I have an issue when I tried to create multiple buttons with the same value of "x". How can I fix this issue or perhaps get the value of the buttons and then delete the specific element in an array with the same index as my button without deleting other elements as it loops through the for loop?

Button delButton = new Button[sizeOfIt]; //sizeOfIt is the size of array



for (int m=0; m <sizeOfIt; m++) {

    delButton[m]  = new Button("x");

}





for(int x = 0; x < delButton.length; x++) {                          

    delButton[x].setOnAction(new EventHandler<ActionEvent>() {     



        public void handle(ActionEvent event) {

        //  delete the element in the array with the same index as my button i clicked

        }

    });

}

You could handle this using the position of the button, it'll leave an empty box where the button was :

for(int x = 0; x < delButton.length; x++) {     

    final index = x;                     

    delButton[x].setOnAction(new EventHandler<ActionEvent>() {     

        public void handle(ActionEvent event) {

            delButton[index] = null;

        }

    });

}

@azro example keeps up with the index to get a reference to the Buttons. This example uses actionEvent.getSource() to get a reference to the Buttons.

import java.util.Arrays;

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.control.Button;

import javafx.scene.control.Control;

import javafx.scene.layout.StackPane;

import javafx.scene.layout.VBox;

import javafx.stage.Stage;



public class Main extends Application

{

    int sizeOfIt = 10;



    @Override

    public void start(Stage primaryStage)

    {

        Button delButton = new Button[sizeOfIt]; //sizeOfIt is the size of array

        VBox vBox = new VBox();



        for (int m = 0; m < sizeOfIt; m++) {

            delButton[m] = new Button(m + "x");

            delButton[m].setOnAction(actionEvent -> {

                for (int i = 0; i < delButton.length; i++) {

                    if (delButton[i] != null && delButton[i].equals((Button) actionEvent.getSource())) {

                        vBox.getChildren().remove(delButton[i]);

                        delButton[i] = null;

                        System.out.println(Arrays.toString(delButton));

                    }

                }

            });

        }



        vBox.getChildren().addAll(delButton);

        vBox.setMaxSize(Control.USE_PREF_SIZE, Control.USE_PREF_SIZE);



        StackPane root = new StackPane(vBox);

        Scene scene = new Scene(root);

        primaryStage.setScene(scene);

        primaryStage.show();



    }



    public static void main(String args)

    {

        launch(args);

    }
