1Z0-829 Controlling Program Flow Practice Question

⚠ Common exam trap
It's easy for candidates to confuse the execution guarantees of while (zero or more times) versus do-while (at least once), leading them to incorrectly select B or D as true.
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 break statement can be used to exit a loop prematurely.
The break statement in Java is used to immediately terminate the execution of a loop (for, while, or do-while) and transfer control to the statement following the loop. This allows premature exit based on a condition, which is a fundamental control flow mechanism in Java.
