. Write a well documented (commented) program, "Point", which implements a Point data type with the following constructor: [MO4.2, MO4.3] Point(double x, double y, double z) and, the following API: double distanceto(Point q) it returns the Euclidean distance between this and q. The Euclidean distance between (x1, y1, z1) and (x2, y2, z2) is defined as sqrt( (x1-x2)^2 + (y1-y2)^2) + (z1-z2)^2). String toString() it returns the string representation of the point. An example would be (2.3,4.5,3.0). Write a main method in the class that is used to test it. It should create two Point objects using input provided by the user on the command-line. Then it should print out the two points followed by their Euclidean distance A sample run would be as follows.

>java Point 2.1 3.0 3.5 4 5.2 3.5

The first point is (2.1,3.0,3.5)

The second point is (4.0,5.2,3.5)

Their Euclidean distance is 2.91
