Class Point

java.lang.Object

edu.duke.Point

public class Point
extends Object

The Point class represents a two-dimensional location, constructed from (x,y) coordinates with some methods for access and the capability to calculate the distance from this point to another point.

Example usage:

 Point a = new Point(3, 4);
 Point b = new Point(2, 5);
 double dist = a.distance(b);
