Pair Of Two Numbers - Return Average / Distance / Maximum And Minimum Value

I have been having difficulty with the weeks concepts in my online Java class, the program is to be as followed:

For this exercise you will implement a class called Pair, that represents a pair of two numbers.The Pair class should include the following constructor and methods:

CONSTRUCTORS
public Pair(double num1, double num2) -- Creates an object that represents a pair of double values

METHODS

public double getAverage() -- Returns the average value of the two numbers
public double getDistance() -- Returns the absolute vale of the distance between the two numbers
public double getMaximum() -- Returns the maximum value of the two numbers
public double getMinimum() -- Returns the minimum vale of the two numbers

Write a class called PairTest that tests your Pair implementation. The PairTest should prompt the user for the two values, create a Pair object with the values and then print the average, distance, maximum, and minimum of the pair. The input / output should look like the following:

Enter the first number: 5.5
Enter the second number: 3.0

Average: 4.25
Distance: 2.5
Maximum: 5.5
Minimum: 3.0

NOTE: For this exercise, your solution should not use any conditional statements. Instead you should use the methods provided by thejava.util.Math.

So far I have:

import java.lang.Math;
import java.util.Scanner;
public class Main
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
{
System.out.println("Please enter a value for the first number");
