Question

Which statement about equals() vs == is the strongest interview answer?

  1. equals() vs == is mostly a naming style choice and has little effect on runtime or design.
  2. equals() vs == exists mainly to reduce the number of Java files in a project.
  3. equals() vs == matters only for frontend frameworks, not for core Java applications.
  4. == checks reference identity for objects, while equals checks logical value when implemented correctly.

Hint

Start with the core rule behind equals() vs ==.

Answer and rationale

Correct answer: D. == checks reference identity for objects, while equals checks logical value when implemented correctly.

== checks reference identity for objects, while equals checks logical value when implemented correctly. This is the base concept interviewers commonly test first.
