Question

What deeper point about Polymorphism, Overloading, and Overriding should a senior Java developer mention?

  1. At senior level, the right answer is that Polymorphism, Overloading, and Overriding exists mostly for historical syntax reasons.
  2. At senior level, the JVM removes the tradeoffs around Polymorphism, Overloading, and Overriding, so design choices barely matter.
  3. Real polymorphism depends on substitutability and contract preservation, not just on matching method names.
  4. At senior level, any approach to Polymorphism, Overloading, and Overriding 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: C. Real polymorphism depends on substitutability and contract preservation, not just on matching method names.

Real polymorphism depends on substitutability and contract preservation, not just on matching method names. This is the kind of tradeoff-aware answer senior interviews usually expect.
