This 1Z0-829 practice question tests your understanding of handling exceptions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO statements about the try-with-resources statement are correct? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The resource class must implement AutoCloseable.
Option A is correct because the try-with-resources statement requires that each resource implements the AutoCloseable interface (or its subinterface Closeable). This interface defines the close() method, which is automatically invoked by the JVM when the try block completes, ensuring proper resource management without explicit finally blocks.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The resource class must implement AutoCloseable.
Why this is correct
Correct: only AutoCloseable resources are allowed.

Read the scenario before looking for a memorised answer.
✗
The resource variable must be declared as final.
Why it's wrong here
It is effectively final, but explicit final is optional.
✓
Resources are closed in the reverse order of their declaration.
Why this is correct
Correct: resources are closed in reverse order.

✗
A try-with-resources statement cannot have a finally block.
Why it's wrong here
It can have a finally block.
✗
Resources are closed before the try block executes.
Why it's wrong here
They are closed after the try block completes.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often think resources must be declared with the final keyword (Option B) or that finally blocks are prohibited (Option D), but the exam tests the exact JLS rules: resources are effectively final, and finally blocks are allowed but execute after resource closure.
Detailed technical explanation
How to think about this question
Under the hood, the compiler translates a try-with-resources statement into a try-finally block where each resource's close() method is called in the reverse order of declaration, as specified by JLS §14.20.3. This ensures that if one resource depends on another (e.g., a BufferedWriter wrapping a FileWriter), the wrapper is closed first, preventing data loss. A subtle behavior is that if both the try block and the close() method throw exceptions, the exception from the close() is suppressed and added to the try block's exception via Throwable.addSuppressed(), which is critical for debugging in real-world I/O operations.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 1Z0-829 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
