Or to have the OS synthesize it and literally speak out the words "hello world!" (with no comma, as that would cause the synthesizer to pause)

say "Hello world!"

Java applet

Java applets work in conjunction with HTML files.
<HTML><HEAD><TITLE>Hello World</TITLE></HEAD><BODY>HelloWorld Program says:<APPLET CODE="HelloWorld.class" WIDTH=600 HEIGHT=100></APPLET>

import import public class HelloWorld extends Applet {  public void paint (Graphics g) {    g.drawString ("Hello, world!", 100, 50) ;  }}

JavaScript and JScript

JavaScript (an implementation of ECMAScript) is a client-side scripting language used in HTML files. The following code can be placed in any HTML file: { alert ("Hello, world!") ; } //--></script> <a href="#" onclick="helloWorld () ; return false;">Hello World Example</a>An easier method uses JavaScript implicitly, directly calling the reserved alert function. Cut and paste the following line inside the <body> .... </body> HTML tags.
<a href="#" onclick="alert ('Hello, world!') ; return false;">Hello World Example</a>
An even easier method involves using popular browsers' support for the virtual 'javascript' protocol to execute JavaScript code. Enter the following as an Internet address (usually by pasting into the address box) :
javascript:alert ('Hello, world!') ;

ไฟล์:Js-hello world.png

There are many other ways:
javascript:document.write ('Hello, world!\n') ;

Windows API (in C)

This uses the Windows API to create a full window containing the text. Another example below uses the built-in MessageBox function instead.

#include <windows.h>LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM) ;char szClassName[] = "MainWnd";int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine,                   int nCmdShow){  HWND hwnd;  MSG msg;  WNDCLASSEX wincl;  wincl.cbSize = sizeof (WNDCLASSEX) ;  wincl.cbClsExtra = 0;  wincl.cbWndExtra = 0;  wincl.style = 0;  wincl.hInstance = hInstance;  wincl.lpszClassName = szClassName;  wincl.lpszMenuName = NULL; //No menu  wincl.lpfnWndProc = WindowProcedure;  wincl.hbrBackground = (HBRUSH) (COLOR_WINDOW + 1) ; //Color of the window  wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION) ; //EXE icon  wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION) ; //Small program icon  wincl.hCursor = LoadCursor (NULL, IDC_ARROW) ; //Cursor  if (!RegisterClassEx (&wincl))        return 0;  hwnd = CreateWindowEx (0, //No extended window styles        szClassName, //Class name        "", //Window caption        WS_OVERLAPPEDWINDOW & ~WS_MAXIMIZEBOX,        CW_USEDEFAULT, CW_USEDEFAULT, //Let Windows decide the left and top                                      //positions of the window        120, 50, //Width and height of the window,        NULL, NULL, hInstance, NULL) ;  //Make the window visible on the screen  ShowWindow (hwnd, nCmdShow) ;  //Run the message loop  while (GetMessage (&msg, NULL, 0, 0) >0)  {        TranslateMessage (&msg) ;        DispatchMessage (&msg) ;  }  return msg.wParam;}LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message,                                 WPARAM wParam, LPARAM lParam){  PAINTSTRUCT ps;  HDC hdc;  switch (message)  {  case WM_PAINT:        hdc = BeginPaint (hwnd, &ps) ;        TextOut (hdc, 15, 3, "Hello, world!", 13) ;        EndPaint (hwnd, &ps) ;        break;  case WM_DESTROY:        PostQuitMessage (0) ;        break;  default:        return DefWindowProc (hwnd, message, wParam, lParam) ;  }  return 0;}

Or, much more simply:

#include <windows.h>int WINAPI WinMain (HINSTANCE hInst, HINSTANCE hPrevInstance, LPSTR lpCmdLine,                   int nCmdShow){    MessageBox (NULL, "Hello, world!", "", MB_OK) ;    return 0;}

Windows Script Host with VBScript

<job id="HelloWorld">        <script language="VBScript">                WScript.Echo "Hello, world!"        </script></job>

Windows Script Host with JScript

<job id="HelloWorld">        <script language="JScript">                WScript.Echo ( "Hello, world!" ) ;        </script></job>

XSL (T)

There are many ways to do this in XSL, the simplest being:

<xsl:template match="/">  <xsl:text>Hello, world!</xsl:text></xsl:template>

If nested similar to the HTML version, it would be:

<xsl:template match="/">  <html>    <body>      <h1>Hello, world!</h1>    </body>  </html></xsl:template>

XUL

Type the following in a text file (e.g. hello.world.xul) and then open with Mozilla Firefox.

<window xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">  <box align="center" pack="center" flex="1">    <description>Hello, world</description>  </box></window>
