1Z0-829 Handling Exceptions Practice Question
A developer wants to ensure that a block of code always executes regardless of whether an exception occurs or not, and that any exception thrown in the block is not swallowed. Which construct should be used?
⚠ Common exam trap
Many exam-takers think a catch block is required to handle exceptions, but the question specifically demands that the exception not be swallowed, making try-finally the correct choice because it executes cleanup code without interfering with exception propagation.

Correct answer & explanation
✓
try-finally
The try-finally construct ensures that the finally block always executes after the try block, regardless of whether an exception occurs, and it does not catch or swallow any exception. This meets the requirement of guaranteed execution without suppressing the exception, as the exception propagates up the call stack.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
try-catch with empty catch block
Why it's wrong here
Empty catch swallows the exception.
- ✗
try-catch-finally with catch that rethrows the exception
Why it's wrong here
Works but adds unnecessary catch; finally still runs.
- ✓
try-finally
Why this is correct
Finally runs always; exception propagates uncaught.
- ✗
try-with-resources without catch
Why it's wrong here
Resources closed automatically but exception propagates, but finally is not used.
