/* Private fields (intResult and doubleResult) are used for encapsulation.
The constructor initializes both results to 0 and 0.0.
There are overloaded add methods to handle both integer and double addition.
Getter methods (getIntResult and getDoubleResult) correctly return the values of intResult and doubleResult */
