**Java**
import java.awt.*;
import java.awt.event.*;
public class HelloFrame extends Frame

{
super.paint(g);
java.awt.Insets ins = this.getInsets();
g.drawString("Hello, World!", ins.left + 25, ins.top + 25);

Hello World
HelloWorld Program says:
Java代碼：

{
g.drawString("Hello, world!", 100, 50);
}
}

**JavaScript**
JavaScript是一種腳本語言。最廣泛用於HTML文件中，也可以用在其它宿主環境下，比如Microsoft® Windows® 腳本宿主（WSH）和一些web服務環境。
用於HTML中： 
// 彈出對話框
alert("Hello, World!");
// 在頁面上顯示
document.write("Hello, World!");
用於WSH中：
WScript.Echo("Hello, World!");
作為服務器端（Node.js）：啟動後，需要在瀏覽器中訪問“ 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**
PostScript是一種專門用來創建圖像的語言，常用於打印機。 
/font /Courier findfont 24 scalefont
font setfont
100 100 moveto
(Hello World!) show
showpage

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

以下為Web服務端示例程序，程序啟動後，需要用瀏覽器訪問特定地址來查看結果。

**ASP**
或者簡單地寫成：

**HTML**
Hello World
Hello World 
Hello World

**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**
或者簡單地寫成：

**JavaScript**
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**
以下代碼既可以作為服務器端運行，顯示在用戶瀏覽器上，也可以在終端中直接運行，輸出到終端中：
