Mnd is learning Java!

Yeah, I know. I got "afk" for three days but I'm back, I'll post that three codes that I got to post, sorry, blame my god-dammed exams.
Now I'm trying to learn Java for Android development so, when I do my first program, I'll upload a .zip with the entire project, I use Eclipse IDE.
I've done a "Hello, World" Android app (it's so easy, just do a new project and Eclipse creates a project with "Hello, world!" code by default) but there's too, TOO MUCH to learn.
So stay tuned!

Hello, world!

A simple showing message program used to teach programming languages, this will be the first program you learn.

#include <stdio.h>

main()
{
      printf("Hello, world!");
      getchar();
}
