Block 1: Import Statements

import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.ObjectInputStream; import java.io.ObjectOutputStream; import javafx.application.Application; import javafx.geometry.Insets; import javafx.scene.Scene; import javafx.scene.control.Alert; import javafx.scene.control.Button;

• This block contains import statements for various Java and JavaFX classes used in the application.

Block 2: Class Declaration and Object Initialization

public class Main extends Application { private static ClubList clubList = new ClubList(); private static StadiumList stadiumList = new StadiumList(); private static PlayerList playerList = new PlayerList(); private static MatchList matchList = new MatchList(); // ... (main method and start method) }

• Here, the Main class extends Application and initializes static instances of ClubList, StadiumList, PlayerList, and MatchList.

Block 3: Main Method

public static void main(String[] args) { new Thread(() -> launch(args)).start(); }

• The main method launches the JavaFX application in a new thread.

Block 4: Start Method

@Override public void start(Stage primaryStage) { // ... (GUI setup, button creation, scene creation, etc.) loadData(); primaryStage.setOnCloseRequest(event -> { saveData(); }); }

• The start method sets up the graphical user interface, initializes data using loadData(), and handles the closing event by saving data using saveData().

Block 5: Button Action Methods

private void addClub() { // ... (method for adding a club) } private void addStadium() { // ... (method for adding a stadium) } // ... (similar methods for adding player, scheduling match, playing match, etc.)

• These methods handle the actions performed when various buttons (e.g., "Add Club," "Add Stadium") are clicked. They open new stages, take user input, and perform actions accordingly.

Block 6: Serialization Methods

private static void saveData() { // ... (method for saving data to a file using serialization) } private static void loadData() { // ... (method for loading data from a file using serialization) }

• These methods handle the serialization and deserialization of data to/from a file, allowing the application state to be saved and loaded.

Block 7: Exit Method

private static void exit() { saveData(); System.out.println("Exiting the program..."); System.exit(0); }

• This method is not directly used in the provided code, but it saves data and exits the program when called.

Block 8: Showing Details Methods

private void getTeamDetail() { // ... (method for getting and displaying details of a team) } // ... (similar methods for getting and displaying details of stadium, player, match, etc.)

• These methods handle actions related to displaying details of clubs, stadiums, players, and matches. They open new stages with input fields and display relevant information.

Block 9: Display Lists Methods

These methods open new stages with lists of players, stadiums, clubs, fixtures, results, etc., using JavaFX ListView.

Block 10: Removing Player Method

private void removePlayer() { // ... (method for removing a player) }

• This method opens a stage with an input field to enter the player ID for removal and displays information messages using JavaFX Alert.

Block 11: Serialization Methods Implementation

private static void saveData() { // ... (implementation for saving data using serialization) } private static void loadData() { // ... (implementation for loading data using serialization) }

• These methods contain the actual implementation of saving and loading data using Java serialization.

Block 12: JavaFX ListCell Customization

listView.setCellFactory(param -> new ListCell () { // ... (customization for displaying player details in a ListView) } );

• This code sets a custom ListCell for the JavaFX ListView to display player details in a formatted way.

Block 13: Main Method Call

new Thread(() -> launch(args)).start();

• This line starts the JavaFX application in a new thread.

Conclusion

In conclusion, the provided Java code represents a Football Management Application utilizing JavaFX for the user interface. The program employs various classes and methods to manage football clubs, stadiums, players, and matches. The graphical interface allows users to perform actions such as adding clubs, scheduling matches, and displaying detailed information about teams, players, and fixtures. Additionally, the application supports data persistence through serialization, enabling the saving and loading of the program's state. The modular design enhances code readability and maintainability. Overall, this Football Management App serves as a comprehensive tool for managing and exploring various aspects of football teams and matches.
