1Z0-811 Exception Handling and Development Tools Practice Question
This 1Z0-811 practice question tests your understanding of exception handling and development tools. 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 THREE are checked exceptions in Java? (Choose three.)
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
✓
SQLException
SQLException is a checked exception in Java because it extends Exception directly (not RuntimeException). Checked exceptions must be either caught with a try-catch block or declared in the method signature using the throws clause. SQLException is thrown when there is a database access error or other SQL-related issues, forcing the developer to handle potential failures at compile time.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Oracle often tests the distinction between checked and unchecked exceptions by including common RuntimeException subclasses (like NullPointerException and ArrayIndexOutOfBoundsException) as distractors, exploiting the misconception that any exception must be handled.
Detailed technical explanation
How to think about this question
Checked exceptions are subclasses of Exception but not of RuntimeException. The Java compiler enforces that checked exceptions are either caught or declared, promoting robust error handling for recoverable conditions like file I/O or database failures. Under the hood, the compiler checks the throws clause and try-catch blocks during compilation; if a checked exception is not handled, the code will not compile. In real-world scenarios, failing to handle SQLException could leave database connections open or transactions incomplete, leading to resource leaks.
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 1Z0-811 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.
