**直线类Line  
矩形类Rectangle  
圆类 Circle  
椭圆类Ellipse  
弧类 Arc  
多边形类Polygon  
折线类Polyline**

Line line = new Line(0,0,150,150);
            borderPane.getChildren().add(line);

**交互式系统设计**  
鼠标拖动绘图的基本思想是用很多短直线一次相连代替直线

**动画程序设计**  
淡入淡出动画  
FadeTransition()

package sample;
    
    import javafx.animation.Animation;
    import javafx.animation.FadeTransition;
    import javafx.application.Application;
    import javafx.geometry.Orientation;
    import javafx.scene.Scene;
    import javafx.scene.control.CheckMenuItem;
    import javafx.scene.control.Menu;
    import javafx.scene.control.MenuBar;
    import javafx.scene.control.Slider;
    import javafx.scene.layout.BorderPane;
    import javafx.scene.paint.Color;
    import javafx.scene.shape.Circle;
    import javafx.scene.shape.Line;
    import javafx.stage.Stage;
    import javafx.scene.input.MouseEvent;
    import javafx.util.Duration;
    
    
    public class Main extends Application {
        
    
    
        @Override
        public void start(Stage primaryStage) throws Exception{
        
            BorderPane borderPane = new BorderPane();
            Circle circle = new Circle(150,150,100);
            circle.setFill(Color.BLACK);
            FadeTransition ft = new FadeTransition(Duration.millis(2000));
            ft.setCycleCount(Animation.INDEFINITE);
            ft.setFromValue(1.0);
            ft.setToValue(0.0);
            ft.setAutoReverse(true);
            ft.setNode(circle);
            ft.play();
            borderPane.setCenter(circle);
    
            primaryStage.setScene(new Scene(borderPane,300,300));
            primaryStage.show();
    
    
        }
    
    
        public static void main(String[] args) {
        
            launch(args);
        }
    }

**移动效果**  
Pathtransition()

**时间轴动画**  
太多了懒得写了
