Question

When should a Java developer choose Java Memory Model, volatile, and synchronized deliberately?

  1. Choose Java Memory Model, volatile, and synchronized mainly when you want to postpone validation and fix problems manually later.
  2. Choose Java Memory Model, volatile, and synchronized whenever you want the code to look more advanced, even if the design gets less clear.
  3. Choose Java Memory Model, volatile, and synchronized only to avoid modeling domain rules explicitly in Java code.
  4. Use synchronized or higher-level concurrency tools when multiple related operations must stay atomic and consistent.

Hint

Think about the production scenario where the choice genuinely improves the code.

Answer and rationale

Correct answer: D. Use synchronized or higher-level concurrency tools when multiple related operations must stay atomic and consistent.

Use synchronized or higher-level concurrency tools when multiple related operations must stay atomic and consistent. Interviewers often ask this to see whether you can connect the concept to real design decisions.
