title: Graphics2D in Java
body: <p>Firstly, sorry for this type of question.
  I´m learning <code>Java</code> programming, I have quite a lot skills in this language, but until now I haven´t used graphics2D. I want to learn how to create graphics, but I haven´t found any helpful tutorial. Please, do you know some good tutorial about learning how to create graphics? Thanks in advance.</p>
