Selected Answer: B
Tested, answer is B. Source code to test: public static void main(String[] args) { Short s1 = 200; Integer s2 = 400; String s3 = (String) (s1 + s2); // line n1 Long s4 = (long) s1 + s2; // line n2 System.out.println("Sum is " + s3); } A correct convert to string could be: String s3 = String.valueOf(s1 + s2);

Correct is B. Because the ClassCastException is a RuntimeException and it may not affect compilation. But here ceompilation fails at n1.

Selected Answer: B
Correct is B. Because the ClassCastException occurs when we try to cast to a PRIMITIVE variable type that does not hold the variable's value. String is not a primitive type and a primitive type cannot cast to a non-primitive type, error occurs when executing code on line n1.
