Question
When should a Java developer choose Two-Dimensional Arrays deliberately?
- Choose Two-Dimensional Arrays mainly when you want to postpone validation and fix problems manually later.
- Choose Two-Dimensional Arrays whenever you want the code to look more advanced, even if the design gets less clear.
- Choose Two-Dimensional Arrays only to avoid modeling domain rules explicitly in Java code.
- Use two-dimensional arrays for grids, dynamic-programming tables, and matrix-style interview problems with known bounds.
Hint
Think about the production scenario where the choice genuinely improves the code.
Answer and rationale
Correct answer: D. Use two-dimensional arrays for grids, dynamic-programming tables, and matrix-style interview problems with known bounds.
Use two-dimensional arrays for grids, dynamic-programming tables, and matrix-style interview problems with known bounds. Interviewers often ask this to see whether you can connect the concept to real design decisions.
