 public static void main(String[] args) {         
   types = 30; //LINE 2         
   System.out.println(types); //LINE 3     
}
}

Please copy the code exactly as given in the problem statement. There is no "types" defined in Food class.

Thanks,

I've updated the question with the exact problem statement and there is a field types.

However, interestingly enough, Intellij didn't report this as a compilation problem until I actually tried to run the code.

When rebuild was done the following error popped up:

"java: reference to types is ambiguous"

So it is not a problem. Thanks
