Explanation of Solution

Program:

//import the required headers

import javafx.application.Application;

import javafx.geometry.Pos;

import javafx.scene.Scene;

import javafx.scene.control.Button;

import javafx.scene.image.ImageView;

import javafx.scene.layout.BorderPane;

import javafx.scene.layout.HBox;

import javafx.stage.Stage;

import java.util.ArrayList;

//define the class Myclass

public class Myclass extends Application

{

@Override

//start method gets overidden in the application class

public void start(Stage primeview) {

// create a new list

ArrayList<Integer> mylist = new ArrayList<>();

// iterate for all cards

for (int iter = 1; iter <= 52; iter++)

{

// add the values to the list

mylist.add(iter);

}

// shuffle method call

java.util.Collections.shuffle(mylist);

// new Hbox declaration

HBox my_hBox = new HBox(5);

// set the alignment to be center

my_hBox.setAlignment(Pos.CENTER);

// add card 1 to the hbox

my_hBox.getChildren().add(new ImageView("exer1/image/card/" + mylist.get(0) + ".png"));

// add card 2 to the hbox

my_hBox.getChildren().add(new ImageView("exer1/image/card/" + mylist.get(1) + ".png"));

// add card 3 to the hbox

my_hBox.getChildren().add(new ImageView("exer1/image/card/" + mylist.get(2) + ".png"));

// add card 4 to the hbox

my_hBox.getChildren().add(new ImageView("exer1/image/card/" + mylist.get(3) + ".png"));

// new button gets created

Button btRefresh = new Button("Refresh");

// action event for the button gets created

btRefresh.setOnAction(e -> {

// shuffling the card

java.util.Collections.shuffle(mylist);

// clear the contents of the hbox

my_hBox.getChildren().clear();

// add card 1 to the hbox

my_hBox.getChildren().add(new ImageView("exer1/image/card/" + mylist.get(0) + ".png"));

// add card 2 to the hbox

my_hBox.getChildren().add(new ImageView("exer1/image/card/" + mylist.get(1) + ".png"));

// add card 3 to the hbox

my_hBox.getChildren().add(new ImageView("exer1/image/card/" + mylist.get(2) + ".png"));

// add card 4 to the hbox

my_hBox.getChildren().add(new ImageView("exer1/image/card/" + mylist.get(3) + ".png"));

});

// new border pane is created

BorderPane new_pane = new BorderPane();

// align the position

new_pane.setCenter(my_hBox);

// align the button position

new_pane.setBottom(btRefresh);

// add the contents to the pane

BorderPane.setAlignment(btRefresh, Pos.TOP_CENTER);

// new scene gets created

Scene n_scene = new Scene(new_pane, 250, 150);

// title of the stage is set

primeview.setTitle("Pick four cards");

// the stage gets placed in the scene

primeview.setScene(n_scene);

// stage gets displayed

primeview.show();

}

// main method

public static void main(String[] args)

{

// initilaize calls

launch(args);

}
