Design and implement a Point class which models points in the Cartesian coordinate system.

Design and implement a Line class using the idea that 2 points determine a line.

Be sure to include the following methods: 1. A constructor with defaults. 2. Get and Set methods. 3. Appropriate useful methods.

Write a main driver program (no user input) that demonstrates the usage of your class designs.
