解析几何点和直线的关系
Point2D p1 = new Point2D.Double(10,20);
Point2D p2 = new Point2D.Double(100,200);
Rectangle2D rect = new Line2D.Double(p1, p2).getBounds2D();
//一般式直线方程
Double A = p2.getY() - p1.getY();
Double B = p1.getX() - p2.getX();
Double C = p2.getX() * p1.getY() - p1.getX() * p2.getY();
System.out.println(String.format("A=%s, B=%s, C=%s", A, B, C));
