Java.
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");

&lt;head&gt;
&lt;title&gt;Hello World&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
HelloWorld Program says:
&lt;applet code="HelloWorld.class" width="600" height="100"&gt;
&lt;/applet&gt;
&lt;/body&gt;
&lt;/html&gt;
Java代码：
import java.applet.*;
import java.awt.*;
public class HelloWorld extends Applet

JavaScript.
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) =&gt; {
 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.
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
SPARQL.
SELECT ?h WHERE { 
 VALUES ?h { "Hello World" } 
XAML.
 &lt;Page
 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 x:Class="XAMLSample.Page1"
 &lt;Button Click="HelloWorld" Name="Button1"&gt;Click Here&lt;/Button&gt;
 &lt;/Page&gt;
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!");

服务器端.
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。
ASP.
&lt;% Response.Write("Hello, world!") %&gt;
&lt;%= "Hello, world!" %&gt;
HTML.
&lt;!-- 直接输出... --&gt;
Hello World
&lt;!-- 或者 --&gt;
&lt;html&gt;
&lt;head&gt;
 &lt;title&gt; Hello World &lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
Hello World
&lt;/body&gt;
&lt;/html&gt;
Go.
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)
JSP.
 out.print("Hello, world!");
或者简单地写成：
&lt;%="Hello, world!"%&gt;
JavaScript.
以下为Node.js环境：
const http = require('http');
http.createServer((request, response) =&gt; {
 response.writeHead(200, { 'Content-Type': 'text/plain' });
 response.end('Hello World!');
}).listen(8000);
console.log('Server running at http://127.0.0.1:8000/');
PHP.
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：
&lt;?php
 echo 'Hello, world!';
 // 或者
 print 'Hello, world!';
或者
&lt;?= "Hello World!"?&gt;
