Java

Write a program that prompts the user for two numbers then points.
The sum
The difference
The product
the average
the distance (absolute value of the difference)
the maximum (the larger of the two)
the minimum (the smaller of the two)

To do so
implement a class
public class fair
{
Constructs a pair.
@param aFirst the first value of the pair.
@param Asecond the second value of the pair.

public Pair(double aFirst, double aSecond){. . .}
/**
Computes the sum of the values of this pair.
@return the sum of the first and second values
*/ public double getSum() {. . .}
...
}

INSTRUCTIONS
The PairTest.java program should use bullet proof input to prompt and collect the two values for the number pair from the user, create a number pair object using these values, display the initial values and should output the computed 7 listed computed values .

Extra Credit option:
include additional code in the driver (PairTest) that creates a pair with two random double values between 0 and 10 inclusive. Be sure to show the two pair values as well as the computed values. (In other words, the user should be able to confirm that the program is correct using the Random numbers by inspecting the output.)
