In JavaFX, you can draw three kinds of arc’s namely −
You may set the type of the arc the usage of the technique setType() by passing any of the following properties − ArcType.OPEN, ArcType.CHORD, ArcType.round.
To draw an arc in JavaFX, follow the steps given below.
Create a Java class and inherit the application class of the package javafx.application and implement the start() method of this class as follows.
You may create an arc in JavaFX by means of instantiating the class named Arc which belongs to a package javafx.scene.shape. you can instantiate this class as proven below.
Specify the x, y coordinates of the center of the Ellipse (of which this arc is part of). those coordinates consist of – radiusX, radiusY, start angle and length of the arc using their respective setter methods as proven in the following code block.
You may also set the type of the arc (round, chord open) through the usage of the setType() method.
You can set the type of the arc using the method setType() as shown in the following code block.
In the start() technique create a group object by using instantiating the class named group, which belongs to the package javafx.scene.
Pass the Arc (node) item created inside the previous step as a parameter to the constructor of the group class. This have to be done if you want to upload it to the group as shown below –
Create a Scene through instantiating the class named Scene which belongs to the package javafx.scene. To this class pass the institution object (root) created within the preceding step.
Similarly to the root item, you may also pass double parameters representing height and width of the screen together with the object of the group class as follows.
You may set the name to the level using the setTitle() technique of the stage class. The primaryStage is a level object that is passed to the start method of the scene class as a parameter.
Using the primaryStage object, set the title of the scene as sample application as follows.
You may add a Scene object to the stage the use of the method setScene() of the class named stage. upload the Scene object prepared inside the previous steps the usage of this method as follows.
Display the contents of the scene using the method named show() of the Stage class as follows.
Launch the JavaFX application through calling the static method launch()of the application class from the primary method as follows.
Following is a program which generates an arc. Save this code in a file with the name ArcExample.java.
Collect and execute the saved Java file from the command prompt using the following commands.
On executing, the above program generates a JavaFX window displaying an arc as shown in the following screenshot.
