- A
public void log(String message) throws LogException { ... }
Checked exception forces caller to handle or declare.
- B
public void log(String message) { ... }
Why wrong: Cannot throw checked exception without declaration.
- C
public void log(String message) throws Error { ... }
Why wrong: Error is for serious JVM issues, not appropriate.
- D
public void log(String message) throws RuntimeException { ... }
Why wrong: RuntimeException is unchecked; callers are not forced to handle.

1Z0-829 Handling Exceptions Practice Question
This 1Z0-829 practice question tests your understanding of handling exceptions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A team is designing a logging framework. The framework's core method log(String message) may throw a checked LogException if the logging system fails. The team wants to allow callers to choose whether to handle the exception or declare it as thrown. Which declaration of the log method satisfies this requirement?
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
✓
public void log(String message) throws LogException { ... }
Option A is correct because it declares the checked exception LogException in the throws clause, which forces callers to either handle it with a try-catch or propagate it by declaring throws in their own method. This satisfies the requirement that callers can choose how to deal with the exception, as checked exceptions must be acknowledged at compile time.
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.
- ✓
public void log(String message) throws LogException { ... }
Why this is correct
Checked exception forces caller to handle or declare.

- ✗
public void log(String message) { ... }
Why it's wrong here
Cannot throw checked exception without declaration.
- ✗
public void log(String message) throws Error { ... }
Why it's wrong here
Error is for serious JVM issues, not appropriate.
- ✗
public void log(String message) throws RuntimeException { ... }
Why it's wrong here
RuntimeException is unchecked; callers are not forced to handle.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Oracle often tests the distinction between checked and unchecked exceptions, and the trap here is that candidates may think omitting throws or using RuntimeException/Error allows callers to choose, but only a checked exception declared with throws enforces the handling-or-declaring choice at compile time.
Detailed technical explanation
How to think about this question
Checked exceptions (subclasses of Exception but not RuntimeException) are part of Java's contract between method and caller; the compiler enforces that they are either caught or declared. Under the hood, the JVM does not distinguish between checked and unchecked exceptions at runtime, but the Java compiler uses the throws clause to verify exception handling at compile time. In real-world logging frameworks like Log4j or SLF4J, checked exceptions are rarely used for logging failures because they would force every logging call to handle or declare the exception, which is impractical; instead, they typically wrap failures in unchecked exceptions.
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.
