1Z0-811 Exception Handling and Development Tools Practice Question
A method declares throws FileNotFoundException and SQLException. Which statement about the caller is true?
⚠ Common exam trap
Test-takers frequently think they can choose to handle only one exception or ignore checked exceptions entirely, forgetting that Java's checked exception mechanism requires every declared checked exception to be either caught or re-declared by the caller.

Correct answer & explanation
✓
The caller must handle or declare both exceptions.
In Java, when a method declares checked exceptions (like FileNotFoundException and SQLException) in its throws clause, any caller must either handle each checked exception with a try-catch block or declare them in its own throws clause. The compiler enforces this rule to ensure that checked exceptions are properly accounted for, preventing unhandled checked exceptions from propagating unchecked.
