Quick Answer
For objects: == checks if two references point to the same memory location (same object instance). equals() checks logical equality based on the implementation. By default, equals() uses == (reference equality). Override equals() to define meaningful equality (e.g., two Users are equal if they have the same userId). Always override hashCode() when you override equals().
