Question
When should a Java developer choose PriorityQueue and Heap Basics deliberately?
- Choose PriorityQueue and Heap Basics mainly when you want to postpone validation and fix problems manually later.
- Choose PriorityQueue and Heap Basics whenever you want the code to look more advanced, even if the design gets less clear.
- Use PriorityQueue for top-k selection, shortest-path frontiers, and any workflow that repeatedly removes the next best candidate.
- Choose PriorityQueue and Heap Basics only to avoid modeling domain rules explicitly in Java code.
Hint
Think about the production scenario where the choice genuinely improves the code.
Answer and rationale
Correct answer: C. Use PriorityQueue for top-k selection, shortest-path frontiers, and any workflow that repeatedly removes the next best candidate.
Use PriorityQueue for top-k selection, shortest-path frontiers, and any workflow that repeatedly removes the next best candidate. Interviewers often ask this to see whether you can connect the concept to real design decisions.
