以下是Hello, world!程序的列表。
Hello, world!程序使“Hello, world!”文本显示在计算机屏幕上。这通常是学习编程语言时遇到的第一个程序。或者，它是对新编程语言安装的基本健全性检查。如果“Hello World”无法运行，则在解决安装问题之前，不要尝试开发复杂的程序。
要查看更多语言，请查看Hello World 集合。
需要注意的是，4DOS/4NT 批处理语言是 MS-DOS 批处理语言的超集。
@echo Hello, world!
message "Hello, world!" with style = popup;
REPORT ZHELLO.
START-OF-SELECTION.
WRITE "Hello, world!".
以下示例使用了单例模式，并在消息框中输出文本，而不是传统的列表输出。
REPORT ZHELLO.
CLASS lcl_hello DEFINITION CREATE PRIVATE FINAL.
PUBLIC SECTION.
CLASS-DATA self TYPE REF TO lcl_hello READ-ONLY.
CLASS-METHODS class_constructor.
METHODS say_hello.
PRIVATE SECTION.
CONSTANTS con_hello_world TYPE c LENGTH 13 VALUE 'Hello, World!'.
ENDCLASS.
CLASS lcl_hello IMPLEMENTATION.

ENDMETHOD.
METHOD say_hello.
MESSAGE con_hello_world TYPE 'I'.
ENDMETHOD.
ENDCLASS.
START-OF-SELECTION.
lcl_hello=>self->say_hello( ).
WRITE "Hello, world!"
这将只输出到输出窗口，最终用户不会看到。
trace("Hello, world!");
此版本将对最终用户可见。
var helloWorld:TextField = this.createTextField( "helloWorld", this.getNextHighestDepth(), 1, 1, 100, 20 );
helloWorld.text = "Hello, world!";
package
{
public class HelloWorld
{
public function HelloWorld()
{
trace("Hello, world!");
}
}
}
with Ada.Text_IO;
procedure Hello is
begin
Ada.Text_IO.Put_Line ("Hello, world!");
end Hello;
ALGOL 68 标准要求保留字、类型和运算符使用不同的字体。因此，程序通常以粗体或下划线字体发布，例如
begin
printf($"Hello, world!"l$)
end
在流行的大写粗体词约定中
BEGIN
printf($"Hello, world!"l$)
END
或使用类似维基文本的引号标记，这在只有 6 位字符的计算机上特别适用（因此只有大写）
'BEGIN'
PRINTF($"HELLO, WORLD!"L$)
'END'
或者至少使用begin和end的“简短符号”形式。
( printf($"Hello, world!"l$) )
PROC main()
WriteF('Hello, world!');
ENDPROC
此程序在启动后通过诊断接口发送消息。

∇R←HWΔPGM
[1] R←'HELLO WORLD!'
∇
- 第一行上的 Del 开始为名为 HWΔPGM 的程序定义函数。它是一个无元函数（没有参数，与一元或二元函数相反），它将返回一个显式结果，允许其他函数或 APL 原语使用返回的值作为输入。
- 标号为 1 的行将文本向量 'Hello, world!!' 赋值给变量 R
- 最后一行是另一个 Del，它结束函数定义。
当函数通过输入其名称来执行时，APL 解释器将文本向量赋值给变量 R，但是由于我们在另一个函数、原语或赋值语句中没有使用此值，解释器会将其返回到终端，从而在函数调用下方显示下一行上的文字。
会话将如下所示
HWΔPGM Hello, world!!
虽然不是一个程序，但是如果你只是向解释器提供文本向量而不将其分配给变量，它会将其返回到终端作为输出。请注意，用户输入会自动由解释器缩进 6 个空格，而结果则显示在新行开头。
'Hello, world!' Hello, world!!
return "Hello, world!"
或
display dialog "Hello, world!"
<% Response.Write("Hello, world!") %>

以下示例适用于任何符合 ANSI/ISO 标准的 BASIC 实现，以及大多数内置于或分发于 1970 年代和 1980 年代微型计算机中的实现（通常是 Microsoft BASIC 的某种变体）。
10 PRINT "Hello, world!"
20 END
请注意，“END”语句在许多 BASIC 实现中是可选的。
一些实现也可以在省略行号时以立即模式执行指令。以下示例无需 RUN 指令即可执行。
PRINT "Hello, world!"
? "Hello, world!"
BASIC 的后期实现允许对结构化编程提供更大的支持，并且不需要源代码的行号。以下示例在大多数现代 BASIC 中运行时有效。
PRINT "Hello, world!"
END
同样，“END”语句在许多 BASIC 中是可选的。

