D vs Java

D programs are bigger than C and Java, but smaller than C++ ?
Here are some old Hello test results I had: (on Mac OS X 10.3)

31b     hello.sh (script)
Hello, World!
         0.01 real         0.00 user         0.00 sys

  12K    hello_c (executable)
Hello, World!
         0.03 real         0.00 user         0.00 sys

368K    hello_cpp (including libstdc++)
Hello, World!
         0.09 real         0.00 user         0.02 sys

104K    hello_d (including Phobos)
Hello, World!
         0.04 real         0.01 user         0.01 sys

637b    hello.jar (archive)
Hello, World!
         0.66 real         0.38 user         0.19 sys

Results for C, C++, D, Java 1.4 and Bourne Shell respectively...
If the Java runtime comes with the system, Java's really small !
(then again, it's also the far slowest to start up and execute
which makes it less suitable for small programs like this one)


BTW:
Having a programming language that needs separate compilation
as a first language is pretty mean I think. But that's just me.
(better to go with a scripting language, such as Ruby or Python ?
and it avoids having to unlearn things picked up from Pascal...)

But I learned Pascal in school, and Ada in university. Hated both. :)
I think you need to learn at least three languages. Preferrably more.

PS.

#!/bin/sh
echo "Hello, World!"

-----------------------------------------
#include <stdio.h>

int main(int argc, char *argv[])
{
     puts("Hello, World!");
     return 0;
}

-----------------------------------------
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
     cout << "Hello, World!" << endl;
     return 0;
}

-----------------------------------------
import std.stdio;

void main()
{
     writeln("Hello, World!");
}

-----------------------------------------
public class hello
{
   public static void main(String[] args)
   {
     System.out.println("Hello, World!");
   }
}
