The Pair2 class (so called to distinguish it from an earlier assignment) takes two values as parameters in the constructor. The following methods are used to calculate and return results:
sum() = the sum of the two valuesdifference() = the difference between the two values (n1 - n2)product() = the product of the two valuesaverage() = the averagedistance() = the distance (absolute value of the difference)max() = the maximum (the larger of the two)min() = the minimum (the smaller of the two)Then write a test program Pair2Tester.java with a main() method that demonstrates the use of the Pair2 class.