PICK/BASIC、DATA/BASIC、MV/BASIC
[edit | edit source]除了本文开头提到的 ANSI 语法之外，大多数 Pick 操作系统版本的 Dartmouth BASIC 支持扩展语法，允许对 VDT 使用光标放置和其他 terminfo 类型功能
X、Y 定位（冒号“:”是连接指令）
PRINT @(34,12) : "Hello, world!"
将在 80X24 CRT 中大致居中显示字符串“Hello, world！”。
其他功能
PRINT @(-1) : @(34,12) : "Hello, world!"
将在 80X24 CRT 中大致居中显示字符串“Hello, world！”之前清除屏幕。
语法变体
CRT "Hello, world!"
支持上面的“@”函数，CRT 语句会忽略之前的 PRINTER 语句，始终将输出发送到屏幕。
某些 Pick 操作系统环境（如 OpenQM）支持 PRINT 的 DISPLAY 变体。除了“@”函数之外，此变体还会根据 TERM 变量的设置维护分页
DISPLAY "Hello, world!"

JavaFX 脚本是以前称为 F3（形式遵循功能）的脚本语言。它于 2010 年被 Oracle 停止使用。
Frame {
title: "Hello World JavaFX"
width: 200
content: Label {
text: "Hello World"
}
visible: true
}
这个程序也可以这样写
var win = new Frame();
win.title = "Hello World JavaFX";
win.width = 200;
var label = new Label();
label.text = "Hello World";
win.content = label;
win.visible = true;
一个简单的控制台输出版本将是
import java.lang.System;
System.out.println("Hello World");
甚至更简单（使用内置函数）
println("Hello World");
JavaScript 没有本地（内置）输入或输出例程。相反，它依赖于其宿主环境提供的功能。
使用标准 Web 浏览器的文档对象
document.write('Hello, World!');
或使用警报，使用标准 Web 浏览器的窗口对象 (window.alert)
alert('Hello, world!');
或者，从 Mozilla 命令行实现
print('Hello, world!');
或者，从 Windows 脚本宿主
WScript.Echo('Hello, world!');
或者，从 Firebug、Apple Safari 或 Google Chrome 调试控制台

Oberon 既是编程语言的名称，也是操作系统的名称。
为 Oberon 操作系统编写的程序

Texts.WriteLn(W);
Texts.Append(Oberon.Log, W.buf)

PHP 是一种模板语言，会直接回显不在 PHP 标签中的任何文本，因此最简单的形式是
Hello, world!
使用实际的 PHP 语句，它可以写成
<?php
echo 'Hello, world!';
?>
或者使用简短的回显，语法如下
<? echo "Hello, world!"?>
这也将有效
<?= "Hello, world!" ?>
int main() {
write("Hello, world!\n");
return 0;
}
T:Hello, world!
set serveroutput on size 1000000; -- this is a SQL*Plus command to enable the output buffer
begin
dbms_output.put_line('Hello, world!');

这在 Python 2.4 或更高版本上也能工作，但以一种不直观的方式。在 Python 3 中，它调用带有字符串 "Hello, world!" 的 print 函数。在 Python 2 中，它使用表达式 ("Hello, world!") 执行 print 语句，该表达式计算为字符串 "Hello, world!"。
import sys
sys.stdout.write("Hello, world!\n")
在 Python 2.6 或更高版本中
from __future__ import print_function
print("Hello, world!")
import __hello__
import __phello__
from math import cos, sin
def f(x):
return int(round(96.75 + -21.98*cos(x*1.118) + 13.29*sin(x*1.118) + -8.387*cos(2*x*1.118)\

print("".join([chr(f(x)) for x in range(12)]))
可以通过以下方法实现“Hello, world!”（带引号）
'Hello, world!'
#!/usr/local/bin/python
print("Content-type: text/html\n\n")
print("Hello World!")

d TestMessage c Const( 'Hello, world!' )
c TestMessage DSPLY
c EVAL *InLR = *On
使用内部消息窗口，一个简单的 Hello, world! 程序可以这样呈现
mwin("Hello, world!")
wait()
另一种渲染文字的方法是使用内置的 text() 函数。
text(1,1,"Hello, world!") wait()

