Empty program

Empty program
You are encouraged to solve this task according to the task description, using any language you may know.

In this task, the goal is to create the simplest possible program that is still considered "correct."

Ada

Compiler: GCC 4.1.2

  procedure Empty is begin null; end;

BASIC

Compiler: QBASIC

  END

C

Compiler: GCC 4.0.3

int main (int argc, char *argv[])
{
  return 0;
}

C++

Compiler: GCC 4.0.3

int main (int argc, char *argv[]) 
{
   return 0;
}

C#

Compiler: Microsoft (R) Visual C# 2005 Compiler version 8.00

static class Program
{
    static void Main(string[] args)
    {
    }
}

Haskell

Compiler: any Haskell98 compiler

module Main where

main :: IO ()
main = return ()

Java

Compiler: Sun javac, JDK 1.5.0 and up

public class EmptyMainClass {
    public static void main(String[] args) {
    }
}

public class EmptyApplet extends java.applet.Applet {
    @Override public void init() {
    }
}

Compiler: Sun javac, JDK 1.0 and Up

public class EmptyMainClass {
    public static void main(String[] args) {
    }
}

public class EmptyApplet extends java.applet.Applet {
    public void init() {
    }
}

@Override will be telling the compiler need to override this function. It's presents from JDK 5.0 (1.5.0) and up

Actually this is not strictly correct. The smallest possible correct program in Java is an empty source file.
