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 true? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Resources declared in the try-with-resources block are closed automatically.
Option C is correct because the try-with-resources statement automatically closes each resource declared in the resource specification after the try block completes, whether normally or abruptly. This is the primary purpose of the construct: to ensure reliable resource cleanup without requiring an explicit finally block.
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 resources must implement the Closeable interface.
Why it's wrong here
Incorrect: Resources must implement AutoCloseable, which is a superinterface of Closeable.
✗
Resources can be reassigned inside the try block.
Why it's wrong here
Incorrect: Resources declared in try-with-resources are effectively final and cannot be reassigned.
✓
Resources declared in the try-with-resources block are closed automatically.
Why this is correct
Correct: The try-with-resources statement ensures each resource is closed at the end of the statement.

✓
Resources are closed in the reverse order of their declaration.
Why this is correct
Correct: Resources are closed in reverse order to avoid dependency issues.

✗
Multiple resources are separated by commas.
Why it's wrong here
Incorrect: Multiple resources are separated by semicolons.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the required interface (AutoCloseable vs. Closeable) and the separator between multiple resources (semicolons vs. commas), leading them to select the plausible-sounding but incorrect options A and E.
Detailed technical explanation
How to think about this question
Under the hood, the try-with-resources statement compiles to a try-finally block where each resource's close() method is called in the reverse order of declaration, and any exceptions thrown during close() are suppressed if an exception is already propagating. This suppression mechanism uses the Throwable.addSuppressed() method, which is critical for debugging when multiple failures occur. In real-world scenarios, such as managing database connections and statements, the reverse closing order ensures that dependent resources (e.g., ResultSet before Statement before Connection) are closed correctly.
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.
