Explain the Stroke property of 2D shapes in JavaFX

JavaObject Oriented ProgrammingProgramming

The stroke property specifies/defines the color of the boundary of a shape. You can set the color of the boundary using the setStroke() method of the javafx.scene.shape.Shape class.

This method accepts a Color value as a parameter and sets the given color to the boundary of a shape.

By default, the value of this property for the shapes (objects) line, path and polyline is null and, for all the remaining shapes the default value of this property is Color.BLACK.

Example

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.shape.Line;
import javafx.scene.shape.Polygon;
import javafx.scene.text.Font;
import javafx.scene.text.FontPosture;
import javafx.scene.text.FontWeight;
import javafx.scene.text.Text;
import javafx.stage.Stage;
public class StrokeExample extends Application {
   public void start(Stage stage) {
      Font font = Font.font("verdana", FontWeight.BOLD, FontPosture.REGULAR, 12);
      Text label1 = new Text("Original Image");
      label1.setFont(font);
      label1.setX(250.0);
      label1.setY(125.0);
      Polygon rhombus1 = new Polygon(300.0, 0.0, 250.0, 50.0, 300.0, 100.0, 350.0, 50.0);
      Text label2 = new Text("Stroke for a line");
      label2.setFont(font);
      label2.setX(50.0);
      label2.setY(275.0);
      //Constructing a line
      Line line = new Line();
      line.setStartX(50.0);
      line.setStartY(200.0);
      line.setEndX(150.0);
      line.setEndY(200.0);
      line.setStrokeWidth(10.0);
      line.setStroke(Color.DARKBLUE);
      Text label3 = new Text("Stroke: Blue");
      label3.setFont(font);
      label3.setX(250.0);
      label3.setY(275.0);
      Polygon rhombus3 = new Polygon(300.0, 150.0, 250.0, 200.0, 300.0, 250.0, 350.0, 200.0);
      rhombus3.setStroke(Color.BLUE);
      rhombus3.setStrokeWidth(7.0);
      Text label4 = new Text("Stroke: Red");
      label4.setFont(font);
      label4.setX(450.0);
      label4.setY(275.0);
      Polygon rhombus4 = new Polygon(490.0, 150.0, 440, 200.0, 490.0, 250.0, 540.0, 200.0);
      rhombus4.setStroke(Color.RED);
      rhombus4.setStrokeWidth(7.0);
      //Creating a Group object
      Group root = new Group(label1, label2, label3, label4, rhombus1, line, rhombus3, rhombus4);
      //Creating a scene object
      Scene scene = new Scene(root, 595, 310);
      //Setting title to the Stage
      stage.setTitle("Stroke 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);
   }
}
