1Z0-829 Handling Exceptions Practice Question

Which TWO statements about the try-with-resources statement are correct? (Choose two.)

⚠ Common exam trap

Many candidates think resources must be declared with the final keyword (Option B) or that finally blocks are prohibited (Option D), but the exam tests the exact JLS rules: resources are effectively final, and finally blocks are allowed but execute after resource closure.

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

✓

The resource class must implement AutoCloseable.

The try-with-resources statement requires that each resource implements the AutoCloseable interface (or its subinterface Closeable). This interface defines the close() method, which is automatically invoked by the JVM when the try block completes, ensuring proper resource management without explicit finally blocks.
