Question 488 of 481
1Z0-811 What is Java Practice Question
A developer is writing a Java application that processes a large number of transactions. The application must ensure that each transaction is committed only if all steps complete successfully, otherwise the entire transaction should be rolled back. Which Java concept should the developer use to implement this requirement?
⚠ Common exam trap
Oracle often tests whether candidates confuse 'transaction management' with 'multithreading' — the trap here is assuming that concurrent execution (Option C) is needed for atomicity, when in fact atomicity is enforced by exception handling and explicit commit/rollback calls, not by running steps in parallel.

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
✓
Exception handling
Exception handling in Java allows the developer to catch runtime failures (e.g., SQLException, IOException) within a try block and, in the catch block, invoke a rollback on the transaction (e.g., Connection.rollback()). If all steps succeed, the transaction is committed via Connection.commit(). This ensures atomicity — the 'all-or-nothing' property required for transaction processing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Exception handling
Why this is correct
Exception handling can catch failures and trigger rollback.
- ✗
Inheritance
Why it's wrong here
Inheritance is for code reuse, not transaction management.
- ✗
Multithreading
Why it's wrong here
Multithreading handles concurrent execution, not transactional integrity.
- ✗
Encapsulation
Why it's wrong here
Encapsulation hides data, not manage transactions.
