JavaFX Line

In general, Line can be defined as the geometrical structure which joins two points (X1,Y1) and (X2,Y2) in a X-Y coordinate plane. JavaFX allows the developers to create the line on the GUI of a JavaFX application. JavaFX library provides the class Line which is the part of javafx.scene.shape package.

How to create a Line?

Follow the following instructions to create a Line.

Instantiate the class javafx.scene.shape.Line.
set the required properties of the class object.
Add class object to the group

Properties

Line class contains various properties described below.

Property	Description	Setter Methods
endX	The X coordinate of the end point of the line	setEndX(Double)
endY	The y coordinate of the end point of the line	setEndY(Double)
startX	The x coordinate of the starting point of the line	setStartX(Double)
startY	The y coordinate of the starting point of the line	setStartY(Double)

Example 1:

  package application;  import javafx.application.Application;  import javafx.scene.Scene;  import javafx.scene.Group;  import javafx.scene.shape.Line;  import javafx.stage.Stage;  public class LineDrawingExamples extends Application{    @Override  public void start(Stage primaryStage) throws Exception {  // TODO Auto-generated method stub  Line line = new Line(); //instantiating Line class   line.setStartX(0); //setting starting X point of Line  line.setStartY(0); //setting starting Y point of Line   line.setEndX(100); //setting ending X point of Line   line.setEndY(200); //setting ending Y point of Line   Group root = new Group(); //Creating a Group  root.getChildren().add(line); //adding the class object //to the group  Scene scene = new Scene(root,300,300);  primaryStage.setScene(scene);  primaryStage.setTitle(“Line Example”);  primaryStage.show();    }  public static void main(String[] args) {  launch(args);  }    }  

Output:

JavaFX Line Output 1

Example 2 : Creating Multiple Lines

  package application;  import javafx.application.Application;  import javafx.scene.Group;  import javafx.scene.Scene;  import javafx.scene.paint.Color;  import javafx.scene.shape.Line;  import javafx.stage.Stage;  public class LineDrawingExamples extends Application{  public static void main(String[] args) {  launch(args);  }  @Override  public void start(Stage primaryStage) throws Exception {  // TODO Auto-generated method stub  primaryStage.setTitle(“Line Drawing Examples”);  Line line1 = new Line(10,50,150,50); //Line(startX,startY,endX,endY)  Line line2 = new Line(10,100,150,100);  Line line3 = new Line(10,50,10,100);  Line line4 = new Line(150,50,150,100);  Group root = new Group();  root.getChildren().addAll(line1,line2,line3,line4);  Scene scene = new Scene (root,300,200,Color.GREEN);  primaryStage.setScene(scene);  primaryStage.show();  }    }  

Output:

JavaFX Line Output 2