下面 C# 程序的功能等效项。
简单来说，使用消息框
public class HelloWorld
{
static void Main()
{
System.Windows.Forms.MessageBox.Show("Hello, world!");
}
}
或者
using System;
using System.Drawing;
using System.Windows.Forms;

public static void Main()
{
Application.Run(new HelloWorldForm());
}
public HelloWorldForm()
{
Label label = new Label();
label.Text = "Hello, world!";
label.Location = new Point(40,30);
this.Controls.Add(label);
Button button = new Button();
button.Text = "OK";
button.Location = new Point(50,55);
this.Controls.Add(button);
button.Click += new EventHandler(button_Click);
}
private void button_Click(Object sender, EventArgs e)

实现此目的的最简单方法是使用内置的消息函数，该函数类似于 windows messageBox()。
PROGRAM

调用此方法的一种方式是在 Erlang shell 中输入hello_world:hello()。另一种方法是从命令行运行
erl -noshell -run hello_world hello -run init stop
仅限 MS-Windows - 基本。
include msgbox.e
if message_box("Hello, world!", "Hello", 0) then end if
仅限 MS-Windows - 使用 Win32Lib 库
include win32lib.ew
createForm({
";Window; Hello",
";Label; Hello, world!"
})
include w32start.ew

let _ = System.Windows.Forms.MessageBox.Show("Hello, world!");;

Hello World Cake with Chocolate sauce. This prints hello world, while being tastier than Hello World Souffle. The main chef makes a " world!" cake, which he puts in the baking dish. When he gets the sous chef to make the "Hello" chocolate sauce, it gets put into the baking dish and then the whole thing is printed when he refrigerates the sauce. When actually cooking, I'm interpreting the chocolate sauce baking dish to be separate from the cake one and Liquify to mean either melt or blend depending on context. Ingredients. 33 g chocolate chips 100 g butter 54 ml double cream 2 pinches baking powder 114 g sugar 111 ml beaten eggs 119 g flour 32 g cocoa powder 0 g cake mixture Cooking time: 25 minutes.

Act I: Hamlet's insults and flattery.
Scene I: The insulting of Romeo.
[Enter Hamlet and Romeo]
Hamlet:
You lying stupid fatherless big smelly half-witted coward!
You are as stupid as the difference between a handsome rich brave
hero and thyself! Speak your mind!
You are as brave as the sum of your fat little stuffed misused dusty
old rotten codpiece and a beautiful fair warm peaceful sunny summer's
day. You are as healthy as the difference between the sum of the
sweetest reddest rose and my father and yourself! Speak your mind!
You are as cowardly as the sum of yourself and the difference
between a big mighty proud kingdom and a horse. Speak your mind.
Speak your mind!
[Exit Romeo]
Scene II: The praising of Juliet.
[Enter Juliet]
Hamlet:
Thou art as sweet as the sum of the sum of Romeo and his horse and his
black cat! Speak thy mind!
[Exit Juliet]
Scene III: The praising of Ophelia.
[Enter Ophelia]
Hamlet:
Thou art as lovely as the product of a large rural town and my amazing
bottomless embroidered purse. Speak thy mind!
Thou art as loving as the product of the bluest clearest sweetest sky
and the sum of a squirrel and a white horse. Thou art as beautiful as
the difference between Juliet and thyself. Speak thy mind!
[Exeunt Ophelia and Hamlet]
Act II: Behind Hamlet's back.
Scene I: Romeo and Juliet's conversation.
[Enter Romeo and Juliet]
Romeo:
Speak your mind. You are as worried as the sum of yourself and the
difference between my small smooth hamster and my nose. Speak your
mind!
Juliet:
Speak YOUR mind! You are as bad as Hamlet! You are as small as the
difference between the square of the difference between my little pony
and your big hairy hound and the cube of your sorry little
codpiece. Speak your mind!
[Exit Romeo]
Scene II: Juliet and Ophelia's conversation.
[Enter Ophelia]
Juliet:
Thou art as good as the quotient between Romeo and the sum of a small
furry animal and a leech. Speak your mind!
Ophelia:
Thou art as disgusting as the quotient between Romeo and twice the
difference between a mistletoe and an oozing infected blister! Speak
your mind!
