1Z0-811 Exception Handling and Development Tools Practice Question
Which TWO statements about the finally block are true? (Choose two.)
⚠ Common exam trap
It's easy for candidates to think the finally block only runs when an exception occurs (Option B) or that it cannot contain a return statement (Option D), but the exam tests the precise behavior that finally always executes and can contain return statements, albeit with side effects.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A try block must be followed by either a catch or finally.
A try block must be followed by at least one catch block or a finally block in Java. Option C is correct because the finally block is intended for resource cleanup code that always executes, regardless of whether an exception occurs. Options B, D, and E are false: B because finally always executes unless the JVM exits; D because finally can contain a return statement (though not recommended); E because finally executes after the catch block only when a catch block is invoked—if no exception occurs, there is no catch block, so the statement is not universally true.

Why it's wrong here
Incorrect. The finally block can contain a return statement, though it may suppress exceptions.
