New to Java

Hi,

I have two points (I am drawing 2 circles) and have to measure the angle between these 2 points - they are connected with a line.

I know that I have to do something like

Math.toDegrees(Math.atan2(x,y))

but I don't know how to exactly implement it.


I thought about doing something like the following:

boolean angleGreaterThan45(Line2D lineBetweenPoints, Point2D pointCenter) {
  return pointCenter.Math.toDegrees ( Math.atan2 ( lineBetweenPoints.x, lineBetweenPoints.y ) ) );
}

However this doesn't work...

The 2 points are coded like this:

public Point createStartPoint() {
  Random rand = new Random();
  startX = rand.nextInt(maxStartX + 1);
  startY = rand.nextInt(maxStartY + 1);
  return new Point(startX, startY);
}

...and the line between the 2 points like this:

Line2D.Double lineBetweenPoints, = new Line2D.Double(startPoint, endPoint);

Thanks a lot for your help!
