"Hello, world!" 用一个程序 xmessage 'Hello, world!' 使用Qt #include <QApplication> #include <QLabel> int main(int argc, char *argv[]) { QApplication app(argc, argv); QLabel label("Hello, world!"); label.show(); return app.exec(); } C 和 GTK+ #include <gtk/gtk.h> int main(int argc, char * args[]) { GtkWidget * win, * label; gtk_init(& argc, & args); label = gtk_label_new("Hello, world!"); win = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_container_add(GTK_CONTAINER(win), label); gtk_widget_show_all(); gtk_main(); return 0; } 用C++和gtkmm 2 #include <iostream> #include <gtkmm/main.h> #include <gtkmm/button.h> #include <gtkmm/window.h> using namespace std; class HelloWorld : public Gtk::Window { public: HelloWorld(); virtual ~HelloWorld(); protected: Gtk::Button m_button; virtual void on_button_clicked(); }; HelloWorld::HelloWorld() : m_button("Hello, world!") { set_border_width(10); m_button.signal_clicked().connect(SigC::slot(*this, &HelloWorld::on_button_clicked)); add(m_button); m_button.show(); } HelloWorld::~HelloWorld() {} void HelloWorld::on_button_clicked() { cout << "Hello, world!" << endl; } int main（int argc, char *argv[]） { Gtk::Main kit(argc, argv); HelloWorld helloworld; Gtk::Main::run(helloworld); } import java.awt.*; import java.awt.event.*; public class HelloFrame extends Frame { HelloFrame(String title) { super(title); } public void paint(Graphics g) { super.paint(g); java.awt.Insets ins = this.getInsets(); g.drawString("Hello, World!", ins.left + 25, ins.top + 25); } public static void main(String args []) { HelloFrame fr = new HelloFrame("Hello"); fr.addWindowListener( new WindowAdapter() { public void windowClosing(WindowEvent e) { System.exit( 0 ); } } ); fr.setResizable(true); fr.setSize(500, 100); fr.setVisible(true); } } Java Applet用于HTML文件。 HTML代码： <html> <head> <title>Hello World</title> </head> <body> HelloWorld Program says: <applet code="HelloWorld.class" width="600" height="100"> </applet> </body> </html> Java代码： import java.applet.*; import java.awt.*; public class HelloWorld extends Applet { public void paint(Graphics g) { g.drawString("Hello, world!", 100, 50); } } JavaScript是一种脚本语言。最广泛用于HTML文件中，也可以用在其它宿主环境下，比如Microsoft® Windows® 脚本宿主（WSH）和一些web服务环境。 用于HTML中： // 弹出对话框 alert("Hello, World!"); // 在页面上显示 document.write("Hello, World!"); 用于WSH中： WScript.Echo("Hello, World!"); 作为服务器端（Node.js）：启动后，需要在浏览器中访问“http://127.0.0.1:8000/”查看。 const http = require('http'); http.createServer((request, response) => { response.writeHead(200, { 'Content-Type': 'text/plain' }); response.end('Hello World!'); }).listen(8000); console.log('Server running at http://127.0.0.1:8000/'); PostScript是一种专门用来创建图像的语言，常用于打印机。 /font /Courier findfont 24 scalefont font setfont 100 100 moveto (Hello World!) show showpage SELECT ?h WHERE { VALUES ?h { "Hello World" } } <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="XAMLSample.Page1" > <Button Click="HelloWorld" Name="Button1">Click Here</Button> </Page> 接著使用 C# 建置 using System; using System.Windows; using System.Windows.Controls; namespace XAMLSample { public partial class Page1 : Page { void HelloWorld(object sender, RoutedEventArgs e) { MessageBox.Show("Hello, world!"); } } } .版本 2 .程序集 窗口程序集1 .子程序 __启动窗口_创建完毕 信息框 (“Hello, World!”, 0, ) 以下为Web服务端示例程序，程序启动后，需要用浏览器访问特定地址来查看结果。 <% Response.Write("Hello, world!") %> 或者簡單地寫成： <%= "Hello, world!" %> <!-- 直接輸出... --> Hello World <!-- 或者 --> <html> <head> <title> Hello World </title> </head> <body> Hello World </body> </html> package main import ( "fmt" "net/http" ) func helloHandler(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "hello world") } func main() { http.HandleFunc("/", helloHandler) http.ListenAndServe("0.0.0.0:8000", nil) } <% out.print("Hello, world!"); %> 或者简单地写成： <%="Hello, world!"%> 以下为Node.js环境： const http = require('http'); http.createServer((request, response) => { response.writeHead(200, { 'Content-Type': 'text/plain' }); response.end('Hello World!'); }).listen(8000); console.log('Server running at http://127.0.0.1:8000/'); 以下代码既可以作为服务器端运行，显示在用户浏览器上，也可以在终端中直接运行，输出到终端中： <?php echo 'Hello, world!'; // 或者 print 'Hello, world!'; ?> 或者 <?= "Hello World!"?> Hello World The Hello World Collection （页面存档备份，存于互联网档案馆） helloworldcollection.de [2014-12-12] leachim6/hello-world/ （页面存档备份，存于互联网档案馆） GitHub [2021-06-20] GitHub上的Hello World程序样例集 （页面存档备份，存于互联网档案馆）
