Explain the Stroke Line Cap property of 2D shapes in JavaFX

The Stroke Line Cap specifies/defines the end cap style of the line. You can set the Stroke Line Cap value using the setStrokeLineCap() method of the javafx.scene.shape.Shape class.

Java FX supports three kinds of stroke line caps represented by three constants of the Enum named StrokeLineCap they are −

• BUTT − This type ends the unclosed subpaths without any decoration.

• ROUND − This type ends the unclosed paths with a round projection.

• SQUARE − This type ends the unclosed paths with a square projection.

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.StrokeLineCap;
import javafx.scene.shape.StrokeType;
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 StrokeLineCapExample extends Application {
   public void start(Stage stage) {
      Font font = Font.font("verdana", FontWeight.BOLD, FontPosture.REGULAR, 12);
      Text label1 = new Text("Normal Line");
      label1.setFont(font);
      label1.setX(260.0);
      label1.setY(90.0);
      Line line1 = new Line(250.0, 50.0, 350.0, 50.0);
      Text label2 = new Text("Line Cap: BUTT");
      label2.setFont(font);
      label2.setX(50.0);
      label2.setY(235.0);
      Line line2 = new Line(50.0, 200.0, 150.0, 200.0);
      line2.setStroke(Color.DARKBLUE);
      line2.setStrokeWidth(10.0);
      line2.setStrokeType(StrokeType.CENTERED);
      line2.setStrokeLineCap(StrokeLineCap.BUTT);
      Text label3 = new Text("Line Cap: SQUARE");
      label3.setFont(font);
      label3.setX(245.0);
      label3.setY(235.0);
      Line line3 = new Line(250.0, 200.0, 350.0, 200.0);
      line3.setStrokeWidth(10.0);
      line3.setStroke(Color.DARKBLUE);
      line3.setStrokeLineCap(StrokeLineCap.SQUARE);
      Text label4 = new Text("Line Cap: ROUND");
      label4.setFont(font);
      label4.setX(440.0);
      label4.setY(235.0);
      Line line4 = new Line(440, 200.0, 540.0, 200.0);
      line4.setStrokeWidth(10.0);
      line4.setStroke(Color.DARKBLUE);
      line4.setStrokeLineCap(StrokeLineCap.ROUND);
      //Creating a Group object
      Group root = new Group(label1, label2, label3, label4, line1, line2, line3, line4);
      //Creating a scene object
      Scene scene = new Scene(root, 595, 310);
      //Setting title to the Stage
      stage.setTitle("Stroke Line Cap 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);
   }
}
