淡入淡出
以下是在 JavaFX 中演示淡入淡出过渡的程序。将此代码保存在名称为的文件中FadeTransitionExample.java.import javafx.animation.FadeTransition; import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.Circle; import javafx.stage.Stage; import javafx.util.Duration; public class FadeTransitionExample extends Application { @Override public void start(Stage stage) { //Drawing a Circle Circle circle = new Circle(); //Setting the position of the circle circle.setCenterX(300.0f); circle.setCenterY(135.0f); //Setting the radius of the circle circle.setRadius(100.0f); //Setting the color of the circle circle.setFill(Color.BROWN); //Setting the stroke width of the circle circle.setStrokeWidth(20); //Creating the fade Transition FadeTransition fadeTransition = new FadeTransition(Duration.millis(1000)); //Setting the node for Transition fadeTransition.setNode(circle); //Setting the property fromValue of the transition (opacity) fadeTransition.setFromValue(1.0); //Setting the property toValue of the transition (opacity) fadeTransition.setToValue(0.3); //Setting the cycle count for the transition fadeTransition.setCycleCount(50); //Setting auto reverse value to false fadeTransition.setAutoReverse(false); //Playing the animation fadeTransition.play(); //Creating a Group object Group root = new Group(circle); //Creating a scene object Scene scene = new Scene(root, 600, 300); //Setting title to the Stage stage.setTitle("Fade transition example"); //Adding scene to the stage stage.setScene(scene); //Displaying the contents of the stage stage.show(); } public static void main(String args[]){ launch(args); } }使用以下命令从命令提示符编译并执行保存的 java 文件。javac FadeTransitionExample.java java FadeTransitionExample执行时，上述程序会生成一个 JavaFX 窗口，如下所示。

填充过渡
以下是在 JavaFX 中演示填充转换的程序。将此代码保存在名称为的文件中FillTransitionExample.java.import javafx.animation.FillTransition; import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.Circle; import javafx.stage.Stage; import javafx.util.Duration; public class FillTransitionExample extends Application { @Override public void start(Stage stage) { //Drawing a Circle Circle circle = new Circle(); //Setting the position of the circle circle.setCenterX(300.0f); circle.setCenterY(135.0f); //Setting the radius of the circle circle.setRadius(100.0f); //Setting the color of the circle circle.setFill(Color.BROWN); //Setting the stroke width of the circle circle.setStrokeWidth(20); //Creating the fill Transition FillTransition fillTransition = new FillTransition(Duration.millis(1000)); //Setting the shape for Transition fillTransition.setShape(circle); //Setting the from value of the transition (color) fillTransition.setFromValue(Color.BLUEVIOLET); //Setting the toValue of the transition (color) fillTransition.setToValue(Color.CORAL); //Setting the cycle count for the transition fillTransition.setCycleCount(50); //Setting auto reverse value to false fillTransition.setAutoReverse(false); //Playing the animation fillTransition.play(); //Creating a Group object Group root = new Group(circle); //Creating a scene object Scene scene = new Scene(root, 600, 300); //Setting title to the Stage stage.setTitle("Fill transition example"); //Adding scene to the stage stage.setScene(scene); //Displaying the contents of the stage stage.show(); } public static void main(String args[]){ launch(args); } }使用以下命令从命令提示符编译并执行保存的 java 文件。javac FillTransitionExample.java java FillTransitionExample执行时，上述程序会生成一个 JavaFX 窗口，如下所示。

笔画过渡
以下是在 JavaFX 中演示 Stoke Transition 的程序。将此代码保存在名称为的文件中StrokeTransitionExample.java.import javafx.animation.StrokeTransition; import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.Circle; import javafx.stage.Stage; import javafx.util.Duration; public class StrokeTransitionExample extends Application { @Override public void start(Stage stage) { //Drawing a Circle Circle circle = new Circle(); //Setting the position of the circle circle.setCenterX(300.0f); circle.setCenterY(135.0f); //Setting the radius of the circle circle.setRadius(100.0f); //Setting the color of the circle circle.setFill(Color.BROWN); //Setting the stroke width of the circle circle.setStrokeWidth(20); //creating stroke transition StrokeTransition strokeTransition = new StrokeTransition(); //Setting the duration of the transition strokeTransition.setDuration(Duration.millis(1000)); //Setting the shape for the transition strokeTransition.setShape(circle); //Setting the fromValue property of the transition (color) strokeTransition.setFromValue(Color.BLACK); //Setting the toValue property of the transition (color) strokeTransition.setToValue(Color.BROWN); //Setting the cycle count for the transition strokeTransition.setCycleCount(50); //Setting auto reverse value to false strokeTransition.setAutoReverse(false); //Playing the animation strokeTransition.play(); //Creating a Group object Group root = new Group(circle); //Creating a scene object Scene scene = new Scene(root, 600, 300); //Setting title to the Stage stage.setTitle("Stroke transition example"); //Adding scene to the stage stage.setScene(scene); //Displaying the contents of the stage stage.show(); } public static void main(String args[]){ launch(args); } }使用以下命令从命令提示符编译并执行保存的 java 文件。javac StrokeTransitionExample.java java StrokeTransitionExample执行时，上述程序会生成一个 JavaFX 窗口，如下所示。
