 class Point {
	private double x;
	private double y;
	
	Point(){
		x = y =0.0;
	}
	
	Point(double x,double y){
		this.x = x;
		this.y = y;
	}
	
	public Point getPoint(){
		return new Point(x,y);
		
	}
	public double getX(){
		return x;
	}
	
	public double getY(){
		return y;
	}
	public void setNewPoint(double newX,double newY){
		x = newX;
		y = newY;
	}

}
