Learning Profile for Assignment #1, And Question #3

Name: Mo Khan
Student ID: 3431709

1. Problem Statement:

Write a program that prompts the user to enter two points `(x1, y1)` and `(x2, y2)`.
Calculate and display the distance between the two points using the formula below.
Round the answer up to 2 decimal points.
You can use `Math.pow(a,0.5)` to compute the square root of an expression.
`Math.pow()` returns a double.

For example, the distance between the points (−2, −3) and (−4, 4) is approximately 7.28, as shown below.

2. Description of the Code: 

[Briefly describe how you solved the problem in your code. You should include short description of classes, methods, and variables (if necessary) that you used in your code.]

I took the example described in the problem statement and converted it
to a junit test. Then I implemented the `calculateDistance` interface.

3. Errors and Warnings:
