PenPoint

public abstract class Point
extends java.lang.Object
implements java.lang.Comparable

Abstract class for a point- a single point created by the pen. Outlines methods a point should have to set/read: X coordinate Y coordinate Pressure (the amount of pressure applied for that point) Time stamp Label
