Question

Using JAVA FX how would I combine the two programs below into one interface that allows the user to pick which specific program they would like to play. They should be able to choose which one they want to play and then switch between them if necesary. All of this must be done in JAVA FX code

Answer 1

Hi Sir, I am suggesting you an easy way to launch either of the two JavaFX Game Application based on user Input. Create a Java Class "LaunchJavaFXGame.java", and copy the copy below:-

1. LaunchJavaFXGame.java

import javafx.application.Application;

import javafx.event.ActionEvent;

import javafx.event.EventHandler;

import javafx.scene.Scene;

import javafx.scene.control.Button;

import javafx.scene.layout.GridPane;

import javafx.stage.Stage;

public class LaunchJavaFXGame extends Application {

public Button b0, b1;

@Override

public void start(Stage primaryStage) {

GridPane grid = new GridPane();

b0 = new Button("Launch MyCalendar Application");

b0.setId("0");

b0.setMaxSize(Double.MAX_VALUE, Double.MAX_VALUE);

grid.add(b0, 0, 1);

b1 = new Button("Launch BlackJack Application");

b1.setId("1");

b1.setMaxSize(Double.MAX_VALUE, Double.MAX_VALUE);

grid.add(b1, 1,1);

Scene scene = new Scene(grid, 400, 100);

primaryStage.setScene(scene);

primaryStage.setResizable(false);

primaryStage.setTitle("JavFX Game Launcher");

primaryStage.show();

b0.setOnAction(new EventHandler<ActionEvent>() {

@Override

public void handle(ActionEvent event) {

//create an object of the class you wish to invoke its start() method:

MyCalendar myCalendarObj = new MyCalendar();

// Then call its start() method in the following way:

myCalendarObj.start(primaryStage);

}// End handle(ActionEvent event)

});// End anonymous class

b1.setOnAction(new EventHandler<ActionEvent>() {

@Override

public void handle(ActionEvent event) {

//create an object of the class you wish to invoke its start() method:

Main mainObj = new Main();

// Then call its start() method in the following way:

mainObj.start(primaryStage);

}// End handle(ActionEvent event)

});// End anonymous class

}

public static void main(String[] args) {

launch(args);

}

}

The output is attached below:-

On clicking any game that you want to launch from this Game Chooser JavaFX, the corresponding application will open:-

Please let me know in case of any clarifications required. Thanks!
