1Z0-829 Handling Exceptions Practice Question
Exhibit
Refer to the exhibit. Execution output: Exception in thread "main" java.io.IOException: IO error at Test.main(Test.java:10) Suppressed: java.io.IOException: Close error at Test$MyResource.close(Test.java:20)
Given the exhibit showing output from a program that uses try-with-resources, which of the following best describes the program?
⚠ Common exam trap
Oracle often tests the misconception that only one exception can be thrown, leading candidates to think that if a close method throws, the try block's exception is lost, but in reality both are captured via suppressed exceptions.
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
✓
Both the try block and the close method threw exceptions.
The output shows both a primary exception from the try block and a suppressed exception from the close method. In try-with-resources, if both the try block and the close method throw exceptions, the primary exception from the try block is propagated, and the close method's exception is added as a suppressed exception. The output displays both exceptions, confirming that both occurred.
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 try block threw an exception, but the resource closed successfully.
Why it's wrong here
Close also threw an exception (suppressed).
- ✗
Only the close method threw an exception, and the try block did not throw.
Why it's wrong here
Primary exception from main indicates try threw.
- ✓
Both the try block and the close method threw exceptions.
Why this is correct
Both exceptions present; close exception is suppressed.
- ✗
The close method threw an exception, and the try block completed normally.
Why it's wrong here
