Explanations “Top Java Quiz Questions”

Which statement about the code is true?

❌ A. It compiles and prints abc
❌ B. It compiles and prints abd
❌ C. It compiles and prints abcd
❌ D. One line contains a compiler error
❌ E. Two lines contain a compiler error
✅ F. Three lines contain a compiler error
❌ G. It compiles but prints an exception at runtime

Explanation:
Line 5 does not compile as the FileNotFoundException thrown on line 12 is not handled or declared by the method.
Line 7 does not compile because StringBuilder does not implement AutoCloseable and is therefore not compatible with a try-with-resource statement.
Finally, line 10 does not compile as RuntimeException is a subclass of Exception in the multi-catch block, making it redundant. Since this method contains three compiler errors, option F is the correct answer.
