Explanations “Top Java Quiz Questions”

What does the class output?

❌ A. LOKI
❌ B. OKLI
✅ C. OLKI
❌ D. OKIL
❌ E. The output cannot be determined until runtime
❌ F. Nothing; the code does not compile
❌ G. None of the above

Explanation:
The code compiles and runs without issue, so options E and F are incorrect. Since Sidekick correctly implements AutoCloseable, it can be used in a try-with-resources statement. The first value printed is O on line 9. For this question, you need to remember that a try-with-resources statement executes the resource’s close() method before a programmer-defined finally block. For this reason, L is printed on line 5. Next, the finally block is expected, and K is printed. The requiresAssistance() method ends, and the main() method prints I on line 16. The combined output is OLKI, making option C the correct answer.
