Thread: Line2D implementation

Hey guys I got this assignment for my java class, to create two classes Point2D and Line2D.

Now I've created the Point2D class and it just takes in x,y coordinates and creates a point. It has a few methods, getX, getY and distanceTo(point b)

What I need to do now is create a Line2D class which also should have a few methods, but I'm stuck at implementing the constructor which should take two point2D variables and create a line between point a and point b.

So basically the constructor should look like this:

public Line2D(Point2D a, Point2D b)
{
....
}

I'm having real trouble getting my head around what should be inside the brackets, so I'm kinda stuck at the moment. Any pointers/help would be greatly appreciated.

Well, this is a constructor method, which is used to initialize class variables. Like;

private Point2D a;
private Point2D b;
 
public Line2D(Point2D a, Point2D b)
{
     this.a = a; // This will set passed parameter to class variable a 
     this.b = b; // ^ same
}
 
public double getDistance(){
    // Calculate distance and return it
}
