Note that you have added the
getX()
,
getY()
,
setX()
, and
setY()
methods to the class to make the
private
data members accessible.
The
Line
class also needs to be amended to make the methods public and to declare the class as public.
You have to change its
intersects()
method so that it can access the private data members of
Point
objects using the
set...()
and
get...()
methods in the
Point
class. The code in
Line.java
, with
changes highlighted, is:
package Geometry;
public class Line {
// Create a line from two points
public Line(final Point start, final Point end) {
this.start = new Point(start);
this.end = new Point(end);
}
// Create
a line from two coordinate pairs
public Line(double xStart, double yStart, double xEnd, double yEnd)
{
