  +--Point

public class Point

extends java.lang.Object

A representation of a point in N-dimensional space. In the current implementation N == 3.

Constructor Summary

Point(int x, int y, int z)
Create a point in 3 dimensional space given three integers Requires: MAX_DIM == 3

Point(java.lang.String s)
Create a new point given a string with MAX_DIM integers on it

Method Summary

double	distanceFrom(Point p) Calculate the distance of this point from point p Requires: p must not be null.
double	get(int i) Return the value in the ith dimension of this point Requires: 0 <= i < MAX_DIM
boolean	sameDimension(Point p, int k) Returns true if this point has the same value in dimension k as point p.
java.lang.String	toString() Construct the string representation of a Point: a list of the values in for each dimension.
