Application of Java framework and C# framework in desktop application development

Java and C# frameworks provide a range of pre-built components and features for desktop application development, simplifying the development process. Major frameworks in Java include JavaFX, Swing, and Eclipse SWT, while major frameworks in C# include Windows Presentation Foundation (WPF), Windows Forms, and Universal Windows Platform (UWP). Practical examples showing how to use frameworks to create simple desktop applications in JavaFX and WPF.

Application of Java and C# frameworks in desktop application development

Java and C# frameworks are powerful tools for developing desktop applications tool. They provide a range of pre-built components and features that can greatly simplify the development process.

Java Framework

The main frameworks used for desktop application development in Java are:

• JavaFX: A comprehensive framework providing UI components and APIs for creating cross-platform applications.
• Swing: A lightweight framework optimized for the Java SE platform.
• Eclipse SWT: A fast and robust framework for building rich client applications.

C# Framework

The main frameworks used for desktop application development in C# are:

• Windows Presentation Foundation (WPF): A modern framework focused on creating beautiful and responsive user interfaces.
• Windows Forms: A proven framework for developing classic Windows desktop applications.
• Universal Windows Platform (UWP): A cross-platform framework that enables developers to create applications for Windows 10 devices including desktops, laptops, tablets, and phones.

Practical case

Java desktop application using JavaFX

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class JavaFXExample extends Application {

    @Override
    public void start(Stage stage) {
        Button button = new Button("Click Me!");
        StackPane root = new StackPane();
        root.getChildren().add(button);
        Scene scene = new Scene(root, 300, 250);
        stage.setScene(scene);
        stage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

C#Desktop application using WPF

using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;
using System.Windows.Media;

namespace WPFExample
{
    public partial class MainWindow : Window
    {
        private Button button;

        public MainWindow()
        {
            InitializeComponent();
            button = new Button();
            button.Content = "Click Me!";
            button.HorizontalAlignment = HorizontalAlignment.Center;
            button.VerticalAlignment = VerticalAlignment.Center;
            button.Width = 100;
            button.Height = 50;
            button.Click += Button_Click;
            this.Content = button;
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("Button clicked!");
        }
    }
}

These cases show how to use the framework to create simple desktop applications in Java and C#.
