• Aim: Write a program that displays the color of a circle as red when the mouse button is pressed and as blue when the mouse button is released.
• Code:

  import javafx.application.Application;
  import javafx.scene.Scene;
  import javafx.scene.layout.StackPane;
  import javafx.scene.paint.Color;
  import javafx.scene.shape.Circle;
  import javafx.stage.Stage;
  public class practical19 extends Application {
      @Override
      public void start(Stage primaryStage) {
          double width = 250;
          double height = 250;
          Circle c = new Circle(width / 2, height / 2, Math.min(width, height) / 10,
                  Color.BLUE);
          c.setStroke(Color.WHITE);
          StackPane pane = new StackPane(c);
          primaryStage.setScene(new Scene(pane, width, height));
          pane.setOnMousePressed(e -> c.setFill(Color.RED));
          pane.setOnMouseReleased(e -> c.setFill(Color.BLUE));
          primaryStage.setTitle("Practical19");
          primaryStage.show();
      }
  
      public static void main(String[] args) {
          Application.launch(args);
      }
  }
