Question

What deeper point about Garbage Collection should a senior Java developer mention?

  1. GC tuning is fundamentally about balancing throughput, pause time, allocation rate, and object lifetime patterns.
  2. At senior level, the right answer is that Garbage Collection exists mostly for historical syntax reasons.
  3. At senior level, the JVM removes the tradeoffs around Garbage Collection, so design choices barely matter.
  4. At senior level, any approach to Garbage Collection is equally correct if it compiles and passes a small test.

Hint

Look beyond syntax and explain the runtime, API, or design consequence.

Answer and rationale

Correct answer: A. GC tuning is fundamentally about balancing throughput, pause time, allocation rate, and object lifetime patterns.

GC tuning is fundamentally about balancing throughput, pause time, allocation rate, and object lifetime patterns. This is the kind of tradeoff-aware answer senior interviews usually expect.
