LLMAnswer with sources
Simple meaning
== may compare references
WHY — Java instead of guessing?
Why interviewers care about Java:
They want a clean
contrast on Java, not two memorised paragraphs.
Say what changes for
the developer, then one case where picking wrong hurts.
Stay structured
Name the idea, why it exists, then one short example.
Close cleanly
End with when you use it and one common pitfall.

Before you speak the answer, walk the interviewer through these steps:
- 1Define it

- 2Why it exists
equals compares values.
- 3How it works

- 4I use equals for
object equality.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.
EXAMPLE — See it in action
