JavaFX | LineTo class

LineTo class is a part of JavaFX. LineTo class draws a line from the current position to specified x and y coordinate. LineTo class inherits PathElement class.

Constructor of the class:

1. LineTo(): Creates a new LineTo object.
2. LineTo(double x, double y): Creates a new LineTo object with specified x, y coordinates.

Commonly Used Methods:

Method	Explanation
getX()	Returns the value of X coordinate.
getY()	Returns the value of Y coordinate.
setX(double v)	Sets the value of X coordinate.
setY(double v)	Sets the value of Y coordinate.
xProperty()	Defines the X coordinate.
yProperty()	Defines the Y coordinate.

Below programs illustrate the use of LineTo Class:

1. Java program to create a path and add LineTo object to it and display it:
   • In this program, we will create a Path object named path.
   • Create an HLineTo object with specified X and Y coordinate.
   • Then create a MoveTo object named moveto.
   • Now add the MoveTo and Lineto object to the path.
   • Add this path to Group object and add the group object to the scene and add the scene to the stage and call the show() function to display the final results.

   // Java program to create a path and
   // add LineTo object to it and display it

   import javafx.scene.Scene;
   import javafx.scene.control.*;
   import javafx.scene.layout.*;

   public class LineTo_1 extends Application {
   
       // launch the application
       public void start(Stage stage)
       {
   
           try {
   
               // set title for the stage
               stage.setTitle("LineTo");
   
               // create LineTo
               LineTo Lineto = new LineTo(200, 200);
   
               // create moveto
               MoveTo moveto = new MoveTo(100, 100);
   
               // create a Path
               Path path = new Path(moveto, Lineto);
   
               // set fill for path
               path.setFill(Color.BLACK);
   
               // set stroke width
               path.setStrokeWidth(2);
   
               // create a Group
               Group group = new Group(path);
   
               // create a scene
               Scene scene = new Scene(group, 400, 300);
   
               // set the scene
               stage.setScene(scene);
   
               stage.show();
           }
   
           catch (Exception e) {
   
               System.out.println(e.getMessage());
           }
       }
   
       // Main Method
       public static void main(String args[])
       {
   
           // launch the application
           launch(args);
       }
   }

   Output:

   

2. Java program to create a path and add multiple LineTo objects to it and display it:
   • In this program, we will create a Path object named path.
   • Create four LineTo object with specified X and Y coordinates names Lineto, Lineto1, Lineto2, Lineto3.
   • Then create a MoveTo object named moveto.
   • Now add the MoveTo and Lineto objects to the path.
   • Add this path to Group object and add the group object to the scene and add the scene to the stage and call the show() function to display the final results.
