public class TestGraphic {
	
	
	
	private static PrintWriter  stdErr =
		new  PrintWriter(System.err, true);

	/**

	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Line line1 = new Line();
		Line line2 = new Line(new Point(1,1),new Point(3,5),"black");
		stdErr.println("Test method in Class Line");
		line1.draw();
		line1.rotate();
		line2.draw();
		line2.rotate();
		
		
		Circle circle1 = new Circle();
		Circle circle2 = new Circle("blcak","red",new Point(2,4),3);
		
		stdErr.println("Test method in Class Circle");
		circle1.draw();
		circle1.rotate();
		circle2.draw();
		circle2.rotate();
		
		GraphicObject[] graphic = {line1,line2,circle1,circle2};
		
		stdErr.println("test the polymorship");
		
		for(GraphicObject object : graphic){
			object.draw();
			object.rotate();
		}
