JavaFX | LineTo class - GeeksforGeeks

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:

LineTo(): Creates a new LineTo object.
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:

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.

// add LineTo object to it and display it

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:

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.
