Explanations “Top Java Quiz Questions”

Choose the correct statement about the code

✅ A. It compiles without issue
❌ B. The code will not compile because of line 2
❌ C. The code will not compile because of line 4
❌ D. The code will not compile because of line 5
❌ E. The code will not compile because of lines 2 and 5
❌ F. The code will not compile because the class Falcon doesn’t implement the interface methods

Explanation:
Although the definition of methods on lines 2 and 5 vary, both will be converted to public abstract by the compiler. Line 4 is fine, because an interface can have public or default access. Finally, the class Falcon doesn’t need to implement the interface methods because it is marked as abstract. Therefore, the code will compile without issue.
