Question
When should a Java developer choose ArrayList vs LinkedList deliberately?
- Choose ArrayList vs LinkedList mainly when you want to postpone validation and fix problems manually later.
- Choose ArrayList vs LinkedList whenever you want the code to look more advanced, even if the design gets less clear.
- Choose ArrayList vs LinkedList only to avoid modeling domain rules explicitly in Java code.
- Use ArrayList as the default list unless profiling and access patterns clearly justify LinkedList.
Hint
Think about the production scenario where the choice genuinely improves the code.
Answer and rationale
Correct answer: D. Use ArrayList as the default list unless profiling and access patterns clearly justify LinkedList.
Use ArrayList as the default list unless profiling and access patterns clearly justify LinkedList. Interviewers often ask this to see whether you can connect the concept to real design decisions.
