Java Applet[編輯]

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[編輯]

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[編輯]

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

SPARQL[編輯]

SELECT ?h WHERE { 
  VALUES ?h { "Hello World" } 
}

[2]

XAML[編輯]

 <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>

接着使用 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!");
    }
  }
 }

易語言[編輯]

伺服器端[編輯]

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地址來檢視結果。

ASP[編輯]

<% Response.Write("Hello, world!") %>

[1]

或者簡單地寫成:
<%= "Hello, world!" %>

HTML[編輯]

<!-- 直接輸出... -->
Hello World
<!-- 或者 -->
<html>
<head>
    <title> Hello World </title>
</head>
<body>
Hello World
</body>
</html>

[1]

Go[編輯]

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[編輯]

<%
    out.print("Hello, world!");
%>

[1]

或者簡單地寫成:

<%="Hello, world!"%>

JavaScript[編輯]

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/');

PHP[編輯]

以下代碼既可以作為伺服器端執行,顯示在用戶瀏覽器上,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!"?>
