CheckBox(String str) Constructor is undefined - checkbox

Question

I am trying to make a CheckBox using javafx-8 but the constructor which intialises the label associated with it that is CheckBox(String str) is not defined similarly the setSelected method and setText methods are not defined in the library.
I have updated java to the latest version Java SE 8u131 but the problem is still there.
Here's the code
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;import javafx.stage.Stage;
public class CheckBox extends Application {
Stage window;
Scene scene;
Button button;
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception {
window = primaryStage;
window.setTitle("JavaFX");
//Checkboxes
CheckBox box1 = new CheckBox("apples");
CheckBox box2 = new CheckBox("Tuna");
box2.setSelected(true);
//Button
button = new Button("Order Now!");
button.setOnAction(e -> handleOptions(box1, box2));
//Layout
VBox layout = new VBox(10);
layout.setPadding(new Insets(20, 20, 20, 20));
layout.getChildren().addAll(box1, box2, button);
scene = new Scene(layout, 300, 250);
window.setScene(scene);
window.show();
}
//Handle checkbox options
private void handleOptions(CheckBox box1, CheckBox box2){
String message = "Users order:\n";
if(box1.isSelected())
message += "Bacon\n";
if(box2.isSelected())
message += "Tuna\n";
System.out.println(message);
}
}
Here's the Error log
CheckBox.java:24: error: constructor CheckBox in class CheckBox cannot be applied to given types;
CheckBox box1 = new CheckBox("apples");

reason: actual and formal argument lists differ in length

where E is a type-variable:

I am using eclipse ide but its not problem of that too because i have tried compiling it through ubuntu's shell.
How should i rectify this ?
Thanks in Advance!

Answer 1

CheckBox is your class name,so rename your class name and import javafx checkbox
import javafx.scene.control.CheckBox;
or use fully qualified name like that.
javafx.scene.control.CheckBox box1 = new javafx.scene.control.CheckBox("apples");
javafx.scene.control.CheckBox box2 = new javafx.scene.control.CheckBox("Tuna");
In handleOptions() method
private void handleOptions(javafx.scene.control.CheckBox box1, javafx.scene.control.CheckBox box2) {
