The correct answer is that the exception types in a multi-catch block must be disjoint, meaning they cannot share a subtype relationship. This rule exists because if one exception is a subclass of another, the catch block would become ambiguous—the broader exception would always catch the narrower one first, making the multi-catch syntax redundant and violating type safety. On the Oracle Certified Professional Java SE 17 Developer 1Z0-829 exam, this concept tests your understanding of exception hierarchy and compile-time checking; a common trap is assuming you can list related exceptions like IOException and FileNotFoundException together. Remember that a multi-catch block can also be combined with a finally block, and the catch variable is implicitly final, so you cannot reassign it. For a quick memory tip: think of multi-catch as a family reunion where you can only invite cousins, not parents and children—no subtype relations allowed.
1Z0-829 Handling Exceptions Practice Question
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 multi-catch blocks are correct?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A multi-catch block can be used with a finally block.
Option B is correct because the exception types in a multi-catch block must be disjoint (no subtype relationship). Option D is correct because a multi-catch block can be combined with a finally block. Option A is wrong because multi-catch can catch both checked and unchecked exceptions. Option C is wrong because the variable in a multi-catch block is implicitly final. Option E is wrong because multi-catch can be used with any try, not only try-with-resources.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Multi-catch can catch both checked and unchecked exceptions.
✓
A multi-catch block can be used with a finally block.

✗
The variable in a multi-catch block is not implicitly final.
Why it's wrong here
The multi-catch variable is implicitly final.
✗
A multi-catch block can only be used with try-with-resources.
Why it's wrong here
Multi-catch can be used with any try constructs.
✓
The exception types in a multi-catch block must be disjoint.
Why this is correct
Multi-catch types must be disjoint to avoid catching the same exception twice.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
