Answer
Use '.equals()' for consistent wrapper comparison.
Wrappers require '.equals()' to compare values reliably, as '==' may give false negatives due to object identity checks. This is crucial for consistency in logic, especially in collections. 'Integer a = 1000; Integer b = 1000; a.equals(b)' ensures true.
