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:

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用於HTML檔案。
HTML代碼：
<html>
<head>
<title>Hello World</title>
</head>
<body>
HelloWorld Program says:
<applet code="HelloWorld.class" width="600" height="100">
</applet>
</body>
</html>
Java代碼：
import java.applet.*;
import java.awt.*;
public class HelloWorld extends Applet
{
public void paint(Graphics g)
{
g.drawString("Hello, world!", 100, 50);
}
}
JavaScript是一種手稿語言。最廣泛用於HTML檔案中，也可以用在其它宿主環境下，比如Microsoft® Windows® 指令碼宿主（WSH）和一些web服務環境。
用於HTML中：
// 弹出对话框
alert("Hello, World!");
// 在页面上显示
document.write("Hello, World!");
用於WSH中：
WScript.Echo("Hello, World!");
作為伺服器端（Node.js）：啟動後，需要在瀏覽器中訪問「http://127.0.0.1:8000/」檢視。
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是一種專門用來建立圖像的語言，常用於印表機。
/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, )
以下為Web伺服器端範例程式，程式啟動後，需要用瀏覽器訪問特定位址來檢視結果。
<% Response.Write("Hello, world!") %>
<%= "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!");
%>
或者簡單地寫成：
<%="Hello, world!"%>
以下為Node.js環境：
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/');
以下代碼既可以作為伺服器端執行，顯示在使用者瀏覽器上，也可以在終端中直接執行，輸出到終端中：
<?php
echo 'Hello, world!';
// 或者
print 'Hello, world!';
?>
或者
<?= "Hello World!"?>
