- explanation: "Integer caching applies to values -128 to 127. dadAge and momAge both reference the same cached Integer object for 127, so == returns true. sonAge and daughterAge are different objects for 128 (outside cache range), so == returns false. However, equals() compares values, not references, so both equals() calls return true regardless of caching."
