Explanations “Top Java Quiz Questions”

What is the output of the code?

✅ A. SpiderArthropod
❌ B. ArthropodSpider
❌ C. SpiderSpider
❌ D. ArthropodArthropod
❌ E. The code will not compile because of line 5
❌ F. The code will not compile because of line 9

Explanation:
The code compiles and runs without issue, so options E and F are incorrect. The printName() method is an overload in Spider, not an override, so both methods may be called. The call on line 8 references the version that takes an int as input defined in the Spider class, and the call on line 9 references the version in the Arthropod class that takes a double. Therefore, SpiderArthropod is output and option A is the correct answer.
