two possible answers Q18 ch 4 page 282 from KB

[Barkat Mardhani]

If the code presents an statement that will give compilation error and another statement that might throw runtime error, but question says pick one answer, than what should be answered:
Here is the code:

1. public class Test {
2. public static int y;
3. public static void foo(int x) {
4. System.out.print("foo ");
5. y = x;
6. }
7. public static int bar(int z) {
8. System.out.print("bar ");
9. return y = z;
10. }
11. public static void main(String [] args ) {
12. int t = 0;
13. assert t > 0 : bar(7);
14. assert t > 1 : foo(8);
15. System.out.println("done ");
16. }
17. }

The answer is compilation error at line 14. But I guess there is runtime error at line 13 as well.

Ok, why do you think there's a runtime error?
foo() is void, so there's a compiler error, since the second expression of the assertion must return a value.
let me know...

Hi Barkat
First if there is only one possible answer select the one that says does not compile. If they want two answers select the other one. But it sounds absurd to ask for a runtime error along with a compilation error. How can you ever have a runtime error when you can not even compile the program.
Secondly which error are you talking about. I only encountered an AssertionError(after removing the compilation error).
For this question I would say that the answer should be compilation error alongwith any other suitable answer(if any). Runtime error at line 13 is wrong.

The AssertaionError is the runtime error I am talking about.

Hi Barkat

The answer is compilation error at line 14. But I guess there is runtime error at line 13 as well.

It is not possible for the code to even compile how can it have an AssertionError.
